Acetabular dysplasia refers to the development of the process, due to acetabular defects caused by the development of the acetabulum on the femoral head coverage is bad, the acetabulum becomes shallow, hip joint center shift. Because of the abnormal relationship between the acetabulum and the femoral joint, the contact stress of the articular surface is increased, and the articular cartilage degeneration and secondary cause osteoarthritis.
More than 45 years old female friends, male and female ratio of about 1:5.
The disease sometimes does not show hip pain, but the pain of the knee, when the development of hip pain until the end of the period, which is easy to missed diagnosis or misdiagnosis reasons.
The treatment of acetabular dysplasia and aims to correct the acetabular deformity and restore acetabular hyaline cartilage coverage, increase hip bearing area, normal biomechanical reconstruction of the hip joint, reduce the occurrence and development of osteoarthritis.
According to the different degree of acetabular dysplasia deformity, surgery can be divided into the reconstruction of the osteotomy and salvage osteotomy two.
Reconstruction of osteotomy for early osteoarthritis of the hip joint surgery, the restoration of near normal acetabular anatomy and hyaline cartilage covering.
If osteoarthritis has been close to late, you can only choose a salvage osteotomy or artificial joint replacement surgery.
At present, the reconstructive surgery for acetabular dysplasia in adults with acetabular rotation osteotomy and acetabular osteotomy, two kinds of surgery can achieve good clinical results.
On behalf of the surgical salvage pelvic osteotomy is rotational acetabular osteotomy in our department, the acetabular osteotomy of the femoral head and acetabular rotation to improve tolerance, thus reducing the contact stress, relieve pain and improve joint stability, gait, delayed artificial joint replacement time, while providing good coverage for the artificial acetabulum joint replacement in the future.
Total hip arthroplasty is the only effective method for the treatment of patients with advanced osteoarthritis.
