Abstract
An adjustable spring-loaded splint device is provided for supporting the ankle joint of a wearer. The splint device includes a pair of spaced lower struts and a pair of spaced upper struts pivotally connected to lower struts. The lower struts each include, at one end, a pivotably mounted head portion defining a cam surface, and the upper struts each include an adjustable spring assembly mounted therein, including a spring biased into engagement with the cam surface, for applying a quantifiable force tending to align the upper and lower struts. Upper and lower sets of cuff and strap members are connected between the upper struts which adjustably and releasably secure the splint device to the limb of the wearer using a detachable fastener including hooks and loops fastener sections. An adjustable footplate assembly is pivotably connected to the lower struts of the splint device for securely supporting the foot of the wearer in a selected relation with respect to the ankle. An elevating sole, which is of variable thickness and is adapted to be secured to footplate assembly, can be used in supporting the foot at a given height above the ground.
