内固定物是否应该取出（Should the implant be removed） Should the implant be removed? Liu Zhi Traditionally, fixtures are usually removed. The removal of internal fixation accounted for about 29% of the elective surgery in the Department of orthopedics, accounting for 6% [1] of all department of orthopedics operations. Since 1990s, there has been a lot of discussion about whether or not an internal fixture should be removed. Internal fixation surgery has some risks, including local hematoma, infection, fracture, nerve injury, internal fixation remains not taken, the complication rate in 3%20% between [2, 3], which has obvious effects on the human body overall complication rate should be less than 5%, including nerve injury, deep infection and re fracture. However, the risk of re fracture is relatively high after the removal of the fracture of the distal forearm and lower femur. The rate of re fracture can be as high as over 10% [4, 5, 6], which should be paid enough attention to. Generally speaking, the removal of the internal fixation is a simple and safe operation [2, 7], which is also a consensus among the general clinicians. But it is precisely this notion that, to some extent, ignores the potential risk of removal of the internal fixation. Potential risks may be magnified, especially if professional qualifications are inadequate or surgical procedures are performed by a junior physician. It has been reported that severe neurologic injuries are mostly performed by the less skilled physicians (3). Internal fixation operation requires skills and experience, preoperative risk judgement, such as the forearm and femur fracture plate were higher incidence [4, 5, 6], the risk of proximal humerus and radius of plate were nerve injury is relatively large. Re fracture after internal fixation is one of the most striking problems. The common risk factors mainly include 3 aspects, one is the anatomical factors, and forearm fracture after internal fixation of femoral and fracture risk is
