Femoral head bone grafting surgery

Femoral head necrosis is a problem that troubles many people, and it is also a common disease in clinical practice. For the problem of femoral head necrosis, surgical treatment is generally adopted when drug treatment is ineffective, and femoral head bone grafting surgery is also a type of surgery targeted at treating femoral head necrosis. There are many things that patients need to pay attention to before and after femoral head bone grafting surgery.

1. When placing the femoral head, please note that: the artificial femoral head must be kept at a slight valgus of 130° to 140° and a 15° anteversion. The base of the prosthesis neck should be parallel and close to the cross-section of the femoral neck. Do not use excessive force when driving the femoral head. If there is resistance, check the direction carefully to avoid penetrating the cortical bone. One thing that must be pointed out is that the soft tissue around the artificial hip joint should be of appropriate tightness (with normal tension). If it is too tight, it will easily wear the acetabulum, while if it is too loose, it will be unstable and easily damage the acetabulum. This is also closely related to the choice of prosthesis neck length and placement position.

2. Femoral head necrosis, also known as avascular necrosis of the femoral head, is one of the common bone and joint diseases. This disease first destroys the blood supply to the adjacent joint surface tissue, which then causes necrosis. Its main symptoms develop from intermittent pain to continuous pain, which then causes muscle spasms and restricted joint movement, and finally causes severe disability and lameness. Femoral head necrosis can occur at any age, but is most common between the ages of 31 and 60, with no gender difference.

3. Immediately after the operation, the unfixed joints should be moved, muscle contraction exercises should be performed, and lower limb massage should be performed to prevent deep vein thrombosis. The patient can sit up after 2 to 3 days, and gradually increase the active and passive range of motion; the stitches will be removed 10 days after the operation; the patient can walk with crutches 3 to 4 weeks after the operation, and should walk with crutches for protection within half a year. The exercise process can be supplemented with physical therapy. After abandoning the crutches, care should still be taken to avoid excessive activity and injury. If pain, local inflammation, etc. occur, timely follow-up treatment should be given.
