Answer :
Final answer:
The ortho condition described is a mallet finger, and the treatment for it involves splinting the DIP joint in extension to allow the tendon to heal properly.
Explanation:
The condition being described, which is due to the rupture or avulsion of the insertion of the extensor tendon and results in a flexion deformity of the DIP (distal interphalangeal) joint, is known as mallet finger. The appropriate treatment for a mallet finger is splinting the affected DIP joint in extension. This treatment helps to keep the tendon in a proper alignment for healing and prevents the finger from drooping, which is characteristic of this injury.
