Study Notes

Amputation Types

Forequarter (Scapulothoracic): Removal of upper extremity including shoulder girdle.
Shoulder Disarticulation: Removal of the upper extremity through the shoulder.
Transhumeral: Removal of upper extremity proximal to elbow joint.
Elbow Disarticulation: Removal of lower arm and hand through the elbow joint.
Ray Section Amputation: Removal of a toe and part of corresponding metatarsals; first ray removal is particularly challenging.
Transradial: Removal of upper extremity distal to elbow joint.
Wrist Disarticulation: Removal of the hand through the wrist joint.
Digital Amputation: Removal of a digit at metacarpophalangeal, proximal interphalangeal, or distal interphalangeal level.
Hemicorporectomy: Removal of pelvis and both lower extremities.
Hemipelvectomy: Removal of one half of the pelvis and lower extremity.
Hip Disarticulation: Removal of lower extremity from the pelvis.
Transfemoral: Removal of lower extremity above the knee joint.
Knee Disarticulation: Removal of lower extremity through the knee joint.
Transtibial: Removal of lower extremity below the knee joint.
Syme's Amputation: Removal of the foot at the ankle joint, including malleoli.
Transverse Tarsal (Chopart's): Amputation through talonavicular and calcaneocuboid joints; preserves plantarflexors, sacrifices dorsiflexors, often causing equinus contractures.
Tarsometatarsal (Lisfranc): Surgical removal of metatarsals; preserves dorsiflexors and plantarflexors.
Long Transtibial: Removal of distal third of tibia below the knee.
Short Transtibial: Removal of limb at proximal third of tibia.

Prosthetic Components

Transradial Socket: Covers two-thirds of forearm; may be shortened for increased pronation/supination.
Transradial Suspension: Includes a triceps cuff, harness, and cable system.
Transradial Elbow Unit: Attaches to triceps cuff or upper arm pad; connected with flexible or rigid hinge.
Transradial Wrist Unit: Quick change unit; includes wrist flexion unit, ball and socket, and constant friction.
Transradial Terminal Device: Includes voluntary opening/closing; can be body-powered, externally powered, myoelectric, or hybrid; options include hook, mechanical hand, cosmetic glove.
Transhumeral Socket: Standard design extends to acromion level; modified for greater rotational stability; lightweight friction units available for passive prosthetic arms.
Transhumeral Suspension: Utilizes harness, cable system, and suction.
Transhumeral Elbow Unit: Comes in internal or external locking mechanisms.
Transhumeral Wrist Unit: Quick change unit with wrist flexion unit, ball and socket, and constant friction.
Transhumeral Terminal Device: Features voluntary opening/closing; options include body-powered, externally powered, myoelectric, or hybrid.
Transfemoral Socket: Includes quadrilateral socket and ischial containment socket.
Transfemoral Suspension: Includes laynard strap, shuttle lock, suction (seal in liner), partial suction, and vacuum systems.
Transfemoral Knee: Varieties include single axis, polycentric, hydraulic, and microprocessor knee.
Transfemoral Shank: Comes in exoskeleton (rigid exterior) and endoskeleton (pylon with foam cover).
Transfemoral Foot System: Features solid ankle cushion heel.
