The CaligaLoc anatomically contoured stabilizing orthosis is used as a conservative treatment for torn ankle ligaments, after operations on the ligaments or in cases of chronic instability of the upper and/or lower ankle. It offers round-the-clock protection against unexpected or excessive strain and prevents the ankle from twisting outwards. CaligaLoc can be worn as a support splint in normal shoes, but also without shoes as a postural or night-time support. Flat micro-Velcro fastenings are used to adjust the level of support. The stability element can be reshaped thermoplastically if the individual anatomy of the foot requires this. Partial immobilization with CaligaLoc thus guarantees optimum wearing comfort until a greater degree of mobility is possible.
