Derotation brace for tibia deformities

Claim 1

A derotation leg brace for treatment of internal torsion or external torsion of the tibia bone comprising a rigid strap-type vertical brace bar having upper and lower end portions as well as front and rear sides and adapted to extend along the posterior of the calf portion of the leg of a user, said upper end portion including an integral rearwardly directed angulated strap-type upper terminal end portion adapted to underlie the underside of the thigh portion of said leg with the knee of the user bent to conform to the relative angulation of said brace bar and upper terminal end portion, said upper terminal end portion being joined to said upper end portion by means of a trasversely extending generally quarter cylindrical connecting portion integral with said upper end portion and terminal end portion, projecting outwardly of the opposite sides thereof and adapted to cushion and protect the popliteal fossa of the user, said upper terminal end portion and said upper end portion of said brace bar including transverse integral upwardly and forwardly opening rigid U-shaped leg cradles, respectively, adapted to cradle the thigh and calf portions, respectively, of the user, each of said cradles including adjustable strap means operatively associated therewith for clamping the corresponding leg portion in the ssociated cradle, the lower end portion of said brace bar including a forwardly directed angulated lower terminal end portion, an upwardly opening shoe cradle for cradling the shoe of the user of said brace supported from a forward portion of said lower terminal end portion for adjustable angular displacement of said shoe cradle relative to said lower terminal end portion about an upstanding axis fixed relative to said lower terminal end portion and generally paralleling and spaced forward of said brace bar, said shoe cradle including a lower plate for resting the sole of an associated shoe thereon and means for substantially stationarily anchoring a shoe therein with the sole of the shoe abutted against the lower plate, said upper and lower end portions being slidingly overlappingly engaged with each other for limited guided relative longitudinal extension and retraction, means connected between said upper and lower end portions releasably retaining the latter in infinite relative adjusted positions within the limits thereof, means supporting said lower terminal end portion from said lower end portion of said brace bar for adjustable swinging about a front to rear extending axis spaced above said lower plate and said lower terminal end portion and stationary relative to the latter, means connected between said lower end portion of said brace bar and said lower terminal end portion releasably retaining the latter in adjusted rotated position relative to said lower end portion of said brace bar.
