Surgical Options

First Dorsal Compartment Release

  1. Topographical marking
    1. Identify the radial styloid
    2. Mark a chevron 1cm proximal to the styloid process
  2. Incision and dissection
    1. Incise through full thickness skin
    2. Identify and retract the radial sensory nerve(s)
      1. Can be 1 to 3 branches
  3. Annular ligament release
