Sterile matrix injury affecting nail adherence and surface
Subungual hematoma pressure physiology
Pain driven by pressure under nail plate
Trephination relieving pressure
Distal phalanx fracture linkage
Nail bed laceration bridging to bone exposure behavior
Open fracture infection risk concept
Therapeutic Considerations
Treatment rationale
Trephination value
Pain relief
Low complexity when nail folds intact
Nail bed repair value
Nail growth surface restoration
Nail deformity risk reduction
Nail fold stenting value
Prevents adhesion of eponychial fold
Maintains nail plate track
Antibiotic rationale in open fracture behavior
Bone exposure risk in distal phalanx fracture with nail bed laceration
Contamination burden guiding regimen breadth
Evidence framing
Trephination acceptable for painful subungual hematoma with intact nail folds when no displaced nail plate
Hand surgery consensus supports meticulous nail bed repair for matrix injuries
Antibiotic practice varies for tuft fractures with nail bed laceration
Local protocol alignment recommended
Patient Discharge Instructions
copy discharge instructions
Discharge instructions
Wound care
Keep dressing clean and dry for 24 to 48 hours
After 24 to 48 hours, gentle soap and water if advised
Nonadherent dressing changes as instructed
Elevation and swelling control
Hand elevation above heart
Ice over dressing in short sessions
Pain plan
Acetaminophen as directed
NSAID as directed if safe
Avoid exceeding maximum daily doses
Splint care
Keep splint dry
Loosen wrap if increasing tightness
Activity limits
No heavy lifting or contact use of injured finger
Splint adherence if fracture present
Infection warnings
Increasing redness
Increasing warmth
Pus or foul drainage
Fever
Neurovascular warnings
Increasing numbness
Increasing tingling
Finger turning pale or blue
Worsening pain not controlled by medication
Hematoma warnings after trephination
Rapid re-accumulation of pressure pain
Persistent bleeding soaking dressings
Follow-up plan
Repair follow-up in 5 to 10 days
Earlier review if dressing issues or worsening symptoms
