Which statement best explains immobilization after Zone 2 flexor tendon repair in children?

• A. Helps prevent tendon rerupture and protects repair
• B. Accelerates tendon healing by early motion
• C. Prevents nerve injury
• D. Increases scar tissue formation for stability

Answer: (A)

Immobilization after Zone II flexor tendon repair is used to protect the repair during the early healing phase. The sutured tendon ends are vulnerable to gapping or rupture from even gentle loads of finger movement, so keeping the finger still reduces tension on the repair and minimizes the risk of rerupture. In children, this protection is especially important because active use and play can place unpredictable stresses on the repair. After enough initial healing has occurred, a carefully graded, controlled motion program is introduced to promote tendon gliding and prevent stiffness from scar formation. Early motion might compromise the repair, and immobilization is not specifically aimed at preventing nerve injury or deliberately increasing scar tissue for stability.
