Amputations: few basic rules

Function ….. function ….. function Upper limb: as long as possible Lower limb: support body weight

good muscle cover of stump: vastus medialis,

medial gastrocnemius

non-adherent non-painful scar: bevelled tibia proper length for stability: cut fibula 2 cm shorter

than tibia

neuroma: prevent
