A patient sustained an accidental nail trauma resulting in a partially lifted nail that remains attached but is bleeding profusely; what is the appropriate next step in management?

Management of Partially Avulsed Nail with Profuse Bleeding

Immediately apply direct manual compression to the bleeding nail bed to achieve hemostasis, then perform a thorough examination under local anesthesia with a digital block to assess the extent of nail bed laceration and any underlying distal phalanx fracture. 1, 2

Immediate Hemorrhage Control

• Apply firm direct pressure to the wound for several minutes to control the profuse bleeding—this is the first-line intervention for any open bleeding wound 1
• Do not waste time attempting complex interventions before achieving basic hemostasis, as every minute of delay in controlling bleeding increases morbidity 1
• Once bleeding is controlled, prepare for proper examination and definitive management 2, 3

Essential Clinical Evaluation

After achieving hemostasis, perform the following assessment:

• Administer a digital block with local anesthetic to allow pain-free, thorough examination of the injury 2, 3
• Apply a finger tourniquet (using a sterile glove finger or Penrose drain at the base of the digit) to create a bloodless field for adequate visualization 2
• Remove the partially lifted nail plate completely to expose and directly visualize the underlying nail bed laceration 2, 4
• Assess for distal phalanx fracture with physical examination and plain radiographs, as nail bed injuries frequently involve underlying bone fractures 2, 5, 4
• Perform a comprehensive neurovascular examination: check capillary refill, two-point discrimination compared to an uninjured digit, and assess range of motion 2

Common Pitfall to Avoid

• Never assume the extent of nail bed injury based solely on external appearance—blunt trauma often causes more extensive nail bed lacerations than initially apparent, and failure to remove the nail plate and directly visualize the injury leads to inadequate treatment and permanent deformity 4, 6
• Inadequate or delayed treatment of nail bed lacerations results in chronic pain, nail dystrophy, and functional impairment that is difficult or impossible to correct secondarily 2, 5, 6

Definitive Management Algorithm

Once the injury is fully visualized:

• If a nail bed laceration is present (which is highly likely given the mechanism), repair it with absorbable 6-0 or 7-0 suture or octyl-2-cyanoacrylate tissue adhesive 3
• In most cases, do not replace the nail plate or stent the nail fold—modern evidence shows this is unnecessary for most simple lacerations 3
• If a distal phalanx fracture is present, determine whether it requires stabilization; fractures involving the germinal matrix or requiring stabilization mandate nail bed exploration and repair 2
• Seymour fractures (open physeal fractures in children with nail bed interposition) require urgent operative management to prevent growth arrest and infection 2

Post-Repair Care

• Apply a non-adherent dressing and protective splint if a fracture is present 2, 3
• Prophylactic antibiotics are indicated if there is an associated open fracture 2
• Arrange follow-up within 5-7 days to monitor healing and watch for signs of infection 2
