ANSWERS | GRADED A+
Rigid dressings (advantages and disadvantages) Early WB, limits edema and postop pain,
enhances wound healing, earlier fit of permanent prosthetic; does not allow for daily wound
inspection (CI with CV compromise and increased wound risk), requires skilled application
Causes of Circumduction (Transfermoral selected prosthetic gait deviations) long prosthesis,
locked knee, small or loose socket, inadequate suspension, foot plantar flexed, abduction
contracture, poor knee control
Causes of Abducted gait (Transfermoral selected prosthetic gait deviations) medial wall
discomfort, long prosthesis, low lateral wall or malalignment, tight hip abductors
Causes of vaulting (Transfermoral selected prosthetic gait deviations) prosthesis too long,
inadequate suspension, socket too small, prosthetic foot set in too much PF, too little knee
flexion
Causes of lateral trunk bending (Transfermoral selected prosthetic gait deviations) low
lateral wall, weak abductors, high medial wall, short prosthesis, abductor contracture, hip pain,
short residual limb
Causes of forward flexion (Transfermoral selected prosthetic gait deviations) trunk bends
forward, unstable knee unit, short ambulatory aids, hip flexion contracture
, Causes of lumbar lordosis in stance (Transfermoral selected prosthetic gait deviations) hip
flexion contracture, weak abdominals, weak hip extensors, insufficient anterior or posterior
wall support, painful ischial WB
Causes of High heel raise (Transfermoral selected prosthetic gait deviations) during early
swing the heel rises excessively; inadequate knee friction, too little tension in the extension aid
Causes of Terminal swing impact (Transfermoral selected prosthetic gait deviations)
insufficient knee friction or too much tension in the extension aid; pt fears knee will buckle;
forceful hip flexion
Causes of swing phase whips (Transfermoral selected prosthetic gait deviations) at toe off
the heel moves lateral or medial; socket is rotated, knee bolt is rotated, foot malaligned
Causes of foot rotation at heel strike (Transfermoral selected prosthetic gait deviations) foot
is malaligned, stiff heel cushion, stiff PF bumper
Causes of foot slap (Transfermoral selected prosthetic gait deviations) soft heel cushion or
soft PF bumper
Causes of uneven step length (Transfermoral selected prosthetic gait deviations) socket
discomfort, hip flexion contracture or hip instability, poor alignment
