Extensor tendon rupture of the index finger secondary to avascular necrosis of the scaphoid: a case report.
We report on a 74-year-old man with extensor indicis proprius (EIP) tendon rupture secondary to avascular necrosis and collapse of the scaphoid. The collapsed scaphoid was removed, followed by 4-corner fusion and tendon transfer of the extensor digiti minimi to the EIP. At the 3-year follow-up, the patient was painfree and had full extension of his left index finger, with proper alignment of the carpal bones and union of the 4 bones.
