DESCRIPTION:
BRIEF SUMMARY
The invention relates to an orthopedic brace for splinting and for balancing the lateral instability of knee joints.
Orthopedic braces of this nature comprise an upper and a lower splint elements of rigid material flanking the upper and lower parts of human legs to a greater or lesser extent, the two splint elements being interconnected by means of a hinge-like joint. It is disadvantageous that an orthopedic brace of this nature does not allow of the natural combined rolling and sliding action of the physiological sequence of motion during the bending and straightening of the human knee, which leads to an unnatural and deleterious strain on the joint-forming bone surfaces of the thigh and lower thigh bones, and causes the onset of muscular atrophy in the upper and lower parts of the leg. This is a consequence of the lateral rigidity of the orthopedic brace. Furthermore, the knee movement imposed on the knee by this already known orthopedic brace results in the disadvantage that the patient finds it unpleasant to wear the orthopedic brace, in particular also because of the lateral rigidity of the orthopedic brace.
The object of the invention consists in devising an orthopedic brace of the kind defined in the foregoing, which allows of the lateral sequence of motion of the knee and is pleasant to wear.
The solution to this problem is based on the orthopedic brace specified and is characterised by a tie-plate intended to be applied on the knee joint side having the preponderant instability and acted upon by elastic belt straps which lead to fastening points situated offset above and below as well as laterally with respect to the tie-plate, the lines of action of two mutually adjacent belt straps in each case intersecting each other in the region of the tie-plate.
Thanks to this solution, the natural sequence of motion of the joint-forming bone surfaces of the thigh and lower thigh bones is assured under satisfactory balancing of the lateral instability of the knee joint, since no movement of any kind is imposed on the knee joint by the orthopedic brace. The muscular atrophy referred to is averted thereby.
Furthermore, the orthopedic brace according to the invention is pleasant to wear, since the tie-plate and the straps acting on the same may yield to the individual movements of all the knee elements playing a part in the movement of the knee in its area, without causing unpleasant feelings of pressure or the like. The patient's willingness to wear the orthopedic brace readily is also promoted thereby, which for its part is beneficial to the curative intent.
The invention is described in the following in respect of an example of embodiment illustrated in the accompanying drawings. In these :
FIG. 1 shows the example of embodiment in a first sideview,
FIG. 2 shows another sideview of the example of embodiment corresponding to the arrow A in FIG. 1.
According to the figures, the orthopedic brace illustrated, which is to be worn by the patient in the region of the knee, for example after plastic knee ligament replacement, comprises a tie-plate 1, an upper shackle 2, a lower shackle 3 and several elastic belt straps 4,5,6 and 7. The belt straps act on the tie-plate 1 on the one hand, and are secured on the other hand to fastening points of the two shackles 2,3, e.g. by means of rivets 8, these points being situated on the shackles offset sideways with respect to the tie-plate, as clearly apparent from FIG. 1. The attachment of the belt straps on the tie-plate may be released and may for example be performed in such manner that splice straps 9,10 are provided with loops 11,12, the belt straps being passed through the loops as illustrated. Two of the splice straps 9 and 10 in each case are fastened to the tie-plate 1, e.g. by means of a rivet 13. Furthermore, the belt straps extend from the shackles 2,3 in the direction towards the tie-plate, in such manner that the lines of action of two mutually adjacent belt straps in each case intersect each other in the region of the tie-plate, as clearly apparent from FIG. 1.
