Describe Amputation Stump Complications in detail.

General Surgery · Final Professional

Overview

A well-shaped, healthy stump (residual limb) is essential for successful prosthetic use, and many post-amputation problems arise from the stump itself. These complications may be early (in the healing period) or late.

Timing	Complication
Early	Haematoma; wound infection; skin-flap / stump necrosis; reactionary haemorrhage
Late	Painful neuroma; phantom limb pain; stump (pressure) ulcer; flexion contracture; bony spur

Key Problems

A neuroma (a tangle of regenerating axons at the cut nerve end) is unavoidable, but if it lies at a pressure point it becomes painful — hence nerves are cut cleanly under tension so they retract away from the scar. A flexion contracture of the joint above the amputation (e.g. Knee or hip) develops if the stump is left in a flexed position, and can prevent prosthetic fitting. A poorly fitting socket causes stump ulceration. Ischaemic stumps (vascular disease) are prone to non-healing and necrosis.

CLINICAL PEARL

Prevent the two most disabling stump problems by design: place the scar and neuroma away from pressure areas, and prevent flexion contractures from day one by correct positioning and early physiotherapy.

Clinical Note

Because so many stump problems are avoidable, the emphasis is on surgical technique and early rehabilitation: careful flap design and haemostasis prevent haematoma and necrosis; cutting nerves cleanly under tension keeps the neuroma out of harm’s way; and correct positioning with early physiotherapy prevents the flexion contractures that can otherwise make a limb impossible to fit with a prosthesis.

CLINICAL PEARL

A good operation and good early care prevent most stump problems: design flaps for a padded, mobile scar away from pressure, cut nerves under tension so the neuroma retracts, and start positioning and physiotherapy at once to head off flexion contractures.

DANGER / REMEMBER

An ischaemic (vascular-disease) stump is especially prone to non-healing and necrosis, so in these patients the amputation level must reach tissue with a blood supply adequate to heal — amputating too low to ‘save length’ risks a breakdown that forces re-amputation at a higher level.

A painful neuroma is a common cause of prosthetic intolerance.

KEY POINT

Key points TO remember

Healthy stump is essential for prosthetic use; complications early vs late.
Early: haematoma, infection, flap/stump necrosis, haemorrhage.
Late: painful neuroma, phantom pain, stump ulcer, flexion contracture.
Prevent: nerves cut under tension (retract), scar off pressure areas, avoid contractures early.
