Thumb MCP Splint with Bracelet, LS & PRX


Block hyperextension and radial deviation of MCP joint.

Online purchasing will be coming soon. For now please download the Order Form and send it via fax or email.


Use the SilverRing™ Thumb MCP Splint with LS & PRX to block hyperextension and radial deviation of a MCP joint. Use on thumbs that can actively abduct and desire more flexion at the MCP; do not use on thumbs that are adducted or have significant CMC problems (see Stable Thumb 3D Splint instead). To block radial deviation (Skier’s thumb, Gamekeeper’s thumb, UCL tear) both Ulnar Lateral Support and Proximal Radial Extension need to be ordered together. When these additions are added the splint will be sent unfinished to verify fit. One remake is allowed at no additional charge. Any further remakes or returns for credit will incur a 25% restocking fee. A Proximal Volar Extension (PVX) can be used to stabilize under the head of the metacarpal joint to reduce more than 15° of hyperextension. The PVX can also be used to secure the splint if it rotates on the thumb while in use. A 25° bend can be added to the proximal ring to further block hyperextension or to promote flexion at the MCP joint.


A bracelet is suggested to secure this splint on the thumb. The bracelet can be wrapped two different ways around the wrist. The bracelet can be criss-cross over itself before connecting back to splint which changes the angle of pull to seat the bracelet better on the wrist and away from the palm. Criss-crossing bracelet can require a longer 9” bracelet which should be requested when ordering. There are 3 clasp options: Lobster clasp, ‘S’ Hook and Magnetic Clasp. The Magnetic clasp has an additional fee and is the best option for people lacking fine motor dexterity or who have difficulty pinching.
