Assessment of radiological and functional outcomes of complex acetabulum fracture managed with combined anterior and posterior approach in a single anaesthetic setting: a retrospective study.

Abstract

Background: Appropriate selection of surgical approach for associated fractures of the acetabulum that involves both columns is still elusive. Therefore, present study aimed to assess the quality of life of complex acetabulum fracture managed with combined anterior and posterior approach (dual approach) as well as the association of postoperative reduction and patient reported outcomes.

Material and methods: This retrospective study was performed on 42 associated acetabular fracture patients with involvement of both columns, who were treated with a dual approach including combined anterior modified ilio-inguinal approach in combination with posterior Kocher-Langenbeck (K-L) approach in a single anaesthetic session having minimum two years follow-up. Postoperative reduction and radiological outcomes were assessed using Matta criteria. Functional outcome was assessed by a score system developed by Merle d'Aubigné-Postel. Patient-reported outcomes were assessed using the 36-Item Short Form Survey (SF-36).

Results: The mean age of participants was 47.9 ± 11.95 years and mean follow-up period was 2.8 ± 0.49 years. Anatomical reduction was achieved in 32 (76.19%) cases in postoperative period. 8 (19.04%) cases had congruent and 2 (4.76%) had incongruent reduction. Radiological and functional outcome was excellent/good n = 35 (83.33%) cases. Patient-reported outcome on domains physical function and role physical showed a significant improvement between 6 to 24 months period (p < 0.001).

Conclusions: The dual approach for complex acetabulum fracture with mid-term follow-up showed good to excellent radiological and functional outcomes. A significant improvement in patient-reported outcomes on Physical function and Role physical domains of SF-36 was also seen over the follow-up period.
