Pararectus Approach in Acetabular Fractures in Patients Older Than 65 years. Is it Possible to Improve the Technique?

Abstract

Review clinical results of the treatment for acetabular fractures using the pararectus approach and analyze surgical variations of the traditional approach. Retrospective. Tertiary referral hospital. 46 patients over 65 years of age who sustained an acetabular fracture and underwent surgery using the pararectus approach. Fractures were treated using a pararectus approach. Three variations of the original technique were performed: (1) Ligature of the deep iliac circumflex artery and vein, (2) separation of the psoas and iliacus muscles, and (3) isolation of the spermatic cord in men and round ligament in women together with the iliac and epigastric vessels. Outcomes measures included surgical, demographic, and clinical data, and information related to follow-up. Duration of surgery, 125 minutes (95-210). Quality of reduction on postoperative computed tomography (CT) scan; anatomic in 22 patients (47.8%), incomplete in 16 (34.8%), and poor in 8 (17.4%). In patients in whom the hip was preserved (n = 41), functional status was excellent in 15 patients (36.5%), good in 17 (41.4%), fair in 6 (14.7%), and poor in 3 (7.4%), with mean functional score of 16 points (7-18). Seven patients (15.2%) developed posttraumatic osteoarthritis and 4 of these patients underwent total hip replacement. This study reports positive outcomes in fracture reduction and clinical outcomes with low complications in older patients who suffered acetabular fractures and were treated using a pararectus approach. Small variations in the technique, such as those proposed in this study, may help to widen access to the surgical site and simplify the technique. Therapeutic Level IV.
