Intramedullary nailing is a surgical procedure used to treat bone fractures, particularly in long bones such as the femur or thigh bone. It involves inserting a metal rod, known as an intramedullary nail, into the medullary cavity of the fractured bone to provide stability and support during the healing process. This technique aims to preserve the anatomical structure of the fracture site, promote proper healing, and reduce long-term complications. The procedure is considered the gold standard for treating femoral shaft fractures and has been continuously refined with advancements in technology, dating back to early descriptions by Aztec physicians in the 16th century.

Intramedullary nailing is a surgery to repair a broken bone and keep it stable
Intramedullary nailing is a surgical procedure used to repair a broken bone and stabilise it. It involves inserting a metal rod (or nail) into the medullary cavity of a bone, providing solid support for the fractured bone. This procedure is often used for fractures in the thigh, shin, hip, and upper arm.
During the surgery, small incisions are made in the skin, and a guidewire is threaded into the centre of the bone. A device may be used to hollow out the bone, after which the surgeon lines up the broken ends. The nail is then inserted into the hollow part of the bone, keeping the broken ends aligned. Locking screws are placed on both ends of the nail to keep it in place, and the incisions are closed with stitches or staples.
Intramedullary nailing is considered the "gold standard" for treating femoral shaft fractures. It offers several advantages, including a shorter hospital stay, rapid union of the fracture, and early functional use of the limb. The technique also minimises soft tissue irritation and helps preserve the anatomical structure of the fracture site, providing a proper environment for healing.
There are different types of intramedullary nails and techniques available, such as antegrade and retrograde nailing, and the use of reaming or interlocking nails. The choice of technique depends on the specific fracture pattern and patient needs.
After the surgery, patients may experience swelling and pain in the 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 strengthen the bone through weight-bearing. Patients may also require physical therapy to restore their range of motion and rebuild muscle strength.

Intramedullary nailing is a surgical procedure used to repair a broken bone and keep it stable. It involves inserting a metal rod, or nail, into the medullary cavity of a bone. This procedure is often used for fractures of the long bones, such as the thigh, shin, hip, and upper arm.
During the operation, the surgeon will make small incisions in the skin and thread a guidewire into the centre of the bone. They may use a device to hollow out the bone, creating space for the nail. The nail is then inserted into the hollow part of the bone, lining up the broken ends and keeping them in place. Locking screws are placed at both ends of the nail for added stability. The incisions are then closed with stitches or staples.
Intramedullary nailing is considered the "gold standard" for treating femoral shaft fractures, as it provides solid support for the fractured bone. It offers several advantages over other methods, including a shorter hospital stay, faster healing, and early functional use of the limb. The procedure also helps preserve the anatomical structure of the fracture site, providing a proper environment for healing and reducing long-term complications such as arthritis pain.
After the surgery, patients may experience swelling and pain in the operated limb, which is normal and typically improves within a few days with medication. Walking as soon as possible after surgery is important to prevent blood clots and promote weight-bearing, which strengthens the bone. X-rays will be taken periodically to monitor the healing process, and physical therapy will be recommended to restore the range of motion and rebuild muscle strength. In most cases, the intramedullary nail remains in place for about a year, after which it may be removed in an outpatient procedure.

It is considered the gold standard for treating femoral shaft fractures
Intramedullary nailing is a surgical procedure used to treat femoral shaft fractures. It involves inserting a metal rod (intramedullary nail) into the medullary cavity of a bone across the fracture to provide solid support for the fractured bone. This procedure is considered the gold standard for treating femoral shaft fractures due to its effectiveness in stabilising the fracture and reducing complications and mortality.
Several studies have indicated that early surgical stabilisation of femoral shaft fractures is crucial in reducing potential complications and improving patient outcomes. Intramedullary nailing provides this stability by acting as an internal splint, allowing the bone fragments to heal in the correct position. The procedure also helps preserve the anatomical structure of the fracture site, providing an optimal environment for healing and reducing the risk of long-term complications such as arthritis and deformity.
The intramedullary nail can be inserted using different techniques, including retrograde nailing and antegrade nailing. In retrograde nailing, the nail is inserted into the canal at the knee and pushed up towards the hip, while in antegrade nailing, the nail is inserted at the hip and pushed down towards the knee. The choice between these techniques depends on various factors, including the patient's anatomy, associated injuries, and surgeon preference.
Intramedullary nailing also offers several advantages over other treatment methods. It typically requires a shorter hospital stay, allows for rapid union of the fracture, and enables early functional use of the limb. The procedure is usually performed through small incisions, reducing the risk of infection and other complications. Additionally, the use of locking screws at both ends of the nail provides stability and reduces the risk of hardware failure.
While intramedullary nailing is considered the gold standard, it is important to note that there are potential risks and complications associated with any surgical procedure. These include infection, nerve damage, abnormal fracture healing, and hardware failure. Therefore, a comprehensive evaluation by an orthopedic surgeon is essential to determine the most appropriate treatment approach for each individual patient.

The technique can be used to treat other types of fractures, such as olecranon and tibial nonunion fractures
Intramedullary nailing is a surgical procedure where a metal rod is inserted into the medullary cavity of a bone to provide support for a fracture. It is considered the "gold standard" for treating femoral shaft fractures, and can also be used to treat other types of fractures, such as olecranon and tibial nonunion fractures.
Olecranon fractures are proximal ulnar fractures that commonly occur and often require surgical fixation. Tension banding and dorsal olecranon plates are commonly used to treat these fractures, but they often require a secondary procedure for hardware removal due to soft-tissue irritation. Intramedullary olecranon nailing is an effective treatment option that may reduce soft-tissue irritation. The procedure involves positioning the patient to allow improved access to the fracture, reducing the fracture, reaming the olecranon, inserting the intramedullary nail, placing proximal interlocking screws, and closing the wound. Union was achieved in all patients treated with intramedullary olecranon nailing in one series, with an average healing time of eight weeks.
Intramedullary nailing is also used to treat tibial shaft fractures in adults. While it is a common practice, complications and subsequent surgeries are frequent. Anterior knee pain is the most common complication, affecting one-in-five patients, followed by non-union, which occurs in 11% of patients. Other complications include abnormal fracture healing, bending or failure of the nail or rod, nerve or blood vessel damage, and irritation in the area where screws were placed.
To prevent complications, it is important to systematically review the available evidence and compare different categories and methods of intramedullary nailing, such as insertion portal/approach, nailing technique, and type of nail. Patient-rated functional outcome measures and health-related quality of life measures can also be used to assess the effectiveness of the treatment.

Potential complications include infection, abnormal fracture healing, and nerve or blood vessel damage
Intramedullary nailing is a surgical procedure used to treat femoral shaft fractures in adults. It involves inserting a metal rod, known as an intramedullary nail, into the medullary cavity of a bone across the fracture site. This provides solid support and aids in the healing process. While intramedullary nailing is considered the "gold standard" for treating femoral shaft fractures, potential complications can arise, including infection, abnormal fracture healing, nerve damage, and blood vessel damage.
Infection is a potential complication, especially in low-income countries where the risk may be higher. Postoperative infections can be superficial, involving only the skin, or deep, affecting the bone and/or implant. The presence of open fractures, where the bone is exposed, further increases the risk of wound infection and contamination. Additionally, non-union, or the absence of healing at the expected time, is a risk factor for infection and can lead to increased operating time.
Abnormal fracture healing can occur, resulting in long-term deformity and disability. This may be influenced by the type of intramedullary nail used, such as interlocking nails or Ender nails, and the insertion technique, such as retrograde or antegrade nailing. Antegrade nailing, for example, carries a higher risk of hip complications, including heterotopic ossification, pudendal nerve injury, and residual pain.
Nerve damage is another potential complication of intramedullary nailing. A case study involving pediatric patients reported temporary radial nerve damage following flexible intramedullary nailing. The radial nerve's motor branch was affected, resulting in posterior interosseous nerve palsy and wrist drop.
Lastly, blood vessel damage can occur during intramedullary nailing, particularly during the reaming of the intramedullary canal. This can lead to blood loss and an increased risk of blood transfusion within the first 48 hours post-operatively.

Frequently asked questions
Intramedullary nailing is a surgical procedure used to stabilise and treat bone fractures. It involves inserting a metal rod, or nail, into the medullary cavity of a bone to provide solid support for the fractured bone.
Intramedullary nailing is considered the "gold standard" for treating femoral shaft fractures as it offers several advantages over other treatments. These include a shorter hospital stay, faster healing, and early functional use of the limb. It also minimises soft-tissue irritation and may result in less gapping at the fracture site.
During the surgery, the patient is usually put under general anaesthesia. The surgeon makes a small incision near the fractured bone and inserts a guidewire into the centre of the bone. A device may be used to hollow out the bone, and then the nail is inserted into the hollow part to align the broken ends. Locking screws are placed on both ends to secure the nail, and the incision is closed with stitches or staples.
After the surgery, the patient is encouraged to walk around as soon as the day of the surgery or the following day to prevent blood clots and promote weight-bearing. Deep breathing exercises are also recommended to open the airway and reduce the risk of lung infection. The surgeon will take X-rays regularly to monitor the healing process and determine when the nail can be removed, which is usually after a year.
