The recovery time after femur intertrochanteric fracture surgery is about 3 months, the exact recovery time is related to the patient’s own recovery, bone quality and other factors. The healing of intertrochanteric fracture needs to go through 3 periods, i.e. hematoma inflammation mechanization period, primitive bone scab formation period, and bone scab reforming and shaping period. 1. Hematoma inflammation mechanization period: due to the fracture of intertrochanteric femur, the local bone continuity is destroyed, and at the same time, the muscles, blood vessels and other soft tissues around the fracture end are damaged, forming a local aseptic inflammatory reaction, and with the exudation of inflammatory factors, the affected area manifests as pain and swelling. 2. Primary bone scab formation period: about 1 month after surgery, the fracture end forms a fibrous primary bone scab, and the fracture is initially connected. At this time, the local inflammatory reaction of the affected area has mostly subsided, but the patient may still be accompanied by pain and other discomforts during activities. 3. Scab transformation and shaping period: about 3 months after the operation, the fibrous scab gradually transforms and shapes into a bony scab, and the femoral trochanter recovers completely, at this time, the patient will not have pain symptoms when he/she normally carries weight or walks with exercise. The specific recovery time after femur intertrochanteric fracture surgery is related to the patient’s own recovery, bone quality and other factors. It is recommended that patients listen to the advice of specialists and actively cooperate with doctors to carry out various therapeutic activities.
