# Case report and presentation of a new classification system for hip acetabular and periacetabular ossifications and calcifications

## TL;DR

A rare case of hip calcifications in a middle-aged woman is reported, along with a new classification system for acetabular and periacetabular calcifications.

## Contribution

A new classification system for acetabular and periacetabular ossifications and calcifications is proposed.

## Key findings

- Double calcifications of the acetabular labrum and rectus femoris occurred in a middle-aged female patient.
- Surgical intervention via hip arthroscopy successfully treated the patient.
- The case demonstrates the variety of calcifications around the acetabulum.

## Abstract

This report describes a rare case in which double calcifications of the acetabular labrum and rectus femoris occurred concomitantly in a middle-aged female patient who was treated successfully with surgical intervention via hip arthroscopy.

This case highlights the existence of various types of calcifications around the acetabulum, with a proposed new classification system for acetabular and periacetabular rim ossifications.
