The Basic And Clinical Study Of Modified Operational Mode In Gluteal Muscle Contracture

Objective: According to the local dissection of gluteus maximus and the pathological dissection of gluteal muscle contracture to discuss the modified operational mode and attention" s proceeding of the operation. Methods: ㏕o anatomize 6 cases 12 sides buttocks specimen and to observe the original spot, nourishing vessel, innervation of gluteus maximus and relations with sciatic nerve; ㏕o observe the local pathological changes of 67 cases gluteal muscle contracture. 〢ccording to the above results, to design syncline S-shaped incision on the posterior and upper part of the big tuberosity of femur to treat 56 cases gluteal muscle contracture which compared with those selected other incisions. Results: ㏕he start point and the stop point of gluteus maximus are far-ranging while the cases" pathological changes only restrained in gluteus fascia and gluteus maximus fibre. (2)The enter points of the nourishing vessels and nerves of gluteus maximus are between the upper and the below quarter. (3)There is clearance between gluteus maximus and deep muscles which full of fat. connective tissue, blood vessels and nerves, the sciatic nerve is situated the groove which between thighbone's big tuberosity and ischial tuberosity and has honeycomb tissue with gluteus maximus. ㏕he operational time, bleeding, the fissions of incision and sinuses formation which used modified S-shaped incision are reduced than before remarkably. Conclusion: (D.The modified S-shaped incision will be a better choice in the operation of gluteal muscle contracture. (D.In order to avoid the injury of blood vessels and nerves, the incision should be located to the middle muscle and along with the fiber's way. (3).If close with thighbone's big tuberosity and attended it's groove at the same time could avoid the injury of sciatic nerve.
