From: Traumatic index extensor tendon attenuation mimicking closed tendon rupture: two case reports
a. Preoperative extension loss of the MP joint of the left index finger. b. Three-dimensional CT imaging showing the slackness of the index EDC and EIP tendons. c. Intraoperative finding of the attenuated EIP tendon (white triangle) and partial tear of the index EDC tendon (white arrow). Shortening of the attenuated EIP tendon and tendon transfer of the index EDC to the middle EDC tendon. d. Postoperative full extension of the MP joint of the left index finger
