A rare accessory extensor tendon in the hand, previously undescribed, caused unusual digit dysfunction. Surgical correction resolved the mechanical aberration, leading to an excellent patient outcome.
Area of Science:
- Anatomy
- Orthopedic Surgery
- Hand Surgery
Background:
- Accessory extensor tendons and slips of the hand are well-documented in anatomical literature.
- These anatomical variations typically do not cause functional deficits in patients.
Observation:
- A case report details a previously undescribed accessory extensor tendon of the hand.
- This specific anatomical anomaly resulted in an unusual mechanical aberration affecting a single digit.
Findings:
- The accessory tendon's aberrant mechanics were surgically explored and corrected.
- The surgical intervention successfully resolved the digital dysfunction.
Implications:
- This case highlights a rare cause of digital mechanical aberration due to accessory extensor tendons.
- Surgical correction can provide excellent functional outcomes for patients with this specific anomaly.
