positions to avoid in transtibial amputation for contracture prevention
prolonged flexion and ER at hip
knee flexion
how to avoid transtibial contractures such as knee flexion or hip flexion
use posterior board when in wheelchair to keep knee straight
regular scheduled time in prone
positions to avoid in transfemoral amputation for contracture prevention
flexion , abduction, ER of hip
how to counteract contracture formation
regular scheduled time in prone positions
avoid pillows under stump in supine positions
Circumduction gait deviation with transfemoral prosthetic causes
long prosthesis locked knee small or loose socket inadequate suspension foot plantar flexed abduction contracture poor knee control
abducted gait with transfemoral prosthesis causes
crotch or medial wall discomfort from too high medial wall or sharp medial wall
long prosthesis
low lateral wall or malalignment
tight hip abductors/abduction contracture
instability of hip joint
vaulting gait pattern with transfemoral prosthesis causes
prosthesis too long inadequate suspension socket too small prosthetic foot in too much plantarflexion too little knee flexion too fast gait speed
lateral trunk bending in stance with transfemoral prosthesis causes
low lateral wall short prosthesis high or sharp medial wall weak abductors abductor contractures hip pain short amputation limb
forward flexion during stance with transfemoral amputation causes
unstable knee unit
short ambulatory aids
hip flexion contracture
lumbar lordosis with transfemoral amputation causes
insufficient support from anterior or posterior walls painful ischial weight bearing hip flexion contracture weak hip extensors or abdominals inadequate socket flexion
high heel rise with transfemoral prosthesis causes
inadequate knee friction
too little tension in extension aid
terminal swing impact with transfemoral prosthesis causes
insufficient knee friction
too much tension in extension aid
patient fears knee will buckle
forecfull hip flexion
swing phase whip with transfemoral prosthesis causes
socket is rotated
knee bolt is rotated
foot is malaligned
socket donned malaligned
foot rotation at heel strike with transfemoral prosthesis causes
foot is malaligned
stiff heel cushion
plantar flexion bumper
foot slap with transfemoral prosthesis causes
heel cushion or plantar flexion bumper is too soft
uneven step length with transfemoral prosthesis causes
socket discomfort
poor alignment
hip flexion contracture
hip instability
excessive knee flexion in stance with transtibial prosthesis causes
socket aligned too far forward socket tilted too far anteriorly plantar flexion bumper too hard high heel shoes knee flexion contracture weak quadriceps insufficient plantar flexion stiff heel cushion
inadequate knee flexion in stance with transtibial prosthesis causes
socket may be aligned too far back or tilted posteriorly
plantar flexion bumper or heel cushion too soft
low heel shoes
anterodistal discomfort
weak quadriceps
arthritis
lateral thrust at midstance transtibial prosthesis causes
foot is inset too much
medial thrust at midstance transtibial prosthesis causes
foot is outset too much
drop off or premature knee flexion in late stance transtibial prosthesis causes
socket is set too far forward or excessively flexed
dorsiflexion bumper too soft resulting in excess DF
prosthetic foot keel too short
knee flexion contracture
delayed knee flexion during late stance transtibial prosthesis causes
socket set too far back or lacks sufficient flexion
dorsiflexion bumper too stiff causing excess PF
prosthetic foot keel too long
