Abstract:
Objective To evaluate the results of gluteal muscle contracture released by radiofrequency vaporization (RF) under arthroscopic guidance. Methods Eighteen cases of bilateral gluteal muscle contracture were treated with radiofrequency vaporization. The patients consisted of 7 males and 11 females, aging from 8 to 40 years. The patients were lying in lateral recumbent position under epidural anesthesia. The outline of the gluteal contracture, the incision line and the sciatic nerve were marked preoperatively on the skin. The entrance for the vaporization was 2 cm superior and 5 cm lateral to the top of the greater trochanter. The portal for the arthroscope was 3 cm inferior to the antero-superior iliac spine. A space was made between constricted fibrous band and overlying subcutaneous tissue with an elevator, and then saline was filled into the space, the constricted fibrous band from the tip of the greater trochanter was removed. The contracture was released, bleedings were controlled, and the range of motion of the hip was evaluated, it was guaranteed that the motions like snapping and impingement were eliminated completely. The patients were allowed to walk about 24 hours following operation in order to prevent adhesions. Results All of the cases of bilateral gluteus contracture treated with RF vaporization were followed up for average 7 months (range, 6 to 13 months). Two cases of hematoma were noted, there was no infection, no limitation in squatting, no snapping, and no difficulty in crossing the legs. Ober sign was negative in the treated patients. The gait and function recovered to normal. Conclusion Gluteus contracture can be effectively released with RF vaporization under arthroscopic guidance. The advantages of this procedure are mild tissue damage and reaction, and less blood loss. The tissue damage is very limited. The rehabilitation can be started soon postoperatively, and functional recovery is better.
