Extensor Tendon Laceration

ICD-10 Code
S66.221A

Plastic & Reconstructive Criteria for Extensor Tendon Laceration.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with a sharp laceration to the [dorsal aspect of the hand/digit]. Mechanism of injury: [e.g., glass, knife, machinery]. Patient reports immediate loss of active extension at the [MCP/PIP/DIP] joint. No reported neurovascular deficits, numbness, or paresthesia distal to the injury site. Tetanus status: [Up-to-date/Unknown].

Clinical Examination Findings

Inspection reveals a [linear/avulsion/complex] laceration over the [Zone I-VIII] extensor tendon. Active extension is absent or significantly lag-limited at the [joint]. Passive range of motion is intact. Neurovascular exam: Capillary refill <2 seconds, radial/ulnar pulses palpable, sensation intact to light touch in the distribution of the [radial/ulnar/median] nerve. No signs of infection or foreign body.

Treatment Protocol

Wound exploration performed under local anesthesia. Extensor tendon ends identified and approximated using [e.g., 4-0/5-0 non-absorbable monofilament suture] in a [e.g., Kessler/modified Bunnell] configuration. Skin closed with [e.g., 5-0 nylon] interrupted sutures. Immobilization in a [static/dynamic] splint in [neutral/extension] position for [4-6] weeks. Prophylactic antibiotics and pain management prescribed.
