Hip Strength and Nerve Palsy After the Modified Stoppa Approach to Acetabular Fracture Reduction and Fixation
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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).
Outpatient physical therapy strength testing will be used to assess hip adductor strength in all participants (subjects and controls). [ Time Frame: 1 year follow-up after surgery ]
Secondary Outcome Measures :
Radiographs and clinical assessment at follow-up appointments will be used to determine incidence of obturator nerve palsy in both groups (subjects and controls). [ Time Frame: 1 year follow-up after surgery ]

Ages Eligible for Study:
18 Years to 99 Years (Adult, Senior)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Pelvic fracture patients and patients treated for acetabular fractures with the modified Stoppa approach will be asked to consent to a voluntary study investigating physical function at their 2 week follow-up appointment.
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.
Exclusion criteria for the subject and control patient population consist of:
Patients who are non-ambulatory.
Patients less than 18 years of age.
Patients who do not speak English.
Patients who are unable to complete their follow-up in Utah.
