Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic medical treatment, in particular to a fixing device for femoral fractures. Background Art

[0002] The shapes of bones in different parts of the human body are different and their structures are complex. If injuries such as fractures occur, medical treatment and rehabilitation usually require appropriate treatment based on the bone structure of the injured part. When the fracture is close to the joint, it is less suitable to use plaster fixation, so devices and bone screws are usually used as fixators to treat fractures.

[0003] Among them, the femur, as the main weight-bearing bone of the lower limbs, plays a vital role in supporting body weight and movement. The incidence of femoral fractures is relatively high. Once a fracture occurs under external impact, different treatments will be given according to the severity of the fracture. If the femoral fracture is accompanied by displacement of fracture fragments or ends, comminuted fractures, joint deformities, etc., surgical treatment should be chosen.

[0004] Therefore, a fixation system for femoral fractures is proposed, which can stably maintain the reduction state of the femoral fracture site to better promote the healing of the fracture site, prevent excessive sliding and pressure at the femoral fracture site, fix the inner support rod to prevent it from falling off and moving, and adjust the device according to different heights and angles of the inner support rod, thereby avoiding shortening of the femoral neck after the fracture site heals, and ensuring that the hip abduction function of the human body is not affected after the fracture site heals.
