How to apply Thumb Spica Splint?

Making modifications:

  1. Before permanently attaching liner to splint, apply the splint (with liner in place) to check for fit. To trim or modify the splint, remove it and spot-heat it with a heat gun or in a heat pan of water at a temperature of 150° to 160° F (65°–70°C) for 30 seconds or until pliable. Heating the entire splint may cause it to lose its preformed shape. Polyform Light has a high degree of drape—for better results when modifying the material, shape it with stroking movements.
  2. Remove the backing from the adhesive strips on the back of the liner and apply liner to splint.

Apply straps - Forearm-Based Splint:

  1. With the splint on the patient, attach the two 11/2”-wide (3.8cm) foam straps around the forearm.

Both splints:

  1. With the splint on the patient, position the 1”-wide (2.5cm) strap across the dorsum of the hand and attach the self-adhesive loop on the strap to the ulnar side of the splint. Attach the self-adhesive hook coin to the radial side of the splint and fasten the strap.
