Flashcards in LE Amputation Deck (23)
What is a Lisfranc's amputation?
Amputation through tarsometatarsal junction
What ABI indicates mild PAD?
What is considered long, standard and short AKA?
Long = >60% residual limb
Standard = 35-60% residual limb
Short = <35% residual limb
MCC of amputation ages 15-50
What is considered a long, standard and short BKA?
Long = >50% residual limb
Standard = 20-50% residual limb
Short = <20%
Gold standard imaging test for PAD
Intraarterial contrast angiography
MCC of amputation in ages 0-5
What's the shortest BKA you can have with residual limb still being functional?
1cm below tibial tuberosity
What is a syme's amputation?
Hip disarticulation vs hemipelvectomy vs hemicorpectomy
Hip disarticulation = pelvis remains in tact
Hemipelvectomy = resection of lower half of pelvis
Hemicorpectomy = amputation of both lower limbs and pelvis
Myodesis vs myoplasty
Myodesis is when muscle is sutured to bone.
Myoplasty is when muscles are sutured to each other
What is considered too high of an ABI and may be considered abnormal?
>1.3. May indicates calcified noncompressible vessels
What are 2 unsatisfactory levels of amputation for a BKA?
1. Amputation through distal 2/5 of tibia (60% of residual limb) - below the gastroc-soleus
2. Very short BKA - above the tibial tuberosity
What ABI indicates severe PAD
What ABI indicates moderate PAD?
What is considered an unsatisfactory AKA level?
Very short AKA with Amputation through just below lesser trochanter
MCC of amputation in ages 5-15
Cancer or trauma
When a patient has dysvascularity and myodesis is contraindicated, what is the procedure of choice?
What is a contraindication to myodesis?
If ABI screening for PAD is abnormal, what test can be done to localize the lesion?
Doppler velocity waveform analysis
What is a Chopart amputation?
Amputation through the tarsal bones, sparing the calcaneus and talus
What is considered normal ABI?
0.9 - 1.3
