Primary etiology of amputations
peripheral vascular disease
Hemicorporectomy
surgical removal of the pelvis and both lower extremities
Hemipelvectomy
surgical removal of one half of the pelvis and the lower extremity
Symes
surgical removal of the foot at the ankle joint with removal of the malleoli
Transverse tarsal
amputation through the talonavicular and calcaneocuboid joints. preservation of the plantarflexors, but severs the dorsiflexors (results in a equinus contracture)
Tarsometatasal
surgical removal of the metatarsals. preservation of the dorsiflexors and plantarflexors
Transradial - socket
Standard: covers 2/3 of forearm, can be shortened for increased pronation/supination
Supracondylar: self-suspending and require no additional harness
Transhumeral - socket
Standard: extends to acromion level
Modified design: allows for more stability with rotational movements
Lightweight friction: used with passive prosthetic arms
Transradial - suspension
Transhumeral - suspension
Transradial - elbow unit
attaches to triceps cuff or upper arm pad, flexible or rigid hinge connects socket to proximal component
Transhumeral - elbow unit
internal or external locking unit
Transradial/Transhumeral - wrist unit
Transradial/Transhumeral - wrist unit
Transfemoral - socket
Transtibial - socket
Transfemoral - suspension
Transtibial - suspenstion
Transfemoral - knee
Transfemoral/transtibial - shank
Transfemoral/transtibial - foot system
Rigid dressing
(+) early ambulation, stimulates proprioception, provides soft tissue support, ability to use immediate post-operative prosthesis
(-) cannot immediately inspect wound, cant do daily dressing changes, professional application
Semi-rigid dressing
(+) easily changeable, protection, soft tissue support
(-) does not protect as well as rigid, requires more changing, may loosen (develop edema)
Non-weight bearing rigid removable dressing
(+) removable, easily applied, prevents contracture, provides protection
(-) not for ambulatory purposes
