Finger amputation refers to the loss of part or all of a finger, most often this is secondary to trauma. This is a surgical emergency that can lead to significant functional impairment and long-term disability. Finger replantation aims to restore form and function by reattaching the amputated portion to the hand. Time is a critical factor in the success of replantation, with current recommendations of 12 hours for warm ischaemia and 24 hours for cold ischaemia (1). Patients should be referred to the hand surgery team urgently, as timely intervention is crucial for optimal outcomes (1). This article will focus on the initial assessment and management of finger amputations. Not all amputated digits are appropriate for replantation, and it is important to manage patient expectations appropriately and avoid promises on the hand surgery team’s behalf.Your Attractive Heading

Epidemiology

• Epidemiological data of finger amputations in the UK is limited; however, 3495 cases were last reported in 2014-15 (2)
• Amputations have a bimodal incidence rate with differing mechanisms of injury by age:
  • The first peak is from age 0-4, with the most common cause being doors closing on the finger. These rates are slightly higher in the male population.
  • The second peak is from 65-74, with power tools and motor items being the most common cause. These rates are much higher in males in this age group (3).

Assessment

Initial assessment should follow the ATLS guidelines to manage life-threatening injuries first and stabilise the patient. Focused history, hand examination and relevant investigations should take place as appropriate (some history and investigations take place during ATLS).

History

• Mechanism of injury (sharp, crush, avulsion)
• Time of injury (to estimate ischaemic time)
• Number of digits affected
• Sequence of events
  • Pre, during and post trauma
• First aid provided at the scene
  • Wound irrigation, tourniquet use
• Preservation of the amputated portion

Past medical and drug history:

• Comorbidities – can affect healing, fitness for surgery or anaesthesia
  • Diabetes, hypertension, heart and liver disease, coagulopathies, HIV, cancer (5,6)
• Regular medications
  • Anticoagulants may need reversal treatment
  • Immunosuppressants will affect healing outcomes
• Tetanus status
  • Patients may require boosters, and NICE guidelines should be adhered to.
• Allergies

Social history:

• Hand dominance
• Occupation and hobbies
  • This can influence the operation performed, especially in cases where reconstruction of the hand is essential for work
• Living situation:
  • May affect discharge considerations and immediate support required if the patient is solely responsible for dependents or lives alone.
• Smoking status
  • This negatively impacts wound healing (7)

Examination

• A thorough examination of the proximal portion and amputated portion is necessary for pre-operative planning
• Examine the proximal stump for:
  • Level of amputation
  • Tissue damage pattern
    • Sharp – clean margins
    • Crush/avulsion – extensive soft tissue damage
  • Soft tissue condition
    • Looking for devitalised tissue, tendon exposure, and bone protrusion
  • Wound contamination
  • Bleeding
    • Active arterial bleeding is suggestive of intact vasculature; absence may indicate vascular injury or vasospasm
  • Bone integrity
    • Palpate for bone fragments or step deformity
  • Preserved function of proximal stump
  • Full neurovascular examination is essential
• Amputated portion for:
  • Tissue viability
    • Colour, turgor, signs of drying or necrosis
  • Contamination
  • Level of amputation
    • Whether it matches the stump
  • Tendon, vessel and nerve ends
    • Note their condition and the length available for repair

Investigations

• Routine bloods
  • FBC, U&E, LFT, CRP, Clotting screen, Group and Save + Crossmatch
• X-rays – anteroposterior, lateral and oblique views of both the amputated portion and the proximal stump
  • This helps assess the level of amputation and aids pre-operative planning

Management

After completion of primary and secondary surveys as per ATLS protocol, immediate management would include (8):

• Ensure appropriate preservation of the amputated digit(s)
• Haemostasis
  • Direct pressure or tourniquet application is usually adequate
  • Suturing of any vessels should only be completed by an experienced surgeon
• Tetanus prophylaxis
  • NICE guidelines provide advice on when this is indicated (10)
• Prophylactic antibiotics
• Analgesia
• Medical photography
• Escalate early to the specialist hand surgery team

Definitive management

• Definitive management should only be discussed by a hand surgeon, as injury and patient factors affect the optimal management choice.
• Finger replantation is a potential definitive treatment; however, patients must be fully counselled and informed of:
  • Long-term commitment to rehabilitation
  • Risk of complications such as incomplete restoration of hand function or the need for further operations
  • Post-operatively, the patient must commit to stopping smoking and an extensive rehabilitation protocol
• The surgeons must carefully consider each case on an individual basis before offering replantation. Table 1 summarises the current agreed clinical indications and contraindications (11,12)

Table 1: Indications and contraindications for digit replantation

• The other definitive management option would be terminalisation of the affected digit(s)
  • This option does not offer restoration of function, but recovery is much faster, which may be preferable to the patient

Complications

Acute:

• Replantation failure
  • This can be due to arterial thrombosis or venous congestion and will usually require further operations to salvage the replanted digit
• Infection
• Bleeding and haematoma (13)

Chronic:

• Joint stiffness and contracture
  • Common due to immobilisation, scarring or tendon adhesion
  • Often requires extensive hand therapy and sometimes surgical release
• Sensory deficit/changes
  • Incomplete nerve regeneration can lead to reduced or altered sensation
  • Commonly, patients can complain of cold intolerance
• Neuroma formation
  • This can lead to chronic pain or hypersensitivity
• Chronic pain
• Aesthetic concerns
  • Bulkiness, scarring or nail deformity may affect patient satisfaction
• Psychological impact
  • Anxiety, depression or post-traumatic stress can follow traumatic amputations and complex recovery (13)

Conclusion

• Finger amputations are surgical emergencies that require prompt and systematic assessment to optimise functional outcomes
• Replantation is the gold-standard definitive treatment in selected patients, particularly those with thumb or multiple finger amputations and when ischaemic times are within acceptable limits
• Early referral to specialist hand surgery teams and correct preservation of the amputated digit are critical to replantation success
• Definitive management must be individualised, considering injury mechanism, patient comorbidities, lifestyle factors and the functional value of the digit
• Complications are common, and patients must be fully informed of the long rehabilitation process and potential outcomes
