# Medial femoral condyle free flap for reconstructions of medication related osteonecrosis of the jaw

## TL;DR

A 57-year-old woman with jaw osteonecrosis due to cancer treatment was successfully treated with a specific type of tissue flap.

## Contribution

The study presents a successful case of using a medial femoral condylar free flap for MRONJ reconstruction.

## Key findings

- The patient recovered without complications after MFC free flap surgery.
- Normal jaw function was maintained at two-year follow-up.
- MFC free flap is a viable option for small mandibular defects in MRONJ patients.

## Abstract

Medication-related osteonecrosis of the jaw (MRONJ) is a rare complication of antiresorptive therapy that may require free tissue reconstruction. A 57-year-old woman with metastatic breast cancer developed refractory mandibular MRONJ after intravenous zoledronic acid and underwent reconstruction with a medial femoral condylar (MFC) free flap. She recovered without complications and maintained normal function at two-year follow-up. This case supports the MFC free flap as a viable option for small, partial-thickness mandibular defects in selected patients with MRONJ.
