Hip Arthroscopy for Removal of an Acetabular Rim–Based Osteoid Osteoma and Concomitant Femoroacetabular Impingement Correction

Abstract

Minimally invasive percutaneous radiofrequency ablation (RFA) techniques are the standard of care for treating simple osteoid osteomas (OOs). Historically, OOs were treated with open en bloc resection or curettage of the nidus. RFA procedures have been linked to soft-tissue complications of varying severity. In addition, RFA may be a poor choice for periarticular OOs because of the potential for procedure-related articular cartilage damage. Hip arthroscopy is a widely accepted approach for the treatment of femoroacetabular impingement. We describe arthroscopic resection of an acetabular rim–based OO as part of a rim resection and labral repair. Early clinical follow-up suggests that arthroscopic resection of an OO in this unusual location is precise and predictable, allows for an additional evaluation of associated symptomatic pathology (i.e., femoroacetabular impingement), and results in prompt symptom resolution.
