For General IP Instability

SilverRing™ Spiral Splint on the Thumb IP joint

Use the SilverRing™ Spiral Splint to treat hyperextension and very mild lateral instability of the IP joint of the thumb. This splint allows full flexion and can be adjusted for enlarged joints. The spirals can be loosened or tightened, they can be spread apart or compressed to change the length, and the entire splint can be bent to adjust the angle at which the joint is held. Since this splint blocks hyperextension and helps with instability, prehension is more powerful and less painful.  This splint will not be as strong as a Swan Neck Splint or Boutonniere Splint when blocking hyperextension and therefore can more easily be overpowered.
