Lower limb prostheses include a prosthetic socket that serves as the mechanical interface providing load transfer from the distal prosthesis to the residual limb. The remaining components include a prosthetic foot, a knee joint (if trans-femoral or more proximal level of amputation), and a hip joint (if hip disarticulation or more proximal amputation). The length of the shank or leg and thigh is established by internal pylons and various connective hardware (Figure 21.4).

After virtual disarticulation of the glenohumeral joint, a coordinate system was embedded on the glenoid cavity, built on three landmarks: i (superior), j (inferior) and k (anterior) at the edges of the glenoid (figure 2): with a superiorly directed unity vector IG, an anteriorly directed unity vector JG and a laterally directed unity vector KG, and centred in the position vector (i + j)/2 (figure 2).

The upper limb amputations are of different types: (a) Below elbow amputation (trans-radial): the partial removal of the forearm below the elbow joint; (b) wrist disarticulation: the removal of the hand and the wrist joint; (c) elbow disarticulation: the amputation of the forearm at the elbow; (d) above elbow amputation (trans-humeral): the amputation of the arm above the elbow; (e) metacarpal Amputation: the removal of the entire hand with the wrist still intact; (f) shoulder disarticulation and forequarter amputation – the removal of the entire arm, including the shoulder blade and collarbone.
