Abstract:

BACKGROUND: Currently, there are many methods for treatment of adult non-invasive femoral head necrosis, but their long-term efficacy is not sure.
OBJECTIVE: To evaluate the clinical efficacy of gluteus medius bone grafting with vascular pedicle combined with bone morphogenetic protein and autogenous cancellous bone for non-traumatic osteonecrosis of the femoral head. 
METHODS: Sixty-nine patients (83 hips) with non-traumatic osteonecrosis of the femoral head underwent thorough curettage and gluteus medius bone grafting with vascular pedicle combined with bone morphogenetic protein and autogenous cancellous bone. Defects in the femoral neck were implanted with gluteal muscle flap from the greater trochanter without fixation. After treatment, anteroposterior X-ray films of the hip were regularly reviewed.
RESULTS AND CONCLUSION: All the patients were followed up successfully for 12-120 months (average 48 months). The pain of the hip in all patients disappeared or mostly relieved after the operation. The motion of hip joint became better. According to the score of 100 points recommended by Chinese Medical Association, the surgical outcomes were excellent in 48 hips (58%), good in 27 hips (33%), fair in 6 hips (7%), and poor in 2 hips (2%). The good rate was 90%. The gluteus medius bone grafting with vascular pedicle combined with bone morphogenetic protein and autogenous cancellous bone for non-traumatic osteonecrosis of the femoral head can obtain mini-trauma, better recovery of necrotic bone and excellent clinical results. However, the long-term effects need further studies.
