# Surgical Management and Reconstruction of Dedifferentiated Chondrosarcoma in the Proximal Femur: A Case Report

## TL;DR

This case report discusses the surgical treatment and reconstruction for a rare bone cancer in the upper thigh bone.

## Contribution

The paper presents a detailed case report on the surgical management of dedifferentiated chondrosarcoma in the proximal femur.

## Key findings

- Surgical treatment involves two stages: tumor resection and reconstruction.
- Wide excision with adequate soft tissue margins is crucial for curative purposes.
- Reconstruction methods include composite or massive prostheses for mechanical stability.

## Abstract

A primary malignant bone tumor, or more commonly, metastasis, can occur in the proximal femur. Surgical treatment can have palliative or curative purposes. In the case of the latter, it involves two stages: resection of the tumor, which aims to address the cancer, and reconstruction of the bone and soft tissue, which aims to restore function. It is important for the excision to be wide with adequate resection margins in the soft tissue, particularly when the goal is curative treatment. Typically, surgery involves excision and reconstruction to ensure good mechanical stability. Reconstruction can be done using different methods, such as a composite prosthesis or a massive prosthesis, which may be modular or custom-made. Joint reconstruction options include hemiarthroplasty, intermediate prosthesis, or, in some cases, total hip replacement.
