Purpose: This study analyzed the postoperative complications in a series of unstable pelvic bone fractures treated surgically.
Material and Methods: 49 cases treated by operative treatment in unstable pelvic fractures from June 1994, to June 2001 were retrospectively reviewed. The radiological results were evaluated according to the residual displacement and leg length discrepancy. The clinical results were evaluated according to the level of pain and functional disabilities, and the postoperative complications were analyzed.
Results: The average of anterior pelvic ring displacement improved from a mean preoperative value of 30mm(8~87 mm), to a mean postoperative value of 6 mm(0~24 mm), that of the posterior pelvic ring displacement improved from 16 mm(0~56 mm), to 4 mm(0~30 mm). The average leg length discrepancy of 17.7 mm(0~60 mm)
preoperatively, decreased to 3.4 mm(0~30 mm) postoperatively. Three cases had moderate pain and 3 cases had a moderate limping. Postoperative complications of the anterior pelvis included infection(1 case), malunion(2 cases), and fixation failure(4 cases). The postoperative complications of the posterior pelvis included infection(1 case), malunion (2 cases), and fixation failure(1 case). Fatigue fracture of the plate(4 cases) and the 5th lumbar nerve injuries(2 cases) did not affect the final outcome.
Conclusions: It is recommend that the precise surgical technique and appropriate approach are essential. In addition, an anatomical reduction should be made in unstable pelvic bone fractures in order to minimize the postoperative complications associated with the surgical treatment.
