[Transposition of muscular skeletal flap pedicled with straight head of rectus femoris for treatment of avascular necrosis of femoral head].
OBJECTIVE
To investigate the clinical results of transposition of muscular skeletal flap pedicled with straight head of rectus femoris for treatment of avascular necrosis of adult femoral head.


METHODS
Eight patients with avascular necrosis of femoral head were adopted in this study. There were 6 males and 2 females, the ages were ranged from 24 to 56 years. According to the criteria of Ficat, there were 5 cases in stage II and 3 cases in stage III. The Smith-Peterson incision was used to expose the capsule of the hip. After complete curettage of the necrotic bone from the femoral head, the muscular skeletal flap pedicled with straight head of rectus femoris was resected and transposited into femoral head. Finally, conventional decompression of head was performed.


RESULTS
All the cases were followed up for 1 to 3 years. There were excellent results in 5 cases, good in 2 cases and moderate in 1 case. The rate of excellent and good results were 87.5%.


CONCLUSIONS
Comparing with other pedicled bony flaps, the muscular skeletal flap pedicled with straight head of rectus femoris is characterized by its convenience and efficacy. It is suitable for the treatment of avascular necrosis of femoral head in stage II or III, but the contour of the femoral head should be nearly normal.
