Objective To explore the therapeutic effect of total hip arthroplasty (THA) and hip adductor amputation (HAA) in the surgical treatment of osteonecrosis of femoral head. Methods A total of 74 patients with osteonecrosis of femoral head with hip adduction deformity were included between June 2011 and May 2012. Among them, 38 patients had undergone THA, and 36 patients had undergone THA+HAA. Statistics about hip abductor function and Harris scores before and 1 week and 12 months after the surgery were recorded. SPSS 19.0 was used for statistical analysis. Results The patients' wounds had the Ⅰ-stage healing in both of the two groups. Two patients had scrotum swelling in THA+HAA group, who left the hospital after treating. One week after the surgery, the hip passive abduction angles increased (32.1±2.8) and (19.7±3.3)°, respectively in the THA+HAA group and THA group, while the Harris hip score increased 45.8±2.8 and 40.9±2.3, respectively; 12 months postoperatively, the hip passive abduction angles increased (32.2±0.9) and (26.8±2.8)°, respectively in the THA+HAA group and THA group, while the Harris hip score increased 52.7±7.2 and 49.4±4.4, respectively. The above comparative differences was statistically significant (P<0.05). Conclusion The surgical method of adductor amputation can improve the range of motion of the hip, raise the quality of life of the patients with osteonecrosis of the femoral head after the surgery.
