Indirect Reduction of Posterior Column through Ilioinguinal Approach in Case of Both Column Fractures

ABSTRACT

PURPOSE: To evaluate the efficacy and results of indirect reduction of the posterior column through the ilioinguinal approach in cases of both column fractures. MATERIALS AND METHODS: Between February 2000 and January 2008, 18 patients, who underwent indirect reduction of the posterior column through the ilioinguinal approach, were evaluated clinically and radiographically after a minimum follow-up of one year. The mean follow-up duration was 52.7 months. The reduction quality, clinical results, and radiographic results were analyzed according to the criteria reported by Matta. The complications were also recorded. RESULTS: There were 13 cases (72.2%) of an anatomical reduction, 2 cases (11.1%) of an imperfect reduction, and 3 cases (16.7%) of a poor reduction. Out of 13 anatomically reduced fractures, excellent results were graded in 12 cases clinically and 9 cases radiographically. Poor clinical and radiographic results were graded in 2 of the 3 poorly reduced fractures. Complications included 3 cases with transient lateral femoral cutaneous nerve injury, which resolved during the follow-up period and 1 case with an injury to the superior gluteal artery. CONCLUSION: Indirect reduction of the posterior column through the ilioinguinal approach is effective for both column fractures. During surgery, care should be taken to reduce the risk of iatrogenic lateral femoral cutaneous nerve injury.
