Abstract
IntroductionAim of this retrospective analysis of prospectively collected data was to evaluate the functional mid-term outcome two years after open reduction and internal fixation of acetabular fractures involving the anterior column with affection of the quadrilateral plate using the pararectus approach on a large cohort.MethodFifty-two patients (12 female, 40 male) with a median age of 55 (range 18–90) years and displaced acetabular fractures involving the anterior column were surgically treated in a single level I trauma centre between July 2012 and February 2016 using the pararectus approach. Thirty-four patients (8 female and 26 male) with a median age of 58 (range 20–85) years were available for complete clinical follow-up at regular intervals, finally 24 months post-operatively. Functional outcome was evaluated according to modified Merle d’Aubigné score, Lower Extremity Functional Scale, WOMAC, and SF-36.ResultsRange of time between trauma and surgical treatment was three (range 0–19) days. Operation time was 140 (range 60–240) minutes, and duration of hospital treatment was 19 (range 7–38) days. Functional results in 34 patients available for final follow-up demonstrated 68 points (median; range 39–80) according to the Lower Extremity Functional Scale, 6% according to the WOMAC (mean; SD ± 14.5%), and 69% (mean; SD ± 20.1%) according to the SF-36. The modified Merle d’Aubigné score was excellent in 22 patients, good in eight patients, and fair in four patients.Discussion/conclusionBased on the good to excellent functional mid-term follow-up results of this study, the pararectus approach can be recommended as sufficient alternative single access to address displaced acetabular fractures involving the anterior column, independent of patients’ age.
Highlights
Aim of this retrospective analysis of prospectively collected data was to evaluate the functional mid-term outcome two years after open reduction and internal fixation of acetabular fractures involving the anterior column with affection of the quadrilateral plate using the pararectus approach on a large cohort
The gold standard approach for open reduction and internal fixation of acetabular fractures involving the anterior column was the ilioinguinal approach introduced by Letournel [1]
While the ilioinguinal approach exposes the pelvic brim under direct visualization except for the quadrilateral plate and the acetabular dome, which may result in a suboptimal reduction of impacted acetabular dome fractures or displaced quadrilateral plate, the modified Stoppa approach allows direct view under the pelvic brim including the quadrilateral plate [8]
Summary
Aim of this retrospective analysis of prospectively collected data was to evaluate the functional mid-term outcome two years after open reduction and internal fixation of acetabular fractures involving the anterior column with affection of the quadrilateral plate using the pararectus approach on a large cohort. Method Fifty-two patients (12 female, 40 male) with a median age of 55 (range 18–90) years and displaced acetabular fractures involving the anterior column were surgically treated in a single level I trauma centre between July 2012 and February 2016 using the pararectus approach. Discussion/conclusion Based on the good to excellent functional mid-term follow-up results of this study, the pararectus approach can be recommended as sufficient alternative single access to address displaced acetabular fractures involving the anterior column, independent of patients’ age. Only few studies on functional outcome exist in the literature, and cohort groups are comparatively small resulting in a strong need for further clinical data [10, 11]
