Management of anterior associated types of acetabular fractures utilizing the modified Stoppa and the pararectus approaches: a prospective cohort study and early experience from a level one Egyptian trauma centre.

Abstract

This study aimed to report the early experience (radiographic, functional, and complications outcomes) from an Egyptian (North African) level one trauma centre after utilizing the modified Stoppa and the pararectus approaches to manage anterior-associated types of acetabular fractures. Between January 2014 and April 2018, 63 patients (40 males and 23 females) with a mean age of 33 ± 11.5 were included, 45 patients were treated through the modified Stoppa (group A), and 18 through the pararectus approach (group B). At a mean follow-up of 32.11 ± 15.36months (range 12 to 64), 56 patients (43 group A and 13 group B) were evaluated. The post-operative anatomical reduction was achieved in 44 (78.6%) patients. At the last follow-up, Matta radiological outcome grades were excellent and good in 50 (89.2%) patients, fair and poor in six (10.8%). The mean Harris Hip Score (HHS) was 92.6 ± 7.6; the mean modified Merle D'Aubigné (MMD) score was 16.5 ± 1.5. Excellent functional outcome was reported in 42 (75.0%) and 25 (44.6%) patients according to HHS and MMD scores, respectively. There are four (7.1%) intra-operative iatrogenic complications (two in each approach), three (5.3%) vascular injuries (two in group B and one in group A), and one (1.8%) bladder injury in group A. Employing less-invasive anterior approaches for managing anterior associated types of acetabular fractures proved efficiency and safety. Good to excellent radiological and functional outcomes were achieved, with no significant difference between both approaches.
