Interscapular–Thoracic Amputation and Shoulder Disarticulation
Forearm Lift Assist
The forearm lift assist can be added to any mechanical elbow to reduce the force necessary to flex the elbow.
An interscapular-thoracic amputation is the surgical separation of the humerus (upper arm bone), scapula (shoulder blade), and a portion of the clavicle (collar bone) from the body. In this procedure the entire shoulder and arm are removed.
Nudge Control Unit
The nudge control unit is a paddle-shaped device that is used by upper extremity amputees. It is often activated by the patient’s chin. It is typically prescribed when other body movements are not available. The nudge control can be used to provide small amounts of cable excursion, to lock and unlock a prosthetic elbow, or to control a wrist unit.
A shoulder disarticulation procedure is the surgical separation of the entire arm from the shoulder joint. In this surgery the humerus (upper arm bone) and the entire arm are removed from the scapula (shoulder blade) and clavicle (collar bone). No bones are cut during this surgery.
Shoulder Disarticulation Prosthesis
The shoulder disarticulation prosthesis can be a passive restoration, or it may be myoelectrically controlled. This prosthesis incorporates an artificial shoulder, elbow, wrist and hand.
Shoulder joints come in varying degrees of motion. The simplest does not allow any motion. The single axis shoulder joint only allows abduction (moving the arm out to the side). The double axis joint allows abduction (moving the arm out to the side) and flexion and extension (moving the arm forward and backward). The most complex shoulder joint is a ball-and-socket design that allows motion in all directions.
Soft Tissue Supplement
Soft tissue supplements are fabricated for patients who are concerned about cosmesis (looks) or to improve function. They may be constructed of foam, leather, or silicone materials to replace tissues lost through trauma or disease.
