What type of splint supports early PROM after extensor tendon repair in zones 3-6?

• A. Dynamic extension outrigger
• B. Static dorsal blocking splint
• C. Volar gutter splint
• D. Hinged elbow brace

Answer: (A)

The key idea is using dynamic, not static, protection to promote early motion after extensor tendon repair. After repairs in zones 3–6, the goal is to keep the tendon gliding and prevent adhesions while still protecting the repair. A dynamic extension outrigger splint provides a gentle, continuous extension force via an external mechanism (the outrigger and a tension element like a spring or rubber band). This setup supports active or assisted extension and allows controlled motion across the finger joints, so you can begin early PROM without overstressing the repaired tendon. A static dorsal blocking splint, by contrast, holds joints in a fixed position to limit motion, which limits early PROM. A volar gutter splint immobilizes the finger on the palm side and is used for immobilization, not promoting motion. A hinged elbow brace addresses the elbow, not the finger, and isn’t relevant for extensor tendon rehab in the hand.
