Which statement aligns with avoiding restriction of motion in non-affected joints?

• A. Include all joints to maximize immobilization.
• B. The splint should be fabricated from rigid metal.
• C. Avoid restricting ROM of non-affected joints.
• D. Rounded edges.

Answer: (C)

Preserving motion in joints that are not injured is essential during splinting to prevent stiffness and maintain overall hand function. The best approach is to avoid restricting ROM in non-affected joints, so those joints can move freely while the injured areas are stabilized. This supports tendon glide, proprioception, and the prevention of contractures, keeping the hand as functional as possible during healing.

Immobilizing all joints would lead to widespread stiffness and loss of function. Choosing a splint with rigid metal material isn’t inherently wrong for support, but if it unnecessarily restricts motion in joints that should stay mobile, it contradicts the goal of preserving non-affected ROM. Rounded edges improve comfort and skin tolerance, which is important, but they don’t address the core aim of keeping non-involved joints free to move.
