⚠️ A case of a power grinder kickback towards the back side of the patients arm causing this severe injury! Upon closer inspection, you can see extensor tendons protruding from the wound. Extensor tendon lacerations of the hand and fingers are quite common constellations of injuries. Because of the superficial location of the extensor tendons in the wrist and hand, the laceration often easily directly observed on physical examination with manipulation of the overlying skin. The underlying joint is passively flexed and extended for full visualization of the injury area. Once the decision for surgical intervention has been made, the general principles of definitive wound debridement, early tendon repair, and early range of motion hand therapy guide the treatment plan for all extensor tendon injuries.
