Shortening of the femoral neck in femoral neck fractures is generally normal, but pathology cannot be ruled out.
Internal fixation of femoral neck fracture may result in a shortening of a part of the length, which is normal.
However, there are also pathological factors leading to femoral neck shortening, such as poor femoral head repositioning, hip osteoarthritis and rheumatoid arthritis.
1. When the femoral head is poorly reset, atrophy of the femoral neck is likely to occur, leading to shortening of the femoral neck.
2. Osteoarthritis of hip joint: this kind of disease is a kind of chronic aseptic inflammation caused by degenerative disease of articular cartilage, which usually leads to narrowing of joint space and shortening of femoral neck.
3. Rheumatoid or rheumatoid arthritis: These diseases can also lead to atrophy and shortening of the femoral neck.
There may be other causes of femoral neck shortening. When femoral neck shortening occurs, it is recommended to consult a doctor in time, complete relevant examinations, and carry out targeted treatment after clarifying the cause of the disease.
