1.

Model A

Pull the pattern over the thumb all the way down, bring the edges together and stick them temporarily.

2.

Model B

Place the splint pattern on the dorsal aspect of the hand to fit precisely over the MCP joints. Mould the palmar portion proximal to the transverse skin crease. Close with a hook and look tape.

3.

Both models

Mould an Orfitube as shown in the drawing, and stick a Single Orfitube Adjuster to the splint base with an Orfitube in line with the index finger. Make a finger loop with Orfilight, stick an elastic to it and thread through the tube. Provide an adjustable sliding knot.

Mould a second Orfitube to be placed laterally along the index finger with the tip of the tube perpendicularly to the proximal phalanx when in full flexion. Attach a non-elastic cord laterally on the finger ring and tighten only when the index finger is in full extension.

Finishing and fixation:

  • Pay attention to the pressure on the ulnar styloid process.
  • Apply a broad velcro strap proximally under the forearm.
