Wrist & hand injury: documentation that holds up
Hand injuries are high-morbidity and high-liability — open finger injuries are among the most-litigated ED diagnoses. The defensible chart documents the neurovascular and tendon exam (through full range of motion), and recognizes the deceptively benign emergencies: the injection injury, the occult scaphoid, and the fight bite.
01What's at stake
Several hand injuries look trivial and aren't: a high-pressure injection puncture is a surgical emergency, an occult scaphoid fracture is normal on up to 20% of initial films, a knuckle laceration is a fight bite, and a retracted tendon end hides out of a neutral-position wound. Missing the neurovascular/tendon exam is the recurring failure.
02Can't-miss injuries
- High-pressure injection injury — innocuous puncture; IV antibiotics + emergent hand surgery (debridement within ~6h).
- Hand compartment syndrome — pain out of proportion, tense compartments, intrinsic-minus posture.
- Occult scaphoid fracture — snuffbox tenderness; thumb spica + repeat films/MRI even if x-ray normal.
- Perilunate/lunate dislocation — high-energy FOOSH; the lateral film ("spilled teacup"); often missed.
- Fight bite — laceration over the MCP; joint/tendon involvement, Eikenella; don't close primarily.
- Tendon/nerve/vessel injury — flexor (FDP/FDS), mallet/jersey finger, gamekeeper's thumb.
03The exam (the load-bearing note)
- Neurovascular — two-point discrimination for radial/median/ulnar, motor (incl. Froment), Allen test; capillary refill/pulse-ox are weak for arterial injury. → document per nerve
- Individual tendon testing — FDP and FDS separately; resisted extension.
- Explore the wound through full range of motion in a bloodless field to the base — a retracted tendon sits out of the wound at rest. → full ROM
- Look for rotational deformity (scissoring on flexion).
Skip the typing
Work the case in the Wrist & Hand Injury Workup — it records the snuffbox exam, the neurovascular hand exam, scaphoid/arc imaging, and the thumb-spica plan, and assembles an MDM that documents the can't-miss injuries were addressed.
04Imaging & management
- X-rays with dedicated views (scaphoid for snuffbox tenderness, Roberts for thumb, 3-view for fight bite/metacarpals); CT/MRI for occult fracture; ultrasound for tendon or radiolucent foreign body.
- Scaphoid precautions: snuffbox tenderness with normal films → thumb spica, hand-surgery referral, repeat films at 10–14 days.
- High-pressure injection: IV antibiotics, immediate hand surgery — do not be reassured by a benign appearance.
- Fight bite: amoxicillin-clavulanate, leave open, hand surgery for joint/tendon involvement.
- Splint in the intrinsic-plus position (mallet finger = DIP-only in extension, not buddy-tape); lidocaine with epinephrine is safe in digits (except ischemia risk); refer tendon repairs within ~7 days.
05What to document
06Where charts fail
- Exploring/clearing a wound without full range of motion — missing a retracted tendon.
- Calling an injection injury benign, or not consulting hand surgery emergently.
- "Wrist sprain" with snuffbox tenderness and a normal x-ray (missed scaphoid) — no spica/repeat imaging.
- Closing a knuckle laceration without recognizing the fight bite.
- Documenting "neurovascularly intact" without the per-nerve/tendon exam, or missing compartment syndrome.
