In clinical practice, it is conventional to remove the internal fixation after a calf fracture in about 1-1/2 years, but the prerequisite is that the fracture must heal completely, the fracture line must disappear, and there must be no abnormalities in ambulation before the internal fixation can be removed. If fracture healing is delayed and the fracture line is still present, it is not permissible to remove the internal fixation at this time. Once the internal fixation is removed prematurely, it is very easy to displace the fracture and form a secondary fracture. Of course, some patients will heal relatively early due to their age and blood supply, and the internal fixation can be removed even after six months, but some patients have a significant delay in fracture healing due to individual factors, and the fracture is not completely healed 1 or 2 years after surgery.
