Even though, the treatment of femoral bone loss has remained a difficult problem throughout medical history. The patient finds the circular fixator's lengthening technique of bone treatment to be uncomfortably uncomfortable. In other words, these fixators, have some drawbacks in terms of pain, discomfort in the patient and price, as they are not available for poor families. Therefore, the aim of this study was to optimise the existing circular medical device topography to satisfy the general demand. This study involved the use of analytical methods by studying the finite element analysis of the fixator using a software named Abaqus Das-sault System where a variety of models were developed using different types of materials like stainless steel, titanium, and carbon fibre. This study was assumed to be done by mimicking the real-world conditions using the finite element analysis software Abaqus. The result of the simulation study has shown that using the deflection of the bar is due to high load applied and that cos is related to the quantity and type pf materials used. Also, the topography Optimisation using tosca has shown a reduction in the device weight by 40%. Although this study has presented satisfactory results, there is still a need for further studies regarding the structure and type of materials used for the medical device.FulltextenBone fracturesExternal fixation devicesFracture treatmentCircular medical device topographyAbaqus Das-sault SystemBook ChapterN/A
