Arthroscopic minimally invasive treatment of gluteal myoclonusFu Zhihou, Department of Orthopaedic Diseases, Jinan General Hospital, Jinan Military RegionGeneral HospitalGluteal myoclonus, also known as frog’s leg, has been treated with traditional incisional release surgery, which is highly traumatic and has many complications. From January 2006 to January 2011, 56 patients with gluteal myoclonus were treated with minimally invasive arthroscopic radiofrequency vaporization, and were followed up for 6 to 28 months (average 18 months) after the operation. Results: The 56 patients were evaluated by gait, squatting with knees together, crossed-leg test, and effect on movement, of which 51 were excellent, 4 were good, and 1 was acceptable. No recurrence of symptoms was found during the follow-up period, and the patients’ self-satisfaction rate was 10 0%. Conclusion: Arthroscopic radiofrequency vaporization can satisfactorily treat gluteal myoclonus with little trauma, quick recovery, and aesthetics, and the incision is only 3 mm. Positive preoperative crossed-legs test, negative postoperative crossed-legs test, and postoperative incision.
