Abstract:
OBJECTIVETo study clinical efficacy of autologous bone graft for acetabular defect of Crowe III and IV hip dysplasia.
METHODSThe 22 patients with 25 hips of DDH (Crowe type III, IV) from March 2010 to May 2013 were retrospectively analyzed. Total hip arthroplasty (THA) combined autogenous bone grafting was performed for all these patients with osteoarthritis secondary to DDH. Among them, 19 patients were females (21 hips) and 3 patients were males (4 hips), ranging in age from 43 to 67 years old, averaged 55 years old. There were 6 hips with Crowe type III and 19 hips with Crowe type IV. Before surgery, all the patients had hip pain, limb shortening and hip limited function of hip joint. After 12 months, the degree of recovery about limb length, functional recovery, autogenous bone graft fusion were observed.
RESULTSAll the patients were followed up and no dislocation were occurred. At 12 months after operation, the average Harris hip joint llzncation score were 83.30±6.13, and 18 cases got an excellent result and 4 good. The length of lower limbs decreased from preoperative (3.20±0.81) cm to 12 months after operation (0.92±0.23) cm (t=14.864, P<0.05).
CONCLUSIONTHA combined with structural femoral head autograft for patients with osteoarthritis secondary to DDH can obtain favorable results, significantly improving the effect of operation treatment.
