Abstract: A finger and hand brace includes an elongated brace body applied lengthwise to the wrist and finger regions of the hand, with multiple straps extending from the brace body. The straps have sufficient length to wrap about at least two of the hand, wrist, a finger or fingers. Hook-and-loop fasteners on the brace body retain the straps in a wrapped condition. At least two elongated stiffeners are carried by the brace body inside pockets. A separation line, located at about the wrist, extends laterally across the brace body and enables the brace body to be separated into a distal/finger portion discrete from a proximal/wrist portion. The stiffeners and pockets are likewise separable into distal and proximal portions. The distal portion of the brace body includes a flap that holds the distal portion to the proximal portion of the brace body.

A protrusion provided to the interior of the outer sleeve interacts with a groove and recesses, corresponding to desired height settings, configured in the inner leg. A biasing member provided to the adjustable leg acts against a surface of the inner leg while mounted to the outer sleeve, urging the inner leg against the protrusion and facilitating easy engagement with the recesses.
