Devices and Equipment Flashcards
Too short seat depth =
fails to support the thigh adequaltey
Too long seat depth =
- kyphotic posture
- PPT/sacral sitting
- compromises knee circulation
Excess leg length/seat footplate length =
encourages sacral sitting and sliding forward
Too short leg length/seat footplate length =
creates uneven weight distribution on thigh and excessive weight in ischial seat
-ischiall pressure sores
Amputation where there is a cut between the tarsals and metatarsals (tarsals spared)
LisFranc
Amputation at the distal tibia with preservation of the calcaneal fat pad
Syme’s
Amputation where the tarsal bones are cut but the talus and calcaneus (and malleoli) are spared
