1 Innovative Splinting options for the Thumb MP joint Kathleen Snelgrove OTR/L, CHTUniversity Orthopedics Inc.Providence, RI
2 Thumb MP Joint AnatomyThe thumb MP joint allows flexion, extension, abduction, adduction, and a limited range of rotation.Normal Flexion is highly variable from only a 5 degree to over 100 degree flexion extension arc.
3 Indications for Thumb MP Joint Splinting Common injuries of the Thumb MP joint include:Ulnar Collerateral Ligament injuries: Commonly referred to Gameskeeper’s or Skier’s ThumbRadial Collerateral Ligament injuriesDislocations of the MP joint with or without Volar Plate injuryVolar Plate injuriesSesamoid FracturesOsteoarthritis
4 Factors to consider when choosing a splint design Stability of the jointImmobilization of non-involved jointsMaterials used and environmental factorsStability: Complete UCL or RCL tears vs partial tears Healed fractures or VP injuries require less lateral supportImmobilization of non involved joints limits ability to work and play sports.Materials need to be considered if under a glove, to be used in sports, and with skin irritation.

6 Thermoplastic Options Thumb Spica Forearm BasedThumb Spica Hand BasedGalindo-Lim Thumb MP Joint Stabilization SplintUOI Design Thumb MP Lateral Support Splint
7 UOI Design Thumb MP Lateral Support Splint Materials and PatternYou will need:Thermoplastic Material such as NCM Vanilla 3/32 or thin AquaplastKinesiotape, Coban or other adhesive taping.Elastic based Velcro may be used in some casesThe splint pattern as shown
8 UOI Design Thumb MP Lateral Support Splint To make the splint:Make the pattern, place onto material, cut it out and apply it to the patient’s hand.Position the cut out oval over the MP joint. Widen the opening depending on lateral stability required and MP flexion desired.Tag the Proximal Phalanx piece and place thumb in slight opposition with MP positioned in vary degree of flexion depending on goal of splint.
