the leading causes of upper extremity amputations (4)
- trauma
- congenial deficiency
- tumor
- disease
amputation levels: transradial amputation
below the elbow: long, medium, short
amputation levels: transhumeral amputation
above the elbow: 50-90% of humeral length
A successful prosthesis is:
- comfortable
- easy to don/doff
- lightweight
- durable
- cosmetically pleasing
- functions well
- reasonable maintenance
- motivates individual
the components of an upper limb prosthesis
- suspension
- socket design
- alignment
- terminal devices: hooks, hands
