Abstract

Minimally invasive surgery (MIS) is fast becoming a preferred choice for patients and surgeons, due to its biological, aesthetic and commercial benefits. The dynamic hip screw (DHS) is the standard implant for the treatment of fractures of the proximal femur, which is considered to be the most frequent injury in the elderly. The aim of this research was to develop MIS for the treatment of these fractures utilising the principle and surgical technique of the DHS implant. During the research, a thorough medical device design process was conducted to develop three new medical devices 13 a new angle guide, a new ergonomic T-handle and a new implant. The design process for each of the new medical devices conformed to requirements of the relevant standards. The designs of the new medical devices were verified using methods such as risk analysis, finite element analysis and mechanical testing of manufactured prototype. Finally, an operative technique applying a minimally invasive approach with the new medical devices was developed to treat the fractures of the proximal femur.
