When is splinting recommended for trigger finger?

Trigger finger occurs when a finger tendon does not glide smoothly through its surrounding pulley. The finger may click, catch, or lock, often with soreness near the palm at the base of the affected finger. A splint can limit the position that provokes catching and reduce repeated irritation while symptoms are assessed.

The support may be worn at night, during specific tasks, or for a clinician-selected period. Its design depends on which joint is catching and whether the finger can still move comfortably.

Use the splint as directed and avoid repeated forceful gripping, vibrating tools, or activities that make the finger catch. Keep nearby joints moving gently if comfortable, and do not force a locked finger open. A hand therapist can check the fit and suggest ways to modify work or household tasks.

Watch the skin under the support for pressure or rubbing. Numbness, tingling, swelling, or a change in finger colour should prompt a fit review. If the finger becomes stuck, support it without force and seek clinical advice.

Seek prompt care if the finger is locked, severely swollen, numb, pale or blue, or cannot move after an injury. Arrange an assessment when catching persists, pain interferes with sleep or daily tasks, or the splint causes skin injury. A clinician can discuss other options when support does not restore comfortable movement.

Ask which joint the splint should hold, when to wear it, which movements to limit, how to keep the hand mobile, and what should happen if the finger continues to lock.
