Brief summary

The purpose of this prospective study is to compare hip adductor strength and obturator nerve palsy between acetabular fracture patients whose fracture was reduced and fixated using the modified Stoppa approach (subjects) and pelvic fracture patients (controls) using physical strength testing, radiographs, clinical assessment, and a validated functional outcome questionnaire. The investigators' research hypothesis is that there will be less strength and higher incidence of obturator nerve palsy in patients treated with the modified Stoppa approach (intervention) than in patients treated without the modified Stoppa approach (controls).

Inclusion criteria

* Inclusion criteria for the subject patient population under study consists of male and female adults, at least 18 years old, who had an acetabular fracture that was treated with the modified Stoppa approach. * Inclusion criteria for the control patient population under study consists of male and female adults, at least 18 years old, who had acetabular fractures with similar fracture patterns as the study group that were treated with any other approach than the Stoppa approach.

Design outcomes

Primary

Measure	Time frame
Outpatient physical therapy strength testing will be used to assess hip adductor strength in all participants (subjects and controls).	1 year follow-up after surgery

Secondary

Measure	Time frame
Radiographs and clinical assessment at follow-up appointments will be used to determine incidence of obturator nerve palsy in both groups (subjects and controls).	1 year follow-up after surgery
