Abstract: Objective To analyze the pathogenesis of the complications of gluteal muscle contracture (GMC) in adults and provide basis for the management of complications. Methods The clinical data and pathogenesis of the complications of type C1 GMC in 1 000 adult patients were analyzed retrospectively. Results ① 1 000 patients suffered from varying degrees of greater trochanteric bursitis, gluteal myofascitis and lumbar back myofascitis, and these complications disappeared after receiving the minimally invasive procedure method invented by Prof. Ye and 6-8 weeks of clinical rehabilitation. ② 762 patients suffered from varying degrees of wear-and-tear arthritis of the knee joint; 168 suffered from varying degrees of wear-and-tear arthritis of hip joint; 12 patients suffered from varying degrees of wear-and-tear arthritis of ankle joint. The arthritis pain and activity limitations disappeared after the minimally invasive procedure method and 6-8 weeks of clinical rehabilitation. The snapping sound of joints did not disappear, but had not developed. ③ 586 patients suffered from varying degrees of pelvic obliquity, leg length discrepancy and scoliosis. These conditions were cured after receiving the minimally invasive procedure and 6-10 weeks of clinical rehabilitation. ④ Three patients suffered from bilateral aseptic necrosis of femoral head; 329 patients suffered from varying degrees of lumbar disc herniation. ⑤ 560 patients were with depression tendency, Hamilton Depression Scale (HDC) score was 12.9±4.1; 182 patients suffered from depression, with HDC score of 21.4±2.6; 6 patients suffered from severe depression, with HDC score over 24. Their depression disappeared after receiving the minimally invasive procedure and 6-10 weeks of clinical rehabilitation. Conclusions The complications of AGMC can be classified as two categories: reversible complications and irreversible complications. The minimally invasive procedure method and clinical rehabilitation technique invented by Prof. Ye can cure reversible complications. It can stop or control the development of irreversible complications, but cannot correct the damage which already occurred. The early surgery and clinical rehabilitation are very important for treating AGMC in order to reduce and ease the irreversible complications.
