Gluteal myoclonus syndrome is often a clinical syndrome in which the gluteal muscle and its fascial fibers degenerate and contracture, resulting in limited hip function, caused by repeated multiple gluteal injections in early childhood. These patients have depressions, lumps, or fascicular bands in the buttocks and a popping or snapping sensation in the hips. The patient walks with an obvious “external eight” and cannot “cross his legs”. In the light cases, the knees are separated when squatting, and then come together after squatting (circle sign). In severe cases, the patient can only squat in the adductor and adductor position, and the heel of the foot does not land on the ground, showing a frog-like pattern. For most patients with gluteal myoclonus, West China Hospital uses gluteal myoclonic band amputation: the surgical incision is only about 3cm, less traumatic, and the patient can be discharged from the hospital the next day after the operation. For patients with severe contracture, our hospital uses gluteal contracture band cutting and gluteus maximus stop point release, which can fully solve the causative factors, and the curative effect is satisfactory. Postoperative functional exercise: after contracture release, the contracture may recur due to gluteus maximus re-adhesion, therefore, postoperative functional exercise is needed to prevent the re-adhesion of the severed end of the superficial broad fascia tensor fasciae latae iliotibialis bundle.
