526GLUTEUS MINIMUS MUSCLE: LESS INVASIVE POSTERIOR APPROACH FOR THE SURGICAL MANAGEMENT OF POSTERIOR WALL ACETABULUM FRACTUREThe Posterior wall acetabulum fractures are the most common acetabulum fracture. Most of this fracture requires surgical intervention. Less invasion treatment planning, choice of suitable surgical approach, minimal injury to the soft tissue, muscles, nerves and blood vessels, anatomical reduction maneuvers and surgical fixations are most important for best surgical reconstruction. The aim of our study is less invasive posterior approach, small incision, minimal bluntly splitting of gluteus minimus muscle, less soft tissue and muscle injury, less blood vessels injury; to give the patient rigid fixation and functional hip minimizing the complication and fixation in short periods. So that, the postoperative mobilization of the patient could be faster than other traditional posterior approach. According to our study, the outcome of less invasive path of surgical approach is better for early mobilization of the patient, less chances of infection, due to early post operative mobilization there will be less chances of early complication like DVT, bed sores, pulmonary embolism, and pneumonia and late complications like post traumatic osteoarthritis, avascular necrosis and heterotopic ossification. The aim of our approach is to give the patient rigid fixation and functional hip, minimizing the complication.zn-taoshengxiang@163.comResearch6112016Posterior wall acetabular fracture, Gluteus minimus muscles,Less invasive posterior approach,Cadaveric data studyNiresh Shrestha,Hu Xiang,Tao Sheng XiangDepartment of Orthopedic Surgery, Zhongnan Hospital of Wuhan University, 169 Donghu Road, Wuchang District, Wuhan, 430071, Hubei, People’s Republic Of China,Department of Orthopedic Surgery, Zhongnan Hospital of Wuhan University, 169 Donghu Road, Wuchang District, Wuhan, 430071, Hubei, People’s Republic Of China,Department of Orthopedic Surgery, Zhongnan Hospital of Wuhan University, 169 Donghu Road, Wuchang District, Wuhan, 430071, Hubei, People’s Republic Of China
