Answer: High pressure injection injury
- Hand surgery consultation
- Immobilization and elevation of affected limb
- Tetanus prophylaxis
- Broad spectrum antibiotics
- Effective analgesia
- Definitive treatment is early surgical decompression and debridement of injected area
Pearls and Pitfalls
- Prognosis depends on composition of injected material, location, pressure (PSI), and time to surgical intervention
- Often overlooked due to appearance of exterior wounds but are true surgical emergencies
