Comminuted hip fractures are certainly more serious, and their severity is mainly reflected in the following aspects: first, there are rich muscles and strong ligaments around the hip joint, and only under the effect of obvious external injury or great violence will a comminuted hip fracture occur, and there is a long recovery time for comminuted fractures, which has a great impact on the function of the hip joint, and there may be muscle atrophy around the hip joint and The problem of weakening of the lower limb strength. Secondly, fractures involving the acetabulum or femoral head and femoral neck are prone to complications such as non-union of the fracture and necrosis of the femoral head. Third, comminuted fractures lead to unevenness of the joint surface, and sequelae such as traumatic arthritis can occur. The two sequelae of the latter surgery can only be solved by total hip replacement surgery.
