[Treatment of ischemic necrosis of the femoral head by transplantation of pedicled bone flap with deep iliac circumflex vessel].

OBJECTIVE

To investigate the treatment method of ischemic necrosis of the femoral head by the transplantation of pedicled bone flap with deep iliac circumflex vessel in adult and to assess its curative effect.

METHODS

From February 1996 to September 2003, 46 adult patients with ischemic necrosis of the femoral head (58 coxas) were treated by transplantation of pedicled bone flap with deep iliac circumflex vessel. The locations were the left side in 34 coxas and the right side in 24 coxas(stage II in 16 coxas, stage III in 39 coxas and stage IV in 3 coxas).

RESULTS

Thirty-seven patients (40 coxas) were followed up 6 months to 10 years after operation. According to the assess of FanQishen, the result was excellent in 19 cases (21 coxas), good in 11 cases (12 coxas), fair in 5 cases (5 coxas) and poor in 2 cases (2 coxas). The postoperative excellent and good rate was 81%.

CONCLUSION

Operative treatment of ischemic necrosis of the femoral head in adult by transplantation of bone flap pedicled with deep iliac circumflex vessel has the characteristics of restoration of blood supply of the femoral head, decompression of marrow cavity, elimination of necrotic bone and support of the femoral head. It is an effective and advanced method for treatment of ischemic necrosis of the femoral head in adult.
