People with lower limb amputation have many problems with socket prosthesis includingdermatitis, infected sores, difficulty with socket fit, fatigue due to high energy consumption,impaired quality of life and other complications. The aim of the Endo-Exo Prosthesis is toprevent problems at the interface between the sleeve of the socket-prosthesis and the softtissue coat of the limb stump. In 2018, I implanted endo module prosthesis into the leftfemur of a 32years old male by a cobalt- chrome alloy device covered with spongiosa metal.It creates a deep porous surface and favorable modulus for bone formation. Closure of thesoft tissue over the stump just to give the spongiosa of the femoral bone enough time tointegrate. After six weeks, through the intermediate module, Exo-prothesis is attached. Theresult of Endo- Exo prosthesis represents a significant improvement such as the absence ofskin irritations, pressure-related injuries, improved mobility as a result of less restriction ofmovement, an improvement in sense of position and tactile sensation following care with the Endo-Exo prosthesis. This in turn leads to an improved gait pattern and life.
