[Advances in Diagnosis and Treatment of Posterior Distal Injury of Pelvic Fracture].

Pelvic fracture is one of the common diseases of traumatic orthopedics. With the increase of accidents such as traffic accidents,high craters and crush injuries in China,the incidence of pelvic fractures is also increasing year by year. Since pelvic bones and the ligament structure are close to neurovascular,cavity organs and the urogenital structure,early diagnosis and treatment of pelvic fractures is essential for preventing early complications and late sequelae. The treatment of pelvic ring injury has been the focus of pelvic fracture treatment,which determines the outcome of treatment. The application of external fixation and internal fixation to pelvic fracture is still subject to ongoing debate. For unstable pelvic ring injury,emergency external fixation plays a very important role. Pelvic ring injury is often accompanied with nerve injury (lumbosacral plexus injury),which often leads to pain,dysfunction and other complications. Because of its refractory,extensive studies have been undertaken to identify clinical innovations that may be able to repair nerve damage and reduce complications. These research advances can help improve the diagnosis and treatment of pelvic fractures and patient survival and prognosis.
