Modified Stoppa Approach in Acetabular Fractures
Abstract
Purpose
The purpose of this study is to evaluate the clinical results of modified Stoppa approach in acetabular fractures.
Materials and Methods
Twelve patients who underwent surgery using the modified Stoppa approach for acetabular fractures were enrolled. There were 10 cases of isolated acetabular fracture, two cases of acetabular fracture combined with pelvic ring injury. There were two cases of anterior column fracture, nine cases of both column fracture, and one case of T-type fracture according to Letournel classification. The clinical outcomes were evaluated from Harris hip score (HHS) at postoperative one year and complications. The radiologic result was evaluated according to Matta criteria; anatomical, imperfect, and poor.
Results
According to the radiological results, there were eight cases of anatomical, three cases of imperfect, and one case of poor reduction. The average HHS was 82.5 and 10 patients had excellent or good results. The other two patients had poor results due to lumbosacral plexopathy and poor reduction, respectively. The complication included one case of incomplete sciatic nerve palsy, which was recovered at postoperative three months.
Conclusion
Internal fixation of acetabular fractures using the modified Stoppa approach had satisfactory clinical and radiological outcomes. The modified Stoppa approach can be a useful option for acetabular fractures with appropriate indication and anatomical information.
