title: Comparison of Outcomes and Complications of Isolated Acetabular Fractures and Acetabular Fractures With Associated Injuries.
abstract: OBJECTIVE
  To compare patients with acetabular fractures that are isolated (acetabular fracture alone) and acetabular fracture presenting with additional nonacetabular injury using functional outcomes, complications, and readmissions.
  
  
  METHODS
  Retrospective review.
  
  
  METHODS
  Level 1 Trauma Center.
  
  
  METHODS
  Two hundred fifteen patients underwent open surgical treatment for acetabular fracture between 2003 and 2012 with age ≥18 years and minimum 1-year follow-up inclusive of functional scores and complications.
  
  
  METHODS
  Surgical treatment of acetabular fracture.
  
  
  METHODS
  Postoperative functional outcomes at 1 year as assessed with the Short Form 36 (SF-36) Health Survey Questionnaire and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), postoperative complications including readmissions.
  
  
  RESULTS
  Acetabular fractures patients with associated nonacetabular injuries exhibited a longer length of hospital stay (P < 0.0001) and higher readmission rate within 90 days (P = 0.012) compared with patients in the isolated injury group. Acetabular fracture with either chest or abdominal injury had the longest average hospital stay (19.2 and 19.1 days, respectively). Functional scores between 2 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 with the isolated group.
  
  
  CONCLUSIONS
  Acetabular fractures with associated nonacetabular 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.
  
  
  METHODS
  Prognostic level III. See Instructions for Authors for a complete description of levels of evidence.
