The best level of amputation must take into consideration the newest socket designs, methods of prosthetic suspension, and technologically advanced components. In some instances stump revision should be considered, to provide a better prosthetic fitting and function. Targeted reinnervation is a new neural-machine interface that has been developed to help improve the function of electrically powered upper prosthetic limbs. Osseointegrated implants for prosthetic suspension offer amputees an alternative to the traditional socket suspension, and are especially useful for transfemoral and transhumeral levels of amputation. Cadaver bone can be used to lengthen an extremely short residual bony lever arm.

Introduction: Rhizarthrosis, or osteoarthritis of the trapeziometacarpal joint, predominantly affects women over 50, with up to 30% experiencing some degree of arthritis in this joint. Traditional surgical approaches, such as trapeziectomy with ligament reconstruction, can result in some patients in persistent pain or limited functionality. TMC ball-in-socket arthroplasty, with a cup placed in the distal scaphoid, offers a promising alternative to traditional arthrodesis or resection-suspension arthroplasty.

Improper socket fitting in lower-limb prostheses can lead to significant complications, including pain, skin lesions, and pressure ulcers. Current suspension and socket design practices rely predominantly on visual inspection of the residual limb and patient feedback. Monitoring stress distribution at the residual limb/socket interface offers a more objective approach.
