Disposition
Level of care decisions
Disposition pathways
Immediate hand surgery consultation in ED
Thumb injury

Exposed joint or tendon
Unstable fracture
Significant contamination requiring OR washout
Transfer to replantation center
Candidate for replantation with viable part and acceptable ischemia time

Pain controlled on oral regimen
Reliable follow-up in 24 to 72 hours
Admission
Need for operative management within same hospitalization
Inadequate pain control
Social barriers to wound care and follow-up
Follow-up timing
Reassessment plan
Hand surgery clinic within 24 to 72 hours for most cases
Dressing check within 48 hours if bulky or hemostatic packing used
Earlier return plan for recurrent bleeding or perfusion change
Treatment
Wound care strategy selection
Management options
Secondary intention healing
Small pulp loss with no exposed bone
Many distal injuries with acceptable contour outcome
Primary closure
Tension-free closure possible without compromising perfusion
Minimal tissue loss
Revision amputation
Exposed distal phalanx with insufficient soft tissue coverage
Bone shortening to allow soft tissue coverage when appropriate
Flap reconstruction referral
Larger tissue loss requiring durable coverage
Exposed bone requiring vascularized tissue
Replantation consideration
Thumb amputation preference
Multiple digits preference
Distal single-digit in selected patients and centers
Hemostasis and dressing
Local measures
Pressure dressing principles
Nonadherent layer over wound
Bulky gauze for tamponade
Splint to protect and reduce shear
Topical hemostatic agents
Oxidized cellulose or gelatin sponge as adjunct
Avoid tight circumferential wrap at digit base
If persistent bleeding
Re-explore for identifiable vessel
If arterial spurting, urgent surgical control pathway
Anesthesia and analgesia
Digital anesthesia
Digital block technique
Two-sided web space injection
Aspirate before injection
Total volume minimized to avoid compartment effect
Lidocaine 1% without epinephrine
Typical adult total dose 5 mL to 10 mL divided injections
Maximum lidocaine dose 4.5 mg/kg without epinephrine
Bupivacaine 0.25% option
Longer duration analgesia
Maximum bupivacaine dose 2.5 mg/kg
If epinephrine-containing anesthetic used
Avoid in severe peripheral vascular disease or vasospastic disease
Phentolamine rescue plan available for prolonged blanching
Systemic pain control
Acetaminophen
Adult 650 mg to 1000 mg PO every 6 to 8 hours
Maximum 4000 mg per 24 hours
If liver disease, lower maximum
Ibuprofen
Adult 400 mg to 600 mg PO every 6 to 8 hours
Maximum 2400 mg per 24 hours for short course
Avoid in CKD or GI bleed risk
Opioid for breakthrough pain
Hydromorphone PO
1 mg to 2 mg PO every 4 to 6 hours as needed
Avoid coadministration with sedatives
Oxycodone PO
5 mg PO every 4 to 6 hours as needed
Lowest dose shortest duration strategy
Antiemetic if opioid used
Ondansetron ODT
4 mg PO every 8 hours as needed
QT prolongation risk review
Antibiotics
Antimicrobial strategy
Low-risk clean distal fingertip without exposed bone
No routine antibiotics for uncomplicated clean wounds in many pathways
Shared decision based on contamination and follow-up reliability
Exposed bone or open fracture concern
First-generation cephalosporin typical
If delayed presentation or heavy contamination, broaden coverage
Suggested regimens
Cephalexin PO
500 mg PO every 6 hours for 3 to 5 days
If penicillin anaphylaxis, avoid cephalosporin depending on local policy
Clindamycin PO
300 mg to 450 mg PO every 6 to 8 hours for 3 to 5 days
C difficile risk counseling
Amoxicillin-clavulanate PO for bite contamination
875 mg PO every 12 hours for 3 to 5 days
If allergy, alternative bite regimen per local guidance
Evidence framing
Antibiotics for grossly contaminated open injuries supported by expert consensus
Routine antibiotics for clean distal fingertip injuries has mixed evidence and often not required
Tetanus prophylaxis
Immunization
Clean minor wound
Booster if last dose 10 years or more
Tetanus immune globulin if unimmunized
Dirty or contaminated wound
Booster if last dose 5 years or more
Tetanus immune globulin if unimmunized or unknown status
Surgical consultation and replantation
Consultation elements
Candidate assessment
Patient goals and occupational needs
Comorbid vascular risk
Mechanism severity
Replantation general favoring factors
Thumb
Multiple digits
Pediatric cases
Clean sharp cut
Replantation general limiting factors
Prolonged warm ischemia beyond targets
Severe crush or avulsion with long vessel injury
Unstable patient or major competing injuries
Special Populations
Pregnancy
Pregnancy considerations
Imaging
Radiographs acceptable with shielding and clinical necessity
Avoid CT unless clear added value
Analgesia
Acetaminophen preferred first-line
NSAID avoidance in later pregnancy per obstetric guidance
Antibiotics
Beta-lactams commonly used when indicated
Avoid tetracyclines and fluoroquinolones when alternatives exist
Consultation
Obstetric coordination if surgical pathway planned
Geriatric
Geriatric considerations
Vascular risk
Atherosclerotic disease with higher ischemia risk
Anticoagulant use with higher bleeding risk
Healing risk
Diabetes prevalence and neuropathy
Malnutrition risk
Medication safety
NSAID renal and GI risk
Opioid fall and delirium risk
Disposition
Lower threshold for admission if wound care barriers
Pediatrics
Pediatric considerations
Replantation bias
Higher regenerative potential and functional recovery
Lower threshold for microsurgery consultation when part available
Growth plate issues
Distal phalanx physeal injury consideration
Seymour fracture pathway consideration
Pain control
Weight-based dosing
Procedural anxiety planning

Weight-based antimicrobial dosing when indicated
Immunization record verification
Background
Epidemiology
Epidemiology
Common mechanisms
Door crush injuries
Kitchen knife injuries
Power tool injuries
High-impact digit importance
Thumb and index critical for pinch
Middle finger critical for grip span
Complication frequency themes
Nail deformity common when germinal matrix injured
Hypersensitivity common early after healing
Pathophysiology
Pathophysiology
Tissue components at risk
Pulp pad with sensory end organs
Nail plate and nail bed complex
Distal phalanx tuft
Vascular considerations
Digital arteries terminal branches in distal digit
Crush and avulsion causing intimal injury beyond visible zone
Pain mechanisms
Exposed nerve endings in pulp
Neuroma formation risk in transected digital nerves
Therapeutic Considerations
Therapeutic principles
Goals
Durable sensate tip
Preserved length when feasible
Nail function and cosmesis when possible
Secondary intention rationale
Granulation and epithelialization effective for small distal defects
Avoids flap morbidity in select cases
Bone management rationale
Bone shortening sometimes required for soft tissue coverage
Excess shortening risks hook nail deformity
Replantation tradeoffs
Longer operative time and rehabilitation
Thrombosis risk and need for monitoring
Potential for superior length and nail preservation

Elevation and activity
Hand elevated above heart as much as possible for 48 to 72 hours
Avoid soaking in water until cleared
Splint protection if provided
Pain control plan

Opioid only for breakthrough pain if prescribed
Follow-up
