Biomechanics of Lower Limb Prostheses

Frequent lower limb amputations caused by the growing incidence of vascular diseases and traumatic injuries currently represent a significant global problem. A properly constructed and adjusted prosthetic device is a key to the reintegration of these patients into their family, social, and working environments.The main objective of the submitted article is to provide a clear summary of the principles regarding the lower limb prosthesis construction, highlight the fundamental principles and rules to be applied to the assembly in the assembly stand, and the static and dynamic assessment of a prosthesis. The article also briefly points out the necessity of proper construction of a prosthetic socket and in the concluding part it describes unfavourable consequences of the failure to adhere to the structural lines and improper adjustment of components during the gait.
