AbstractWe reviewed 77 patients with an acetabular fracture, treated operatively through a non-extensile approach after an average time of 45 months. The ilioinguinal approach was chosen in 41, the Kocher-Langenbeck approach in 36 patients. Following the Letournel classification, the most frequent lesions were posterior wall (26%), two-column (22.1%) and anterior column (14.3%) fractures. Subchondral impaction, intra-articular fracture fragments and fracture comminution, called modifiers, could be identified in the preoperative CT-data of 38 patients (49.4%). Patients were operated after an average of 4 days. Average hospital stay was 19 days. Sciatic nerve and peroneal nerve palsy were registered in 5.6%. Deep venous thrombosis was seen in 10.4%, peri-articular ossifications in 7.8%. During the 45-months follow-up, 10.4% patients needed secondary total hip arthroplasty. Using the Merle d'Aubigné score, 15 patients had an excellent, 39 a good, 15 a moderate, and 8 a bad result. In accordance with the Harris Hip Score, 29 patients achieved an excellent, 26 a good, 9 a moderate and 13 a bad result. Twenty of twenty-three (Merle d'Aubigné score) and twenty of twenty-two (Harris Hop Score) patients with moderate or bad results had one or more modifiers. Patients with operatively treated acetabular fractures, who had CT-findings such as subchondral impaction, fracture comminution or intra-articular fracture fragments in their preoperative examination, score significantly lower at middle term in the Harris Hip and Merle d'Aubigné scoring systems.Copyright © 2011 Elsevier Ltd.
