Hip and pelvic fractures and sciatic nerve injury / 中华创伤杂志(英文版)

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the influence of hip and pelvic fracture, especially acetabular fracture complicated by sciatic nerve injury on clinical features and prognosis of sciatic nerve injury.</p><p><b>METHODS</b>From January 1987 to January 2000, 17 patients (14 male and 3 female) who had hip and pelvic fractures complicated by sciatic nerve injury were treated with operative reduction and internal fixation and followed up from 10 months to 5 years. The average age was 38 years (ranging 23-56 years). The left extremities were involved in 11 patients and the right in 6. Twelve patients underwent primary exploration and neurolysis and 5 patients underwent secondary operation.</p><p><b>RESULTS</b>Preoperatively, 8 patients were treated with large doses of oral narcotics to control their severe sciatic pain. Three of the 8 patients underwent patient-controlled analgesia and epidural analgesia. After operation, excellent and good rates of reduction and functional recovery of sciatic nerve were 94.1% and 88% respectively. Four patients still had sciatic pain and 2 patients failed to recover. Sciatic nerve function improved within 3-6 months after surgery in 11 patients.</p><p><b>CONCLUSIONS</b>Hip and pelvic fractures can result in sciatic nerve injury, especially common peroneal nerve injury and prognosis is poor. Open reduction and internal fixation combined with nerve exploration and neurolysis should be used as early as possible for severe sciatic pain.</p>
