For Thumb MCP Hyperextension

Use the SIRIS™ Thumb MCP Splint to block hyperextension of a MCP joint. Use on thumbs that can actively abduct; do not use on thumbs that are adducted. A bracelet is available to secure this splint on the thumb. Other options are:

  • To block radial deviation (skiers thumb, game keepers thumb) both Ulnar Lateral Support and Proximal Radial Extension need to be added.  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
