Intramedullary nailing is a surgical procedure used to repair a broken bone and keep it stable. It involves inserting a permanent nail or rod into the centre of the bone, with the aim of preserving the anatomical structure of the fracture site and providing an environment conducive to healing. The femur, or thigh bone, is the largest bone in the human body, and fractures of the femoral shaft are a common occurrence in orthopedic practice. The healing time for femoral shaft fractures treated with unreamed IM nailing varies, with an average healing time of around 19 weeks. The choice between long and short nails for treating femoral fractures is controversial, as the use of long nails can increase surgical time and blood loss.

Femur IM nailing is a surgery to repair a broken bone
Intramedullary nailing is often used to treat fractures of the thigh bone, or femur, which is the largest bone in the body. Femoral shaft fractures, which occur in the long middle section of the femur, are serious injuries that can result in short-term disability, pain, and a high risk of long-term deformity. Intramedullary nailing can also be used to treat fractures of the tibia, hip, shin, upper arm, and other long bones.
The surgery typically requires only a few small incisions in the skin, although larger incisions may be necessary in severe fractures to realign the bones properly. After the bone is aligned, the surgeon inserts the intramedullary nail through the centre of the bone, running from the hip to the knee in the case of the femur. Locking screws are placed on both ends of the nail to keep it in place, and the incisions are closed with stitches or staples.
Following surgery, patients typically stay in the hospital for 1-2 days, although this can vary depending on the patient's needs. During this time, patients will experience swelling and pain in the affected leg, which can be managed with medication. It is important to begin walking with crutches or another support device as soon as possible, usually within a day of surgery, to prevent blood clots and promote weight-bearing, which is important for bone strengthening.
The recovery process after intramedullary nailing involves physical therapy and exercises to restore range of motion and rebuild muscle strength. X-rays are taken at regular intervals to monitor the healing process and ensure the bone is healing properly. In most cases, the intramedullary nail does not need to be removed, and it can remain in place for life. However, in some cases, it may be removed after a year or more if there is irritation of soft tissues or other complications.

The procedure involves inserting a nail or rod into the centre of the bone
Intramedullary nailing is a surgical procedure used to repair a broken bone and keep it stable. It involves inserting a nail or rod, typically made from medical-grade materials, into the centre of the bone. This technique is commonly performed on the thigh, shin, hip, and upper arm bones.
The procedure begins with the patient placed supine on a radiolucent fracture table. Fluoroscopy, a type of medical imaging, is used to assess the appropriate length and position of the nail in relation to the fractured bone. This preoperative step is crucial for ensuring the correct placement of the nail during surgery.
Once the nail length and position are determined, the surgeon will make an incision and insert the nail into the centre of the bone. Locking screws are then placed on both ends of the nail to secure it in place. The incision is closed with stitches or staples, and the patient is typically encouraged to walk around on the same day or the day after surgery to prevent blood clots and promote weight-bearing.
The benefits of intramedullary nailing include preserving the anatomical structure of the fracture site, limiting damage to surrounding soft tissues, and providing a proper environment for fracture healing. It offers a high rate of union and a low risk of malunion. However, there are also risks associated with the procedure, such as pain, discomfort, and the possibility of mechanical failure or bending of the implant.
The healing time for femoral shaft fractures treated with unreamed intramedullary nailing is approximately 19.36 weeks, with an overall healing rate of 93.6%. The average length of hospital stay for these procedures is around 15.5 days.

The patient must not eat or drink anything after midnight on the day of surgery
Intramedullary nailing is a surgical procedure used to repair a broken bone and keep it stable. The femur, or thigh bone, is the largest bone in the body, and fractures in its shaft or diaphysis (the long, straight middle section) are usually the result of high-energy trauma, such as road traffic accidents.
The surgery involves inserting a permanent nail or rod into the centre of the bone. This helps to provide stability and allows the patient to put weight on the bone, which is important for strengthening it. The patient will need to walk around on the day of the surgery or the day after to prevent blood clots and aid in bone strengthening.
To prepare for the surgery, patients must not eat or drink anything after midnight on the day of the procedure. They will be given specific instructions by their surgeon on which medications to take or avoid. During the surgery, the patient will receive an antibiotic through an IV to prevent bacterial infections.
The surgical technique for intramedullary nailing of the femur involves obtaining a freehand lock before performing standard outrigger locking. This allows the surgeon to control the nail and deliver the locking hole to a unicortical drill hole in the femur. The distance of the desired locking hole is measured before nail insertion to ensure accuracy. Through the unicortical drill hole, a Kirschner wire is used to palpate the nail and manoeuvred to fall into the locking hole. The wire is then tapped across the second cortex before drilling and inserting the screw. The screw position is confirmed by passing an insertion guidewire up the nail to impact the locking screw. Rotation and length are then confirmed, and proximal screws are placed.
The "box" technique is a specific method used for the extracreorporeal measurement of femoral nail length in the treatment of trochanteric hip fractures. This technique involves obtaining fluoroscopic images to assess the appropriate nail length before surgery. The images are obtained after the patient is intubated, positioned on the fracture table, and reduced. Typically, 2-3 anteroposterior images are obtained to align the proximal end of the packaged nail over the proximal femur, followed by 1-2 images of the distal end. The "box" technique has an accuracy of 95.2% in its femoral length-spanning predictions and is considered safe and reliable for choosing the appropriate nail length.

The patient may experience swelling and pain post-surgery
Intramedullary nailing is a surgical procedure used to repair a broken bone and keep it stable. The femur, or thigh bone, is the largest bone in the human body, and fractures of the femoral shaft often result in short-term disability and pain, with a high risk of long-term deformity and disability.
To aid recovery, a physical therapist may recommend exercises to strengthen leg muscles and keep joints flexible. A pressure stocking may also be used to increase blood flow and prevent blood clots. This is a long, tight stocking that applies pressure to the legs, promoting blood flow out of the lower leg veins. Additionally, blood-thinning medication may be prescribed to further reduce the risk of clots.
In some cases, patients may experience persistent pain that interferes with their lifestyle or mobility. This pain may be related to heterotopic ossification, which is the formation of bone in soft tissue rather than in bone tissue. In such cases, implant removal may be considered, although this does not always cure the pain.

The healing time for femur IM nailing is around 19-20 weeks
Intramedullary nailing is a surgical procedure used to repair a broken bone and keep it stable. The femur, or thigh bone, is the largest bone in the body and fractures are usually the result of high-energy trauma, such as road traffic accidents. The healing time for femur IM nailing is around 19-20 weeks, with a high rate of union and a low rate of infection and malunion.
The surgery involves inserting a permanent nail or rod into the centre of the bone to keep the nail and bone in the proper position during healing. This procedure helps to preserve the anatomical structure of the fracture site and provide an environment conducive to fracture healing. It also limits damage to the surrounding soft tissues and helps preserve blood supply, thereby improving function and reducing long-term complications such as pain from arthritis.
After surgery, patients may experience swelling and pain in their leg, which is normal and should subside within a few days. Walking around on the day of or the day after surgery is important to prevent blood clots and promote weight-bearing, which strengthens the bone. Physical therapy may also be recommended to aid in leg healing and muscle strengthening.
The timing of surgery depends on the nature of the fracture. Open fractures, where the bone is exposed, require immediate treatment to prevent infection. In some cases, external fixation with metal screws or pins may be necessary to provide temporary stability before the final surgery, which can extend the overall recovery time.
Overall, the healing time for femur IM nailing can vary, but generally falls within the range of 19 to 20 weeks, with most patients requiring specialised treatment in a long-term rehabilitation facility.
