Abstract

Background:

A custom endoprosthesis allowed for the preservation of the distal femoral physis with a short remaining metaphyseal segment after osteosarcoma resection in a 10-year-old boy. CASE

Case Presentation:

This case illustrates a reconstructive alternative allowing physeal sparing with minimal remaining metaphyseal bone. At the three-year follow-up, the patient has remained complication-free with distal femoral growth maintaining symmetric limb length.

Conclusion:

When intercalary biologic reconstruction is not an option and the sacrifice of physis necessitates an extendible total femoral prosthesis, custom physeal sparing short segment press-fit fixation is an appropriate solution.
