Upper Limb Amputations Flashcards
ray amputation can give better results than a partial finger
amputation.
T
Length and position are more important than motion in Thumb Amputation
T
ifthe amputation
is through the middle phalanx, distal to the insertion of the flexor
digitorum superficialis tendon, then preservation ofthe digital length
is often recommended to maintain motion and strength through
the proximal interphalangeal joint
T
amputation is
through the middle phalanx, proximal to the insertion of the flexor
digitorum superficialis, preserving the short middle phalanx stump is
often a hindrance because there will be no active flexion through the
proximal interphalangeal joint.
T
Proximal digital amputations through the proximal phalanx and
more proximal can result in difficulty in holding small objects what is the option of managment
For
improved function andappearance, ray amputation may be preferred.
This narrows the hand width, resulting in 40% less grip strength
Digital transposition can be performed; for example, moving an
intact second ray over to the base of the third metacarpal after ring
finger ray amputation
T
Symptomatic neurornas develop in 10% of patients with major
limb amputations
F Symptomatic neurornas develop in 25% of patients with major
limb amputations
Phantom pains are ongoing
painful sensations felt corning from the amputated limb and may
occur with or without neurornas
T
centro-centralization technique to divide the nerve 5 to 10 mm
proximal to the neurorna and performing an additional repair as
an autologous transplantation
T
Target muscle reinervation techniques appear to be more reliable solutions, providing amputated nerves with new functions and
preventing neuroma recurrence
T
a transhurneral amputation, for example, the
median nerve can be coapted to the medial head of the biceps and
the ulnar nerve can be coapted to the brachialis (hand close signals).
The distal radial nerve can be coapted to the lateral head of the triceps (hand open signal)
T
Patients can resume wearing their existing prosthesis 4 to 6 weeks
after TMR
