An upper-extremity amputation includes the removal of any part of an upper limb. The amputation level of an upper-extremity varies widely, and factors into what kind of prosthesis is most suitable for the amputee. Such levels include: partial finger/thumb amputation, metacarpal/transmetacarpal amputation, wrist disarticulation, transradial amputation, elbow disarticulation, transhumeral amputation, shoulder disarticulation, and forequarter amputation.
