Amputations Flashcards
What is the most common cause of scapulothoracic amputation?
Malignancy; uncommon to see functional prosthetic used, lightweight one designed for cosmetic purposes
What is the most common cause of shoulder disarticulation?
Malignancy or severe electric injuries; functional prosthetic is possible
What is most common cause of transhumeral amputation?
Trauma; 7-10 cm proximal to distal humeral condyles, 2nd most common UE amputation
What is most common cause of elbow disarticulation?
Trauma; allows for self suspending socket
What is most common cause of transradial amputation?
Trauma; functionally preferred over wrist disarticulation, min 5 cm proximal to distal radius, most common UE amputation
Wrist disarticulation
Uncommon level of amputation, cosmetic and functional prosthetic disadvantages
Partial hand amputation
Limb sparing technique used to preserve functional pinch
Toe transfer to replace thumb may be option of prosthetic fails
Digit amputation
Prosthetics not often used, long transracial amputation may be more functional if multiple digits involved
What is most common cause of hemipelvectomy and hip disarticulation?
Malignancy; not able to activate prosthetic through residual limb, prosthetic motion must be initiated through weight bearing
Which motions are susceptible to contractures in transfemoral amputation?
Hip flexion, hip abduction, and hip external rotation; cannot WB thru end of residual limb, adaptation needed for energy expenditure, balance, and weight if prosthesis
Which motion is susceptible to contracture in knee disarticulation amputations?
Hip flexion; can WB thru end of residual limb, knee axis of prosthesis is below natural axis, gait deviations can occur from malalignment of knee axis
Which motions are susceptible to contractures in transtibial amputations?
Hip flexion and knee flexion; cannot WB thru end of residual limb, WB should be thru total residual limb, adaptations needed for balance
Why are adaptations required for Syme’s amputation?
To adapt for increased weight of prosthesis and due to diminished toe off during gait
What deformity tends to develop following transmetatarsal and Chopart’s amputations?
Equinus; also loss of balance, proprioception, WB surface, forefoot leverage
What directional patterns should you use for wrapping amputations?
Diagonal and angular patterns
