To compare patients with acetabular fractures that are isolated (acetabular fracture alone) and acetabular fracture presenting with additional non-acetabular injury using functional outcomes, complications, and readmissions.
Retrospective review SETTING:: Level 1 Trauma CenterPatients/Participants: 215 patients underwent open surgical treatment for acetabular fracture between 2003 and 2012 with age ≥18 years and minimum one year follow-up inclusive of functional scores and complications.
Surgical treatment of acetabular fracture.
Post-operative functional outcomes at one year as assessed with the Short Form 36 (SF36) health survey questionnaire and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), post-operative complications including readmissions.
Acetabular fractures patients with associated non-acetabular injuries exhibited a longer length of hospital stay (p<0.0001) and higher readmission rate within 90 days (p=0.012) compared to patients in the isolated injury group. Acetabular fracture with either chest or abdominal injury had the longest average hospital stay (19.2 & 19.1 days respectively). Functional scores between two groups were comparable at 1 year follow up, except acetabular fractures with pelvic ring injury, which had a significantly lower physical component score of SF-36 (p =0.007) compared to the isolated group.
Acetabular fractures with associated non-acetabular injuries have longer hospital stays, higher complications, and readmissions. Specifically, patients with associated truncal injury had worse clinical outcome and longer hospital stays. These conclusions should be taken into account when counseling patients with acetabular fractures, as additional injuries will greatly affect the course of treatment and the outcomes.
