ObjectiveTo retrospectively analyze the patients of vertically unstable pelvic fractures treated with percutaneous iliosacral screws fixation and to explore the operative techniques and its therapeutic efficacy.MethodsFrom June 2002 to August 2009, 54 patients with vertical unstable pelvic fracture were fixed with percutaneous iliosacral screws. After operation, 46 patients were followed up more than 18 months. Among them, 32 patients were male and 14 patients were female, the average age was 36.4 years old (ranged from 19 to 64 years). The average time from injury to operation was 8.5 days (ranged from 7 to 11 days). All pelvic fractures had vertical dislocation ranging from 8 to 40 mm (averaged 28.5 mm). After admitted, all patients were applied bone traction. After recuction, the fractures were fixed with percutaneous iliosacral 7.3 mm cannulated screws, which crossed the iliac and sacral-iliac joint and sacral promontory to S(1)vertebrae. After operation, all patients took X-ray examination. The reduction and the fracture reduction were judged according to Matta criterion and clinical function was judged according to Majeed functional scoring.ResultsForty-six patients were followed up from 1.5 to 3 years with an average of 29 months. Fracture uninon was achieved in all patients. All patients got clinical recovery at mean time of 5.2 months and returned to normal daily life. According to Matta criterion for fracture reduction, the results were excellent in 40 cases and good in 6 cases. According to Majeed functional scoring, 32 patients were excellent, 12 good and 2 normal. There were no serious complications of vascular damage.ConclusionPercutaneous iliosacral screw fixation is an effective technique with advantages of minimal invasive and faster recovery in the management of vertically unstable pelvic fractures.
