Intramedullary nailing is a common surgery used to repair broken bones and keep them stable. A metal nail is surgically inserted into the centre of the bone to straighten and hold fractures so they can heal. The nail may be removed if there is irritation of soft tissues, pain, or infection. However, the outcome after nail removal is unpredictable and may even cause additional pain. There are also several complications associated with the removal of intramedullary nails, such as re-fracture, failed attempts at nail removal, and long operating times.

Anterior knee pain is the main reason for removal
Intramedullary nails are small rod-like devices inserted into the hollow centre of a bone, known as the medullary cavity. They are used to stabilise fractures by acting as an internal splint. They are commonly used to treat fractures of the tibia, femur, and humerus.
Anterior knee pain is a common complication following intramedullary nailing, particularly of the tibia. This pain is believed to be caused by the irritation of the patella tendon and the fat pad in the knee joint by the implant. The exact cause of anterior knee pain is not known, but it is thought to be influenced by the surgical approach and location of the nail. The pain can also be caused by pathologies that cannot be seen on X-rays or during surgery, such as injuries to the ligaments, bone, or cartilage of the knee joint.
Given the high incidence of anterior knee pain following intramedullary nailing, it is not surprising that this is the main reason for the removal of the nail. However, the outcome of nail removal to alleviate pain is unpredictable, and the procedure may even initiate anterior knee pain. A study by Shaodong Zhang et al. found that out of 71 patients who underwent nail removal, 39 experienced relief from anterior knee pain, 18 had increased pain, and 4 were unsatisfied with the outcome. Another study of 72 patients by Toivanen et al. found that 27 (38%) complained of chronic anterior knee pain, with 21 of these patients experiencing sensory deficits in the infrapatellar nerve distribution area.
While intramedullary nail removal is generally considered a minor and low-risk procedure, it is not without complications. In addition to the risk of persistent or new-onset anterior knee pain, complications such as re-fracture, failed attempts at nail removal, long operating times, and wound infection have been reported. Therefore, the decision to remove an intramedullary nail should be carefully considered, and patients should be informed that their pain may persist or even worsen following the procedure.

Routine removal is encouraged to prevent stress shielding
Intramedullary nailing is a common surgery done in orthopaedics to repair a broken bone and keep it stable. The most common bones fixed by this procedure are the thigh, shin, hip, and upper arm. A permanent nail or rod is placed into the centre of the bone to straighten and hold fractures so that they can heal properly.
Routine removal of intramedullary nails has been encouraged to prevent stress shielding. However, one study found similar stress shielding in patients whether their intramedullary nails had been retained or removed. Another reason for routine nail removal is to avoid difficult future revision surgery in cases of refracture.
The removal of an intramedullary nail is generally regarded as a minor, low-risk procedure with little morbidity. However, it can be challenging and may not always receive the desired preoperative planning, operative expertise, and staff support. Anterior knee pain is the main reason for the removal of the nail. However, the outcome after nail removal to alleviate pain is unpredictable, and the procedure may even initiate anterior knee pain.
A retrospective study of 71 patients who had undergone tibial nail removal found that 39 patients had less pain after removal, 14 had unaltered pain, and 18 had increased pain. Another study of 48 patients who had undergone tibia nail removal found that 43 (89.58%) tibial intramedullary nails were removed over a period of 5 years. The nail may also be removed if there is irritation of soft tissues or infection.

Removal is a minor, low-risk procedure
Intramedullary nailing is a common surgery done in orthopaedics to repair a broken bone and keep it stable. The procedure involves surgically inserting a metal nail into the centre of a fractured bone to straighten and hold the fracture so that it can heal properly. The nail may be permanent, but it is sometimes removed.
Removal of an intramedullary nail is commonly regarded as a minor, low-risk procedure with little morbidity. There are few reports of complications associated with the removal of intramedullary nails. However, it can be a challenging task that does not always receive the desired preoperative planning, operative expertise, and staff support.
Anterior knee pain is the main reason for the removal of an intramedullary nail. However, the outcome after nail removal to alleviate pain is unpredictable, and the procedure may even initiate anterior knee pain. Other reasons for removal include infection and hardware failure.
In a study of 100 cases of lower limb intramedullary nail removal, 12 femoral and 25 tibial nails were removed for pain, and 4 tibial nails were removed for infection. There were 3 operative complications, 2 abandoned procedures, and 1 tibial fracture. In 9 out of 16 cases, anterior knee pain improved after tibial nail removal, but 4 patients who were previously asymptomatic developed anterior knee pain following the procedure.
Another study of 71 patients who underwent tibial nail removal found that 39 patients had less pain after removal, 14 patients had unaltered pain, and 18 patients had increased pain. The results of nail removal to alleviate pain are poor, and removal should not be undertaken unless there is a convincing indication.

Removal can be challenging and may lead to complications
Intramedullary nailing is a common surgery done in orthopaedics to repair a broken bone and keep it stable. It is usually done for fractures of the tibia, femur, and humerus. The nail may be removed if there is irritation of soft tissues, to alleviate pain, to eradicate infection, or to solve hardware failure.
However, removal can be challenging and may lead to complications. While it is commonly regarded as a minor, low-risk procedure, there are some challenges and risks associated with the removal of intramedullary nails. One study found that out of 71 patients who underwent tibial intramedullary nail removal, only 39 experienced reduced pain after the procedure. 14 patients had unaltered pain levels, and 18 patients experienced increased pain. The study concluded that the results of nail removal to alleviate pain are poor and that removal should not be undertaken without a convincing indication.
Another study investigated the outcome of 100 cases of lower limb intramedullary nail removal. Of these, 12 femoral and 25 tibial nails were removed due to pain, and 4 tibial nails were removed due to infection. There were 3 operative complications, 2 abandoned procedures, and 1 tibial fracture. The study concluded that all complications were avoidable and that intramedullary nail removal is safe. However, it is important to note that 4 patients who previously had no symptoms developed anterior knee pain following the procedure.
One reason why intramedullary nail removal can be challenging is that the bone may heal in an abnormal position, with the ends of the fracture not joining correctly. This can affect the stability of the bone and increase the risk of refracture during the removal procedure. In addition, the nail or rod used may bend or fail, requiring additional surgery. There is also a risk of damage to nerves or blood vessels, which can cause temporary or permanent numbness in the affected leg.
Overall, while intramedullary nail removal is generally considered a safe and low-risk procedure, there are potential challenges and complications that can arise. It is important for patients to be aware of these risks and for surgeons to carefully evaluate each case to determine if removal is necessary and to ensure the best possible outcome.

Removal may be done to eradicate infection
Intramedullary nails are small rod-like devices inserted into the medullary cavity of a fractured bone to stabilize it. They are often used to treat fractures of the tibia, femur, and humerus. While intramedullary nailing is widely accepted as a safe and effective treatment for tibial shaft fractures, there is some controversy regarding the indications for nail removal.
In some cases, intramedullary nails may be removed to eradicate infection. Infection at the site of the fracture or implant is a serious complication that can lead to prolonged healing times and increased pain. If infection is suspected, it is crucial to address it promptly to prevent further complications.
According to a study on the outcome of 100 cases of lower limb intramedullary nail removal, 4 tibial nails were removed due to infection. While this number may seem small, it is important to recognize that infection can have severe consequences if left untreated.
The decision to remove an intramedullary nail due to infection is a complex one. While the removal of the nail can help eradicate the infection, it is also important to consider the potential risks and complications associated with the procedure. These may include refracture, failed attempts at nail removal, long operating times, persistent anterior knee pain, and wound infection.
Furthermore, it is worth noting that the presence of an intramedullary nail itself may not be the direct cause of infection. Other factors, such as the fracture, surgical procedure, or post-operative care, may contribute to the development of an infection. Therefore, a comprehensive assessment is necessary to determine the source of the infection and implement appropriate treatment measures.
