Replantation of a Finger or Hand

Medically reviewed by Dr. Khalid Almutairi, Consultant Plastic Surgeon — updated 2026-08-13

Replantation is the reattachment of a completely amputated part — a finger or a hand — using microsurgery. It is among the most delicate operations in hand surgery and among the most time-sensitive: every hour that passes before circulation is restored reduces the chance of success.

Care is led by Dr. Khalid Almutairi, a consultant plastic and reconstructive surgeon, fellowship trained in hand surgery and microsurgery in Canada and the USA.

Amputation is an emergency — what to do right now

If an amputation has occurred, or a finger has lost its colour and warmth after an injury, the right place is an emergency department immediately — not a clinic appointment. On the way to the emergency department:

• Press on the bleeding point with a clean dressing; do not apply a strangling tourniquet.
• Wrap the amputated part in clean gauze moistened with saline or clean water, and place it in a sealed bag.
• Place the bag in a container of water with ice — never put the part directly on ice, and never submerge it in water.
• Always bring the amputated part with you, even if the damage looks severe; judging its viability is a medical decision.

Replantation and revascularization

Two situations are distinguished: replantation — reattaching a part that has separated completely — and revascularization — repairing the vessels of a part that remains partially attached but has lost its blood supply. Both rest on the same microsurgical principles, and both are races against time.

What does the operation involve?

An amputation divides everything at one level, so the operation rebuilds each layer in order: the bone is fixed first so length and alignment are stable; the tendons are repaired; the arteries and veins are sutured under the microscope to restore circulation; the nerves are repaired; then the skin. The operation can last many hours, and it is followed by close monitoring of circulation in the first days — any threat to the blood supply may require an urgent return to the operating room.

Can every amputated part be replanted — and should it be?

No. Feasibility and benefit depend on the mechanism of injury — a clean, sharp cut has better prospects than crushing or avulsion — the level of amputation, the duration without circulation, the condition and contamination of the tissues, the patient's age and health, and the function the part could realistically provide once reattached. In some cases the responsible decision is not to replant, and instead to repair the amputation in a way that gives a more useful hand. The goal is always a working hand, not merely a reattached part.

Recovery: surviving circulation is the beginning, not the end

The part staying alive is only the first stage. The journey to function then begins: bone heals over weeks; tendons need prolonged rehabilitation to regain glide; sensation returns slowly with nerve regeneration over months and may remain incomplete. Stiffness and cold intolerance are common after replantation, and secondary operations may be needed later — to free tendons or improve movement or appearance — and this is explained from the outset.

Limitations and risks

The foremost risk is failure of circulation despite repair — blockage of the artery or vein — and the replanted part may be lost partially or completely. Other risks include infection, stiffness, reduced sensation, chronic cold intolerance, and the need for further procedures. These limits are discussed frankly with every patient and family.

How long does an amputated part remain viable?

The time differs with the level of amputation and how the part is preserved; a finger kept cool tolerates longer than parts containing muscle. The practical rule is the same throughout: every early hour improves the chances, and the final judgement belongs to the medical team.

Will a replanted finger work as it did before?

It does not return exactly to what it was. Many patients regain useful function that improves with rehabilitation over months, with varying degrees of stiffness and reduced sensation. Realistic expectations are discussed for each case.

What if replantation is not possible?

The amputation is repaired in a way that preserves the best possible hand function, and reconstructive options are considered later — including, in selected cases of thumb loss, microsurgical transfer of a toe, which has its own dedicated page.

Medical-information notice

This is general information and does not replace medical assessment. Amputation and loss of circulation are emergencies managed immediately through emergency departments, and every case — including whether replantation is possible and where it is performed — is assessed individually and according to facility requirements.
