- Consider intervention for hematoma >50% of nail bed
Types
- Simple - no nailbed dislocation, no e/o open fracture
- Complex - beyond simple
Differential Diagnosis
Distal Finger (Including Nail) Injury
- Distal interphalangeal dislocation (finger)
- Distal phalanx (finger) fracture
- Finger amputation
- Fingertip avulsion
- Finger infection
- Nailbed laceration
- Nail avulsion
- Subungual hematoma
Hand and finger injuries
- Distal finger
- Other finger/thumb
- Boutonniere deformity
- Mallet finger
- Jammed finger
- Jersey finger
- Trigger finger
- Ring avulsion injury
- De Quervain tenosynovitis
- Infiltrative tenosynovitis
- Metacarpophalangeal ulnar ligament rupture (Gamekeeper's thumb)
- Hand
- Wrist
- Drummer's wrist
- Ganglion cyst
- Lunotriquetral ligament instability
- Scaphoid fracture
- Extensor digitorum tenosynovitis
- Compressive neuropathy ("bracelet syndrome")
- Intersection syndrome
- Snapping Extensor Carpi Ulnaris
- Vaughn Jackson syndrome
- General
Management
Simple
- Trephination
- Handheld cautery works best - no anesthesia is required
- Alternatively a needle spun in a drilling fashion
- Sharp object (i.e. safety pin) heated with flame in an austere environment
- If a fracture is present, the digit should be splinted
- Instruct pts to soak affected finger in warm water BID-TID x7d
Complex
- Nail removal only recommended if there is associated nail avulsion or nail fold disruption
