Purpose: The age of patients presenting with acetabular fracture has increased over the last ten years. Older patients tend to have patterns involving the anterior column with comminution of the quadrilateral plate. Our goal was to investigate the appropriateness of open reduction and internal fixation using the modified Stoppa approach for geriatric acetabular fractures.

Method: A retrospective review of patients over the age of 60 having presented to an academic level I trauma center over the course of four years. Twenty patients were identified and treated using the modified Stoppa approach with plating of the quadrilateral surface. Patients were evaluated clinically using both SF-36 and Harris Hip Score. Records and radiographs (using criteria described by Matta) were reviewed retrospectively.

Results: All patients were followed for a minimum of two years with no lost at follow-up. Mean age for patients at time of intervention was 68 years. Average blood lost was 800cc and surgical time was 130 minutes (range, 55–210). There was one traumatic injury to the obturator nerve and two patients were noted to have temporary weakness of the hip adductors postoperatively. Average Harris Hip Score and the SF-36 were improved significantly (p< 0.05). Significant lost of reduction was seen in two patients and was correlated to superior dome impaction (p < 0.0001). Three patients required re-intervention with a Total Hip Arthroplasty.

Conclusion: Internal fixation using the modified Stoppa approach to buttress the quadrilateral plate should be considered a viable alternative to total hip arthroplasty for the initial treatment of acetabular fractures of the anterior column in the elderly.
