Final answer:
The bicortical (inlay) button in the distal biceps kit is used to secure the distal biceps tendon to the bone and promote healing. Therefore, the correct option is 1.
Step-by-step explanation:
The purpose of the bicortical button is to anchor and attach the tendon to the bone. It is frequently utilised in surgical treatments to repair a ruptured distal biceps tendon. By using the bicortical button to secure the tendon after it has been passed through a bone tunnel, this procedure offers a dependable and stable fixation.
Restoring the anatomical relationship between the radial tuberosity and the distal biceps tendon will enable strong and appropriate elbow flexion and supination. The goal of this method is to speed up the healing process and shield the distal biceps tendon from further damage.
Therefore, the correct option is 1.
