DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a hand and wrist joint orthosis for the treatment of tendovaginitis.
2. Description of the Related Art
From DE-U-17 61 705, a device for the immobilization of the human hand and digits is known, wherein the connection of a splint with a body is effected, whose configuration is such that the hand or the digits to be immobilized in each case are able to rest in a functional position on this body and in that, furthermore, the body is provided with perforations, e.g. slots which, if necessary, permit the attachment of special retaining means, paddings, etc., as well as an air access. According to this, a splint is connected with a body, in which case the splint possesses a configuration and, possessing the form of a dynamic hand splint, maintains the hand in the medical functional position. If the body, which is connected with the splint so as to form a unit, is given the shape of a predeterminable three-dimensional curve whose transversal curve of the hollow hand at the level of the metacarpophalangeal joint and does justice to the convergent course of the digits when the fist is closed and whose longitudinal curve is selected in such a way that the digits bear against the curved hand like tangents, in which case the digits are inevitably moved into the desired articular position, then an immobilization in a functional position can be achieved by a simple bending of the splint. The configuration and size of the body of the splint is chosen in accordance with a mean value of the order of magnitude of the hand(s) of adults as are encountered in nature so that a standard device for providing a hand with a splint that is to fit almost all hands and digits. Occurring minor differences in the size of the different hand are in this connection to be compensated in that the respective hand more or less engages around the surface of the device. However, on account of this it is not possible to support and fixate the metacarpophalangeal joints in the elongated digits at a flexion of from 70.degree. to 80.degree. since no accuracy of fit exists. To this is added the circumstance that the supporting body formed on one end of the splint is constructed in the form of a hollow body so that, when the splint is applied, the elongated digits of the hand grip around this hollow body which possesses an approximately circular cross-section. Because of this a clear angular fixation of the phalanges relative to each other is not ensured. The attachment of the splint on the forearm, wrist joint and digits is effected by the application of a bandage. In order to fixate one or several elongated digits of the hand, a complicated winding and routing of the bandage is called for. That is why the application of this hand splint is possible only through trained specialist staff. If the bandage is not perfectly wound and routed in a pressure-relieving manner when the hand splint is applied and fixated, constrictions and, with this, haemostases, may consequently result. Nor is a stable fixation possible for a prolonged period of time, which is due to the slackening of the tensile forces of the bandage.
DE-U-81 28 832 describes an elastic wrist joint bandage for optional application as elastic support or for the immobilization of the wrist joint; it is designed in such a way that a detachable splint is provided on the inner hand. However, this wrist joint bandage is in no way a dynamic hand splint for supporting the hand in the known medical functional position. The elongated digits of the fixated hand are freely movable when the wrist bandage is applied. The splint extends over a section of the forearm across the wrist joint up to the inner hand and its function is exclusively a supporting one.
From the U.S. Pat. No. 4,584,993, a cuff-like constructed bandage enclosing the carpus and wrist joint without the possibility of maintaining the hand in the medical functional position can be gathered. This wrist joint bandage does in no way make a fixation of the hand in
