Background
Acetabular fractures in the elderly and severely comorbid patient can be associated with high morbidity and mortality; however, differences in outcomes of acute ORIF versus non-operative care of acetabular fractures in a subgroup of elderly (>75 years) and/or severely comorbid younger patients (>65) remain unclear.
Patients and methods
A retrospective review of 243 patients who sustained an acetabular fracture between April 2005 and November 2014 was performed. Eighty-seven patients met inclusion criteria: age > 75 with or without comorbidities or age > 65 if complicated by two or more medical comorbidities. Outcomes measures evaluated were 1-year mortality, duration of hospital stay, return to pre-injury ambulation status and treatment failure marked by conversion to a total hip arthroplasty (THA) within 1 year of treatment.
Results
Thirty-seven patients with acetabular fractures were treated with surgical fixation, and 49 were treated non-operatively. Operative patients did not demonstrate a statistically significant difference in mortality within 1 year of treatment compared to non-operatively treated patients. Operative patients demonstrated a statistically significant increase in treatment failure marked by a conversion to a THA within 1 year when compared to conservatively treated patients. No differences in age, duration of follow-up, or ability to return to baseline at latest clinical follow-up were found between groups. However, non-operatively treated patients had a higher incidence of Alzheimer’s disease/Dementia and Parkinson’s compared to operatively treated patients.
Conclusion
Analysis of our small cohort suggests that there may be a role for the non-operative treatment of acetabular fractures in this debilitated patient population despite a somewhat longer length of hospital stay at the time of injury. Conversion to THA was significantly higher at 1 year in our operated patients. No differences in mortality at 1 year were noted between patient groups. Return to baseline ambulation status was slightly higher in the non-operated group but not significantly so. However, a potential bias to more likely treat complex fractures operatively cannot be ruled out, as non-operative fractures were most often anterior column variants, usually more amenable to non-operative care.
