Basic socket design for high level LE amputee
flexible thermoplastic or silicone within rigid frame is the most comfortable option
Most important aspect of socket design for high level amputees
- careful fitting
- secure suspension
alignment stability for high-level LE amputee
- same as normal limb
- in midstance, GRF should fall posterior to the hip and anterior to the knee
dysvascular pts: How does loss of one limb affect the risk of eventual bilateral limb loss?
up to 50% more likely to lose contralateral limb within 5 years
How does energy consumption change for the B LE amputee?
- increased
- especially if they don’t have a biological knee
Longer residual limb and energy cost
lower energy cost to walk with prosthesis
How does rehab change for the B LE pt?
- similar to single limb amputation
- occurs in phases
phases of rehab for B LE amputee
- preoperative (time permitting)
- immediate postoperative
- acute rehab
How does gait change for the B LE pt?
- 2 artificial limbs are more difficult
- walk slowly and cautiously
What does gait look like for a B LE pt?
- wide BOS to maximize stability
- shorter step length
- slower speed/cadence
- hip hiking in swing
What are stubbies?
shortened pair of prostheses used for early gait training
Who are stubbies used with?
B traumatic TF amputation
What are the advantages of using stubbies?
- can develop postural control without having to worry about stability of prosthetic knee units
- require less energy and balance
gives the best chance for successful amputation
