Management of Dorsal Hand Injuries Prior to Hand Surgeon Evaluation
For dorsal hand injuries awaiting hand surgeon evaluation, immobilize the hand in a safe position with the wrist in 20-30 degrees of extension, the metacarpophalangeal (MCP) joints in 70-90 degrees of flexion, and the interphalangeal (IP) joints in full extension (the "position of function" or "intrinsic-plus position"), using a volar splint that extends from the fingertips to the mid-forearm.
Initial Wound Assessment and Protection
Critical Anatomical Considerations
- Dorsal hand wounds have a significantly higher association with underlying structural injuries compared to palmar wounds (58.5% vs 36.4%) 1
- More than 50% of dorsal wounds in zones 1,3,5,6, and 7 present with at least one underlying lesion 1
- Zone 3 dorsal wounds (overlying the proximal interphalangeal joints) have a 68% rate of major structural injuries including tendon damage and joint violations 1
Immediate Wound Care
- Cover any open wounds with a sterile, moist saline dressing to prevent tissue desiccation and contamination 2
- Apply a waterproof topical dressing as the first layer if there are minor lacerations 3
- Avoid direct pressure over obvious deformities or exposed structures 1
Splinting Technique and Position
Hand Position Rationale
The intrinsic-plus position prevents:
- Collateral ligament contracture at the MCP joints
- Volar plate contracture at the IP joints
- Extensor tendon adhesions on the dorsal surface
Splint Application Steps
Use a prefabricated volar splint or create a custom splint that immobilizes:
- Wrist: 20-30 degrees extension
- MCP joints: 70-90 degrees flexion
- PIP and DIP joints: Full extension (0 degrees)
Apply padding generously over bony prominences and between digits if multiple fingers are involved 2
Secure with elastic bandage wrap using gentle, even pressure:
- Start distally at the fingertips
- Wrap proximally toward the forearm
- Ensure the wrap is snug but not constrictive
- Check capillary refill and sensation after application
Leave fingertips exposed to monitor neurovascular status 2
Pain and Edema Management
Acute Phase Management
- Apply cryotherapy through a wet towel for 10-minute periods for short-term pain relief 4
- Elevate the hand above heart level continuously for the first 48-72 hours
- Avoid complete immobilization beyond the acute phase to prevent muscular atrophy and joint stiffness 4
Medication Considerations
- Provide appropriate analgesia based on pain severity
- Never inject corticosteroids into suspected tendon or ligament injuries, as this may inhibit healing and predispose to spontaneous rupture 4
Critical Warning Signs Requiring Immediate Evaluation
Neurovascular Compromise
- Absent or diminished capillary refill (>2 seconds)
- Numbness or tingling in specific nerve distributions
- Pallor or cyanosis of digits
- Increasing pain despite immobilization and elevation
Infection Risk
- Perform hand hygiene before and after every patient contact 2
- Monitor for signs of infection: increasing redness, warmth, purulent drainage, fever
- Wounds with visible contamination or significant tissue damage require urgent surgical evaluation 1
Special Considerations
Complex Injuries
- Dorsal wounds overlying joints (zone 3) have the highest rate of major structural injuries and warrant urgent hand surgeon evaluation 1
- Through-and-through injuries involving both dorsal and volar surfaces require complex reconstruction planning 5
- Injuries with bone exposure or suspected fractures need radiographic evaluation before definitive splinting 6
Timing of Specialist Evaluation
- All dorsal hand wounds should be evaluated by a hand surgeon regardless of initial appearance, given the high association with underlying structural damage 1
- Arrange hand surgeon consultation within 24-48 hours for closed injuries
- Open wounds, suspected tendon injuries, or neurovascular compromise require same-day or emergency evaluation 1
Patient Instructions
Activity Restrictions
- Keep the splint clean and dry
- Avoid using the injured hand for any activities
- Maintain strict elevation when not ambulating
- Activity modification to reduce movements that provoke pain while maintaining some wrist motion once cleared by hand surgeon 4
Follow-up Protocol
- Regular assessment of pain levels, range of motion, and functional improvement should guide progression of treatment 4
- Document and report any changes in sensation, color, or temperature of the hand
- Return immediately for signs of neurovascular compromise or infection
