Fractures & Trauma

The ankle joint is composed of three bones: the tibia, fibula, and talus which are articulated together. The ends of the fibula and tibia (lower leg bones) form the inner and outer malleolus, which are the bony protrusions of the ankle joint that you can feel and see on either side of the ankle. The joint is protected by a fibrous membrane called a joint capsule, and filled with synovial fluid to enable smooth movement.

Ankle injuries are very common in athletes and in people performing physical work, often resulting in severe pain and impaired mobility. Pain after ankle injuries can either be from a torn ligament and is called ankle sprain or from a broken bone which is called ankle fracture. Ankle fracture is a painful condition where there is a break in one or more bones forming the ankle joint. The ankle joint is stabilized by different ligaments and other soft tissues, which may also be injured during an ankle fracture.

Causes

Ankle fractures occur from excessive rolling and twisting of the ankle, usually occurring from an accident or activities such as jumping or falling causing sudden stress to the joint.

Symptoms

With an ankle fracture, there is immediate swelling and pain around the ankle as well as impaired mobility. In some cases, blood may accumulate around the joint, a condition called hemarthrosis. In cases of severe fracture, deformity around the ankle joint is clearly visible where bone may protrude through the skin.

Types of fractures

Ankle fractures are classified according to the location and type of ankle bone involved. The different types of ankle fractures are:

• Lateral Malleolus fracture in which the lateral malleolus, the outer part of the ankle is fractured.
• Medial Malleolus fracture in which the medial malleolus, the inner part of the ankle, is fractured.
• Posterior Malleolus fracture in which the posterior malleolus, the bony hump of the tibia, is fractured.
• Bimalleolar fractures in which both lateral and medial malleolus bones are fractured
• Trimalleolar fractures in which all three lateral, medial, and posterior bones are fractured.
• Syndesmotic injury, also called a high ankle sprain, is usually not a fracture, but can be treated as a fracture.

Diagnosis

The diagnosis of the ankle injury starts with a physical examination, followed by X-rays and CT scan of the injured area for a detailed view. Usually it is very difficult to differentiate a broken ankle from other conditions such as a sprain, dislocation, or tendon injury without having an X-ray of the injured ankle. In some cases, pressure is applied on the ankle and then special X-rays are taken. This procedure is called a stress test. This test is employed to check the stability of the fracture to decide if surgery is necessary or not. In complex cases, where detail evaluation of the ligaments is required an MRI scan is recommended.

Treatments

Immediately following an ankle injury and prior to seeing a doctor, you should apply ice packs and keep the foot elevated to minimize pain and swelling.

The treatment of ankle fracture depends upon the type and the stability of the fractured bone. Treatment starts with non-surgical methods, and in cases where the fracture is unstable and cannot be realigned, surgical methods are employed.

In non-surgical treatment, the ankle bone is realigned and special splints or a plaster cast is placed around the joint, for at least 2-3 weeks.

With surgical treatment, the fractured bone is accessed by making an incision over the ankle area and then specially designed plates are screwed onto the bone, to realign and stabilize the fractured parts. The incision is then sutured closed and the operated ankle is immobilized with a splint or cast.

Post-operative care

After ankle surgery, you will be instructed to avoid putting weight on the ankle by using crutches while walking for at least six weeks.

Physical therapy of the ankle joint will be recommended by the doctor. After 2-3 months of therapy, the patient may be able to perform their normal daily activities.

Risks and complications

Risks and complications that can occur with ankle fractures include improper casting or improper alignment of the bones which can cause deformities and eventually arthritis. In some cases, pressure exerted on the nerves can cause nerve damage, resulting in severe pain.

Rarely, surgery may result in incomplete healing of the fracture, which requires another surgery to repair.

The foot has 26 bones, and can be divided into 3 parts:

• The hind foot is comprised of two bones, the talus bone which connects to the bones of the lower leg, and the calcaneus bone which forms the heel.
• The midfoot is comprised of the navicular, cuboid, and three cuneiform bones.
• The forefoot is made up of five metatarsal bones and 14 toe bones called phalanges.

The hind foot is separated from the midfoot by the mediotarsal joint and the midfoot is separated from the forefoot by the lisfranc joint. Muscles, tendons and ligaments support the bones and joints of the feet enabling them to withstand the entire body’s weight while walking, running and jumping. Despite this, trauma and stress can cause fractures in the foot. Extreme force is required to fracture the bones in the hind foot. The most common type of foot fracture is a stress fracture, which occurs when repeated activities produce small cracks in the bones.

Types of foot fractures

Foot fractures can involve different bones and joints and are classified into several types:

• Calcaneal fractures: This type affects the heel bone and occurs mostly as a result of high-energy collisions. It can cause disabling injuries and if the subtalar joint is involved it is considered a severe fracture.
• Talar fractures: The talus bone helps to transfer weight and forces across the joint. Talus fractures usually occur at the neck or mid portion of the talus.
• Navicular fractures: Navicular fractures are rare and include mostly stress fractures that occur with sports activities, such as running and gymnastics, as a result of repeated loading on the foot.
• Lisfranc fractures: This type of fracture occurs due to excessive loading on the foot, which leads to stretching or tearing of the midfoot ligaments.

Causes

Foot fractures commonly occur as a result of a fall, motor vehicle accident, dropping a heavy object on your foot, or from overuse such as with sports.

Symptoms

The common symptoms of a foot fracture include pain, bruising, tenderness, swelling, deformity and inability to bear weight.

Diagnosis

Your doctor diagnoses a foot fracture by reviewing your medical history and performing a thorough physical examination of your foot. Imaging tests such as X-rays, MRI or CT scan may be ordered to confirm the diagnosis. Navicular fractures can be especially difficult to diagnose without imaging tests.

Treatment

Treatment depends on the type of fracture sustained. For mild fractures, nonsurgical treatment is advised and includes rest, ice, compression, and elevation of the foot. Your doctor may suggest a splint or cast to immobilize the foot. For more severe fractures, surgery will be required to align, reconstruct or fuse the joints. Bone fragments may be held together with plates and screws.

Physical therapy may be recommended to improve range of motion and strengthen the foot muscles. Weight bearing however should be a gradual process with the help of a cane or walking boot.

The calcaneus or heel bone is a large bone found on the rear part of the foot. The calcaneus connects with the talus and cuboid bones to form the subtalar joint of the foot. A fracture is a break in a bone from trauma or various disease conditions. The types of fracture to the calcaneus depend on the severity and include stable fractures, displaced fractures, open fractures, closed fractures and comminuted fractures.

A fracture of the calcaneus is most commonly due to a traumatic event such as falling from a height, twisting injury, motor accidents, sports injuries and ankle sprain.

Fracture of the calcaneus is considered serious and can cause longstanding problems if not treated correctly. Stiffness and pain in the joint and arthritis are commonly reported risks of a calcaneal fracture.

The commonly seen signs and symptoms of calcaneal fractures are

• Pain in the heel
• Swelling in the heel
• Bruises in the heel
• Inability to walk or bear weight on the foot

The evaluation of the calcaneal fracture is done by imaging i.e., X-ray and CT scan. Based on the severity of the fracture, the doctor recommends the plan of treatment.

Calcaneal fractures are treated based on the type of fracture and extent of soft tissue damage.

• Nonsurgical treatment
• Rest, ice, compression, and elevation (R.I.C.E.) – is the most commonly used treatment option. Staying off (resting) the injured foot can heal the fracture to a great extent. Covering the affected area with ice packs over a towel reduces swelling and pain. Compression stockings and elastic bandages can also aid in healing the pain. Positioning the feet above the level of heart reduces swelling.
• Immobilization – Casting the injured foot prevents the fractured bone from moving. Walking with the help of crutches is advisable to avoid bearing body weight until healing has occurred.
• Surgical treatment
• Open reduction and internal fixation – This surgery involves putting the bone fragments back together with metal plates and screws to reposition them and set them to normal alignment.
• Percutaneous screw fixation – This is the best preferred treatment in cases where the bone pieces are large. The bone can either be pushed or pulled to set into place without making a large incision. Metal screws are then inserted and fixed through small incisions to hold the bone pieces together.

Rehabilitation

Irrespective of the treatment procedure, the patient is recommended to undergo physiotherapy and practice simple exercises regularly to help restore function. This would help the muscles to gain flexibility and after complete recovery, the patient can resume their daily living with normal activities.

Tarsometatarsal joint refers to the region found in the middle of the foot. It is also called as Lisfranc joints. It is a junction between the tarsal bones (group of seven articulating bones in the foot) and metatarsal bones (a group of five long bones in the foot). A deformity in the tarsometatarsal region can be due to arthritis and traumatic motor accidents.

Tarsometatarsal arthritis is characterized by pain, functional impairment and midfoot instability. The appearance of bruises and swelling on the dorsal side of the midfoot are the commonly observed symptoms. The doctor will first examine the physical condition of the foot by inspection and palpation (feeling with hands). You may be advised to get an X-ray taken. You might also be sent to get a CT or MRI scan done to provide more information about your condition.

The early stages of injury can be treated by analgesics, steroid injections and by wearing special footwear or casts. Tarsometatarsal joint fusion is recommended if all the non-surgical procedures fail to show efficacy in treating the injury.

A stress fracture is described as a small crack in the bone which occurs from an overuse injury of a bone. It commonly develops in the weight bearing bones of the lower leg and foot. When the muscles of the foot are overworked or stressed, they are unable to absorb the stress and when this happens the muscles transfer the stress to the bone which results in stress fracture.

Stress fractures are caused by a rapid increase in the intensity of exercise. They can also be caused by impact on a hard surface, improper footwear, and increased physical activity. Athletes participating in certain sports such as basketball, tennis or gymnastics are at a greater risk of developing stress fractures. During these sports, the repetitive stress of the foot strike on a hard surface causing trauma and muscle fatigue. An athlete with inadequate rest between workouts can also develop stress fracture.

Females are at a greater risk of developing stress fracture than males, and may be related to a condition referred to as “female athlete triad”. It is a combination of eating disorders, amenorrhea (irregular menstrual cycle), and osteoporosis (thinning of the bones). The risk of developing stress fracture increases in females if the bone weight decreases.

The most common symptom is pain in the foot which usually gets worse during exercises and decreases upon resting. Swelling, bruising, and tenderness may also occur at a specific point.

Your doctor will diagnosis the condition after discussing symptoms and risk factors and examines the foot and ankle. Some of the diagnostic tests such as X-ray, MRI scan or bone scan may be required to confirm the fracture.

Treatment

Stress fractures can be treated by non-surgical approach which includes rest and limiting the physical activities that involves foot and ankle. If children return too quickly to the activity that has caused stress fracture, it may lead to chronic problems such as harder-to-heal stress fractures. Re-injury can also occur without allowing the stress fracture to completely heal.

Protective footwear may be recommended which helps to reduce stress on the foot. Your doctor may apply cast to the foot to immobilize the leg which also helps to remove the stress. Crutches may be used to prevent the weight of the foot until the stress fracture is healed completely.

Surgery may be required if the fracture is not healed completely by non-surgical treatment. Your doctor makes an incision on the foot and uses internal fixators such as wires, pins, or plates to attach the broken bones of the foot together until healing happens after which these fixators can be removed or may be permanently left inside the body.

Some of the following measures may help to prevent stress fractures:

• Ensure to start any new sport activity slowly and progress gradually
• Cross-training: You may use more than one exercise with the same intention to prevent injury. For example, you may run on even days and ride a bike on odd days, instead of running every day to reduce the risk of injury from overuse. This limits the stress occurring on specific muscles as different activities use muscles in different ways.
• Ensure to maintain a healthy diet and include calcium and vitamin D-rich foods in your diet
• Ensure that your child uses proper footwear or shoes for any sports activity and avoid using old or worn out shoes
• If your child complains of pain and swelling then immediately stop the activities and make sure that your child rests for few days

The talus is a small bone at the ankle joint that connects the heel bone and the two bones of the lower leg, enabling the up and down movement of the foot. Fractures in the talus bone may occur due to a fall from great heights, motor vehicle accidents or twisting of the ankle. The symptoms include severe ankle pain, inability to walk, swelling and tenderness.

When you present to the clinic with these symptoms, your doctor will perform a thorough physical examination and order an X-ray or CT-scan to diagnose the location and severity of the fracture. Talus fractures are treated by either non-surgical or surgical methods.

Non-surgical treatment: If the bone has not moved out of alignment, your doctor will place your ankle in a cast for 6 to 8 weeks. You will be advised to perform exercises to help strengthen your foot and ankle and restore range of motion once the cast is removed.

Surgical treatment: Your surgeon realigns the fractured bone and stabilizes it with metal plates and/or screws. Small bone fragments may be removed and replaced with bone graft. After surgery, you may have to wear a cast for 6 to 8 weeks until complete healing. Physical therapy exercises will be initiated to restore movement.

The forefoot is the front of the foot that includes the toes. Fractures occurring in this part of the foot are painful but very often not disabling. There are 2 types of fractures namely, traumatic fracture and stress fracture. Traumatic fractures occur when there is a direct impact of your foot on a hard surface. Stress fractures are tiny hair line cracks in the bone, most commonly caused due to repeated stress. The symptoms of toe and forefoot fractures include pain, bruising, swelling and inability to walk.

To detect toe and forefoot fractures, your doctor conducts a physical examination of the foot, and may order X-ray’s to identify the location and severity of the fracture. Toe and forefoot fractures can be treated by the following ways:

• Rest: Adequate amount of rest can sometimes help heal a traumatic fracture.
• Splinting: Splints may be applied to keep the toe in a fixed position.
• Rigid shoe: A stiff-soled shoe may be recommended to protect the toe and position it correctly.
• Buddy taping: The fractured toe is taped to the adjacent toe with a gauze pad between the toes.
• Surgery: Your doctor realigns the fractured bones using pins or screws to hold the bones together in place until they heal completely.

The hip joint is a "ball and socket" joint. The "ball" is the head of the femur or thigh bone and the "socket" is the cup shaped acetabulum. The joint surface is covered by a smooth articular surface that allows pain free movement in the joint.

Hip fracture is a break that occurs near the hip in the upper part of the femur or thigh bone. The thigh bone has two bony processes on the upper part - the greater and lesser trochanters. The lesser trochanter projects from the base of the femoral neck on the back of the thigh bone. Hip fractures can occur either due to a break in the femoral neck, in the area between the greater and lesser trochanter or below the lesser trochanter.
Hip fracture is most frequently caused after minor trauma in elderly patients with weak bones, and by a high-energy trauma or serious injuries in young people. Long term use of certain medicines, such as bisphosphonates to treat osteoporosis (a disease causing weak bones) and other bone diseases, increases the risk of hip fractures.

Signs and symptoms of hip fracture include

• Pain in the groin or outer upper thigh
• Swelling and tenderness
• Discomfort while rotating the hip
• Shortening of the injured leg
• Outward or inward turning of the foot and knee of the injured leg

Your doctor may order an X-ray to diagnose your hip fracture. Other imaging tests, such as the magnetic resonance imaging or (MRI), may also be performed to detect the fracture.

Depending on the area of the upper femur involved, hip fractures are classified as

• Intracapsular Fracture
• Intertrochanteric Fracture
• Subtrochanteric Fracture

Hip fractures can be corrected and aligned with non-operative and operative methods:

Traction may be an option to treat your condition if you are not fit for surgery. Skeletal traction may be applied under local anesthesia, where screws, pins and wires inserted into the femur and a pulley system is set up at the end of the bed to bear heavy weights. These heavy weights help in correcting the misaligned bones until the injury heals.

Hip fractures can be surgically treated with external fixation, intramedullary fixation, or by using plates and screws.

Pelvic fracture is a condition that arises due to breakage of the pelvis bones. It may damage internal organs, nerves, and blood vessels associated with the pelvis region.

The pelvis is a round structure of bones located at the base of the spine, connected to the sacrum of the spine with the help of strong ligaments. The pelvis is composed of three bones, namely ilium, ischium, and pubis that are fused together. The side of the pelvis is composed of a cup shape socket, known as acetabulum.

Various organs related to the digestive and reproductive systems lie within the pelvis ring. Also, several large nerves and blood vessels supplying the lower limbs pass through the pelvis. The pelvis ring also acts as point of attachment for muscles approaching from the upper and lower part of the body.

Based on the damage of the pelvis ring and associated structures, pelvic fractures can be categorized as:

• Stable pelvic fractures: Have single point breakage in the pelvis ring and broken bones remain in position; shows less bleeding
• Unstable pelvic fractures: Have breakage at two or more points, followed by severe bleeding. Unstable pelvic fractures may cause shock, extensive internal bleeding, and damage to the internal organs. It requires immediate medical care followed by long-term physical therapy and rehabilitation.

Causes

The common causes responsible for pelvic fractures include:

• Sports injuries or trauma
• Abrupt muscle contraction
• Conditions such as osteoporosis, especially in elderly people
• Accidental injury or fall from a great height

Symptoms

The common symptoms associated with pelvic fractures are:

• Pain and swelling in the groin or hip region that may worsen with ambulation
• Abdominal pain
• Bleeding through the urethra or vagina and the rectum
• Problems in urination
• Unable to stand or walk

Diagnosis

The diagnosis of pelvic fracture starts with physical examination including checking the functional activity of the various body organs present in the pelvic region. Imaging techniques such as X-rays, CT (Contrast Tomography) and MRI (Magnetic Resonance Imaging) scan may also be used to confirm the exact condition or breakage of the pelvic bones. In some cases, additional contrasting studies using radioactive dye may be recommended to evaluate the structural and functional activity of organs such as the urethra, bladder, and the pelvic blood vessels.

Treatment

Treatment of the pelvic fracture depends upon the severity of the injury and condition of the patient. Minor or stable fractures can be treated with conservative methods such as rest, medications, use of crutches, physical therapy, and if required minor surgery. These methods may take 8-12 months for complete healing.

The treatment of unstable fractures includes management of the bleeding and injuries of the internal organs, blood vessels, and nerves. Surgical intervention may be employed for fixation of the fractured pelvic bones using screws and plates. Pelvic bone fixation provides stability to the pelvic bone and promotes natural healing of the fracture.

The tibia or shin bone is a major bone of the leg which connects the knee to the ankle. A tibial fracture is a break in the continuity of the shin bone (tibia).

Fractures of proximal tibia: A proximal tibial fracture is a break in the upper part of the shin bone or tibia. Proximal tibial fractures may or may not involve the knee joint. Fractures that enter the knee joint may cause joint imperfections, irregular joint surfaces, and improper alignment in the legs. This can lead to as joint instability, arthritis, and loss of motion. These fractures are caused by stress or trauma or in a bone already compromised by disease, such as cancer or infection. Proximal tibia fractures can result in injury to the surrounding soft tissues including skin, muscle, nerves, blood vessels, and ligaments.

The symptoms of tibia fracture include painful weight bearing movements, tenseness around the knee, limitation of movement and deformity around the knee. In some individuals, impairment of blood supply secondary to the fracture may result in a pale or cool foot. Patients may also experience numbness or feelings of ‘pins and needles' in the foot as a result of associated nerve injury.

The diagnosis of tibial fracture is based on the medical history including history of any previous injuries, complete physical examination and imaging studies. The physician will evaluate a soft tissue around the joint to identify any signs of nerve or blood vessel injury. Multiple X-rays and other imaging studies such as CT and MRI scans may be used to identify the location and severity of the fracture.

The management of the fracture is based on the severity of the fracture, medical condition of the patient and the patient's lifestyle.

Non-surgical treatment comprises of immobilizing the fractured site with the help of casts or braces to prevent weight bearing and to help the healing process. X-rays are taken at regular intervals to assess the healing process. Weight bearing and movement are initiated gradually, depending on the nature of the injury and the condition of the patient.

Surgical treatment is considered to maintain alignment of the fractured bone. External or internal fixators may be used to align the fractured bone segments. If the fracture does not involve the knee joint, rods and plates can be used to stabilize the fracture. For a fracture involving the knee joint, a bone graft may be required to prevent the knee joint from collapsing. An external fixator is used when the surrounding soft tissue is severely damaged, as the use of plate and screw may be harmful.

As the tibial fracture usually involves the weight bearing joint it may cause long term problems such as loss of knee motion or instability and long term arthritis. Hence a rehabilitation program is initiated along with the treatment comprising of instructions on weight bearing, knee movements, and the use of external devices such as braces.

The femur or thighbone is the largest and strongest bone in the human body. Pediatric thighbone fractures can occur when your child falls hard on the ground and gets hit during sports, automobile accidents, and child abuse. In a thighbone fracture, the broken bones may be aligned or displaced. The fracture can either be closed (with skin intact) or open (with the bone piercing out through the skin). Your child may experience severe pain, swelling, inability to stand and walk, and limited range of motion of hip or knee.

Your child's doctor will conduct a physical examination. An X-ray or CT-scan may be recommended to locate the position and number of fractures, and determine if the growth plate is damaged. Femur fractures may be treated with non-surgical or surgical methods.

Non-surgical treatment involves stabilizing the bones so they can heal and fuse together. Braces, spica casting (cast applied from the chest, down the fractured leg) or traction (placing the leg in a weight system) may be used to ensure that the bones are properly set in their normal position.

Surgery is recommended for complicated injuries. Your child's surgeon aligns the broken bones and uses metal plates and screws to hold the fractured bones together in proper alignment. Your child may have to wear a cast for a few weeks until complete healing. An external fixator may be used in case of open injury to the skin and muscles.

The tibia or shin bone is a major bone of the leg which connects the knee to the ankle. A tibial fracture is a break in the continuity of the shin bone (tibia).

Types

• Fractures of proximal tibia: A proximal tibial fracture is a break in the upper part of the shin bone or tibia. Proximal tibial fractures may or may not involve the knee joint. Fractures that enter the knee joint may cause joint imperfections, irregular joint surfaces, and improper alignment in the legs. This can lead to as joint instability, arthritis, and loss of motion. These fractures are caused by stress or trauma or in a bone already compromised by disease, such as cancer or infection. Proximal tibia fractures can result in injury to the surrounding soft tissues including skin, muscle, nerves, blood vessels, and ligaments.
• Tibial shaft fractures: A tibial shaft fracture is a break that occurs along the length of the tibia or shin bone (larger bone of the lower leg) between the knee and ankle joints. These fractures can occur while playing sports such as soccer and skiing.

The symptoms of tibia fracture include painful weight bearing movements, tenseness around the knee, limitation of movement and deformity around the knee. In some individuals, impairment of blood supply secondary to the fracture may result in a pale or cool foot. Patients may also experience numbness or feelings of ‘pins and needles' in the foot as a result of associated nerve injury.

The diagnosis of tibial fracture is based on the medical history including history of any previous injuries, complete physical examination and imaging studies. The physician will evaluate a soft tissue around the joint to identify any signs of nerve or blood vessel injury. Multiple X-rays and other imaging studies such as CT and MRI scans may be used to identify the location and severity of the fracture.

Hence a rehabilitation program is initiated along with the treatment comprising of instructions on weight bearing, knee movements, and the use of external devices such as braces.

The femur or thigh bone is the longest and strongest bone in the body, connecting the hip to the knee. A femur fracture is a break in the femur. The distal femur is the lower part of the thigh bone which flares out like an upside-down funnel and its lower end is covered by a smooth, slippery articular cartilage that protects and cushions the bone during movement. Fracture of the distal femur may involve the cartilaginous surface of the knee as well and result in arthritis.

Types

• Distal femurfracture: The distal femur ispart of the femur bone that flares out like the mouth of the funnel.A distal femur (top part of knee joint) fracture is a break inthighbone that occurs just above your knee joint.
• Femoralshaft fracture: A femoral shaftfracture is a break that occurs anywhere along the femoral shaft,long, straight part of the femur.
• Proximalfemur fracture: A hip fracture orproximal femur fracture is a break in the proximal end of the thighbone near the hip.

Femur fractures may be caused by high energy injuries such as a fall from height or a motor vehicle accident. Patients with osteoporosis, bone tumor or infections, or a history of knee replacement are more prone to femur fractures. In the elderly, even a simple fall from a standing position may result in a fracture as the bones tend to become weak and fragile with advancing age.

Sudden, severe pain along with swelling and bruising are the predominant symptoms of femur fracture. The site is tender to touch with a visible physical deformity and shortening of the leg.

The diagnosis of femur fracture is based on the patient's medical history including history of any previous injuries, complete physical examination and imaging studies. The physician will evaluate the soft tissue around the joint to identify any signs of nerve or blood vessel injury. Multiple X-rays and other imaging studies such as CT and MRI scans may be used to identify the location and severity of the fracture.

The management of the fracture is based on the severity of the fracture, medical condition of the patient and the patient's lifestyle.

Non-surgical treatment comprises of immobilizing the fractured site with the help of casts or braces to prevent weight bearing and to help the healing process. X-rays are taken at regular intervals to assess the healing process. Weight bearing and movement are initiated gradually, depending on the nature of the injury and the condition of the patient.

Surgical treatment is considered to realign the fractured bone. The use of advanced technology and special materials has improved the surgical outcome even in older patients. External or internal fixation or a knee replacement may be required depending on the extent of the fracture. Timing of the surgery is an important factor in improving the surgical outcome.

Timing of surgery

In most cases, the surgery is delayed for a few days to develop an effective treatment plan and for preparation of the patient. With most distal femur fractures the surgery can be delayed unless the fracture is open to the environment.

External fixator

An external fixator is used when the surrounding soft tissue is severely damaged, as the use of plates and screws may be harmful. The external fixator maintains the alignment of the bone till surgery.

Once the patient is prepared for surgery, the surgeon removes the external fixator and places internal fixation devices into the bone during surgery.

Internal fixator

The internal fixation may be performed using intramedullary nailing or plates and screws. In intramedullary nailing a metal rod is inserted into the marrow canal of the femur to keep the fractured fragment in position. In the plate and screw method the bone fragments are realigned and held together with screws and plates, attached to the outer surface of the bone. If the fracture is of the comminuted type or the bone has broken into many pieces, plates or rods may be used at the ends of the fracture without disturbing the smaller pieces. The plate or rod will maintain the shape or strength of the bone till it heals. In elderly patients and those with poor bone quality, bone grafting may be used to improve the healing. Knee replacement may also be considered in complicated fractures or those with poor bone quality.

Knee replacement

Artificial implants may be used to replace the fractured segments of the bone and joint.

Rehabilitation

Rehabilitation of the femur fracture depends upon several factors such as age, general health of the patient and the type of fracture. As the femur fracture usually involves the weight bearing joint it may cause long term problems such as loss of knee motion or instability and long term arthritis. Hence a rehabilitation program is initiated along with the treatment comprising of instructions on weight bearing, knee movements, and the use of external devices such as braces.
