There are several complications of femoral head fracture surgery in the elderly: firstly, the most common complication is traumatic arthritis. Since femoral head fracture is a fracture involving the articular surface, it will cause damage to the articular surface, and articular cartilage is non-renewable cartilage, so once a femoral head fracture is formed, it will lead to the formation of traumatic arthritis. Secondly, femoral head fractures in the elderly, even after surgical treatment, can easily lead to delayed healing of the fracture, or even non-healing. Because the elderly usually have osteoporosis, the bone is in a state of loss, so it is more difficult to heal after the fracture. Finally, femoral head fractures in the elderly are particularly likely to lead to the formation of femoral head necrosis after surgery, and the chances of this occurring are quite high.
