14

Where are incisions made for an amputation?

Distal to amputation level of bone to allow adequate soft tissue coverage

15

Where are veins/arteries clamped and ligated/sutered?

At the most distal point

16

How are nerves cut

Transsected under tension and allowed to retract.

17

What is a neuroma?

Hard bulbous end of a severed nerve. May cause pain

18

What is done to the end of the bone after an amputation?

approx. 15 cm (33-50% original length) although some report 20-60%

30

What is the benefits of a short residual tibia? Drawbacks?

improved comfort w/increased surface for weight bearing.
At a mechanical disadvantage
