Abstract
BACKGROUND: Trigger finger is a common condition, causing impaired gliding of the digital flexor tendons. Chronic inflammation is the usual cause, but acute trigger finger following partial tendon laceration has also been described. METHODS: We describe the case of a four year old girl who presented with inability to flex her index finger. Operative exploration revealed a closed partial rupture of the flexor digitorum profundus tendon, catching on the A2 pulley and preventing normal tendon gliding. RESULTS: Excision of the damaged section of tendon allowed normal gliding motion, and once the wound had healed the patient regained full painless motion. CONCLUSION: Acute trigger finger caused by partial flexor tendon injury is an uncommon but well-documented presentation. Surgical exploration not only confirms the diagnosis, but allows for excision of the damaged segment to return normal movement without compromising strength.
