Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with a sharp laceration to the volar aspect of the right index finger sustained [Time/Mechanism]. Patient reports inability to actively flex the distal interphalangeal (DIP) and proximal interphalangeal (PIP) joints. No reported numbness or paresthesia in the digital nerve distribution. No prior history of hand trauma or surgery.
Clinical Examination Findings
Right index finger: 2cm transverse laceration noted at the level of the proximal phalanx (Zone II). Tendon sheath integrity compromised. Active flexion of the FDP and FDS is absent. Passive range of motion is intact. Neurovascular status: Digital arteries patent, capillary refill <2 seconds. Sensation intact to light touch in radial and ulnar digital nerve distributions.
Treatment Protocol
Immediate surgical consultation for flexor tendon repair. Wound irrigated and dressed with sterile non-adherent gauze. Digital block performed for initial assessment. Splint applied in intrinsic-plus position to prevent tendon tension. Patient instructed on strict immobilization of the right index finger pending operative intervention.
