Successful Arthroscopic Fixation of a Posterior Wall Acetabular Fracture Nonunion on a Patient With Femoroacetabular Impingement: A Case Report.

CASE: This report presents the results of a hip arthroscopic technique that was used to treat an unusual posterior wall acetabular fracture nonunion. A 30-year-old man presented with 1 year of persistent left-sided buttock and groin pain with associated feeling of instability when climbing stairs. Magnetic resonance imaging demonstrated a small left acetabular posterior wall fracture nonunion. We describe outpatient treatment with reduction and cannulated screw fixation using arthroscopic techniques that permitted immediate partial weight bearing and achieved excellent outcomes at 1 year.

CONCLUSION: Arthroscopic fixation of an acetabular posterior wall fracture nonunion may be a feasible treatment option in select cases.
