Hyperextension of the middle joint of the thumb beyond a neutral position may result in a painful and unstable joint, decreased power, and difficulty in grasping large objects. Without stabilizing or the hyperextension, the joint can become dislocated.
Arthrography of the thumb metacarpal phalangeal joint is useful in defining the anatomy of ulnar collateral ligament ruptures. When the proximal end of the ligament is turned back, operative treatment is indicated. Approximately 1/4 to 1/2 cc of contrast is instilled into the joint and ...
The full range of motion for the thumb MCP joint is about 60° which is almost completely flexion. The movements in this axis are limited by ligamentous structures that surround the joint and antagonistic muscles. Abduction and adduction The full range of motion in this axis is around 25-30...

of the nature of the soft tissue anatomy that defines the paths of the intrinsic muscles of the hand inserting into the extensor hood (also known as the dorsal expansion), this assumption may not be true for the intrinsic muscle moment arms at the Proximal Interphalangeal (PIP) Joint. These...
We described a splint that was successfully used in the conservative management of a grade II thumb MCP radial collateral ligament sprain. Its features provide for MCP immobilization while maintaining IP and CMC joint motion, with minimal loss of function. This splint may be used after thumb ...

Use the SilverRing™ 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 or have significant CMC problems (see Stable Thumb Splint with PVX instead). A Proximal Volar Extension (PVX) is used to stabilize...
