Question

Incision carried down to the right metacarpophalangeal joint. Incision was made directly over the capsule exposing the metacarpophalangeal joint. The extensor digitorum brevis tendon was exposed and a tendon graft taken from the extensor digitorum brevis tendon. A drill hole was made at the previous attachment of the ulnar collateral ligament and exiting dorsally on the proximal phalanx. Through this hole, the extensor digitorum brevis tendon was re-routed exiting the ulnar side of the joint. Two similar holes were then drilled on the metacarpal head of the thumb and the tendon graft was pulled through these two hole reestablishing ulnar collateral ligaments. With the reconstruction of the ulnar collateral ligament completed, the tendon was folded back on itself and sutured.

a. 26541-RT
b. 26542-RT
c. 26530-RT
d. 26540-RT

Answer 1

The narrative describes a surgical procedure on the metacarpophalangeal joint for ulnar collateral ligament reconstruction using an extensor digitorum brevis tendon graft.

Step-by-step explanation:

The student appears to be asking a question related to a surgical procedure involving the metacarpophalangeal joint, specifically the reconstruction of the ulnar collateral ligament using a graft from the extensor digitorum brevis tendon. The narrative describes a surgical technique where a drill hole is made to the attachment site of the ulnar collateral ligament and then the tendon graft is rerouted and sutured to reconstruct the damaged ligament. This procedure is important in the context of ligament injuries which can be common in athletes and others who perform repetitive movements that can damage these intrinsic ligaments of the hand and elbow such as the ulnar collateral ligament.
