[Impacting bone graft via surgical hip dislocation approach versus core decompression and bone graft for avascular necrosis of femoral head at ARCO stage Ⅲ].

OBJECTIVE: To compare the effectiveness of sequestrum clearance and impacting bone graft via surgical hip dislocation approach and core decompression and bone graft for avascular necrosis of the femoral head (ANFH) at Association Research Circulation Osseous (ARCO) stage Ⅲ. METHODS: >0.05). After operation, the function of the hip was evaluated by Harris hip score, imaging examination was performed to observe the femoral head shape and evaluate whether the hip preserving success. RESULTS: =0.456). In group A, greater trochanter bone cutting were healed well; and the heterotopic ossification around the hip joint occurred in 1 case. CONCLUSION: The surgery of impacting bone graft via surgical hip dislocation approach and core decompression and bone graft can be applied to treat ANFH at ARCO stage ⅢA which was mild collapse and satisfactory effectiveness can be obtained. While for the patients of ANFH at ARCO stage Ⅲ B with severe collapse, the hip survival rate of the former is better than that of the latter.
