Surgical techniques WEEK 2 Flashcards
1
Q
factors affecting level of amputation
A
- vascular disease
- postoperative function is considered
- disarticulations
- traumatic amputation
2
Q
myoplasty
A
- attachment of anterior and posterior compartment muscles to each other over the end of the bone
- MUSCLE TO MUSCLE
- better in presence of ischemia
3
Q
myodesis
A
- anchoring of muscles to bone
- increased stability and muscular control
4
Q
skin flaps
A
- broad as the distal end of the limb
shaped to allow corners to retract smoothly - drains are utilized just under incision for removal of excess fluid
5
Q
skin flaps: open amputation
A
- utilized if infection present or not enough tissue to provide good closure initially
6
Q
skin flaps: closed amputation
A
- equal length anterior/posterior flap (when covering bone length or when primary healing is not a concern, flaps shaped to reduce “dog ears” at corners)
- long posterior flap (used when vascularity is of concern or when more padding is needed)
7
Q
skew sagittal flaps (closed amputation)
A
- used in severe dysvascular cases: salvage’s saphenous arteries
8
Q
Transtibial (below knee)
A
- desirable length is controversial
- shortest level compatible with knee function= tibial tubercles (attachment for quads)
9
Q
in general for a BKA the fibula is cut 1 cm _____ than tibia for limb shaping.
A
- shorter
- also bridged together to keep fibula from moving as much
10
Q
Which is preferred, a cylindrical or conical shape?
A
cylindrical- leave fibula as long as they can, dispersing force easier to different types of sockets
11
Q
transfemoral (AKA)
A
- most common for individuals with poor circulation or gangrene of foot/ankle
- greater circulation above the knee
- need energy to ambulate w TKA prothesis
- Reasons: trauma, gangrene that has extended to knee, circulatory status indicating poor chance of healing at transtibial level
