# Pelvic Osteochondroma Causing a Painful Anterior Snapping Hip With Concomitant Femoroacetabular Impingement: A Case Report

## TL;DR

A rare case of hip pain caused by a pelvic osteochondroma combined with femoroacetabular impingement was successfully treated with surgery.

## Contribution

This case report highlights the rare coexistence of osteochondroma and femoroacetabular impingement as a cause of hip pain.

## Key findings

- Pelvic osteochondroma can cause painful anterior snapping hip and mimic femoroacetabular impingement symptoms.
- Combined arthroscopic and open surgical approaches resolved both FAI and osteochondroma-related hip pain.
- Early advanced imaging is crucial to identify all hip pathologies in young patients.

## Abstract

The differential diagnosis for hip pain in a young patient can present a diagnostic challenge. We present an unusual case of concomitant femoroacetabular impingement (FAI) and painful internal snapping hip caused by an osteochondroma of the superior pubic ramus. The patient was treated with arthroscopic labral repair and femoral osteochondroplasty, and open osteochondroma excision, resulting in complete resolution of both FAI and snapping hip. Pelvic osteochondroma is an uncommon cause of hip pain that can mimic FAI symptoms. Early advanced imaging and combined approaches may be necessary to ensure that all causes of hip pathology are addressed.
