Example of a simple splint for trigger finger that can be easily made using alumi-foam splinting strips. Measure from the proximal palm to the distal aspect of the middle phalanx, cut to length, trim and smooth sharp edges, and place a slight bend (about 10 degrees) under the MCP joint. Tape it to the finger and palm. This restricts flexion at the MCP joint but allows motion at the DIP joint.
