Deroyal LMB Spring PIP Finger Extension Assist can be used for boutonniere deformity and PIP extension limitations of 45 degrees or less. This Assist helps extend the PIP joint but does not interfere with the MP joint. To size, measure the distance on volar surface from MP crease to distal finger crease. When compared to the Spring Extension Splint series this series is shorter and stronger.

LMB Finger Extension Assist Highlights:

  • High quality Wire-Foam construction
  • Force at full flexion: 3.5-4 lbs
  • Force at full extension: 1/2 lb
  • Shorter than LMB Spring Finger Extension Assist
  • Latex free and Single patient use
