Reconstruction and Performance Mega Prosthesis Distal Femur: A Review

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A modular mega prosthesis is the most common method of reconstruction after resection of segmented long bones. The advantage of using modular prostheses is for its known better result in distal femur tumors. The Mega Prosthesis is a prosthesis inside of the thigh. This study aims to investigate the mechanical and non-mechanical failure rates of six modular mega prosthesis types of distal femur implants. The reason for selecting this subject is that in the next study, we aim to develop a set of distal femoral modular mega prostheses that are dependable in the face of failure that may occur when it is attached to the body. To achieve that goal, we conducted research that focused on assessing the performance of various distal femoral mega prosthesis modular implants by examining implant data affected by five types of failure mechanisms. To reconstruct it there are three stages, including distal femur resection and soft tissue replacement. Causes of failures can be classified according to Henderson et al. in five types: Type 1 (soft tissue failure), Type 2 (aseptic loosening), Type 3 (structural failure) Type 4 (infection), and Type 5 (tumor progression). The average monthly usage of implants from GMRS Distal Femur (Stryker Orthopaedics) is the most prevalent, with an average of 7 implants per month. Each of the six types of distal femur implants' performances have its own set of benefits and drawbacks. In terms of overall performance, KR-HDFP (Howmedica, Inc) has the lowest figure of merit of 0.224.
