What is a typical extensor tendon injury management principle to prevent adhesions?

• A. Immobilization for a prolonged period to protect the repair
• B. Early controlled motion after repair per protocol
• C. Immediate unrestricted movement as tolerated
• D. Complete immobilization until swelling subsides

Answer: (B)

Promoting tendon glide early after an extensor tendon repair is key to preventing adhesions. If the finger is kept still for too long, scar tissue forms between the tendon and surrounding tissues, which stiffens the joint and limits movement. The best approach uses motion early, but in a controlled way that follows a specific protocol to protect the repair while encouraging tendon excursion. This balance helps maintain glide, reduces adhesion formation, and supports better functional recovery. Immobilization or unrestricted movement without a structured plan can either promote adhesions or risk rupture, respectively.
