A recent study diagnosis include meniscal cysts, congenital subluxation of showed an even stronger association betweed a discoid the knee, congenital cruciate ligament aplasia, the snap- meniscus and osteochondritis dissecans of the lateral ping of tendons and dislocation of the patella. Treatment Pathogenesis While discoid menisci cause no, or just a few, symptoms, It was initially assumed that the disc shape developed as there is no need for surgical treatment. If frequent, un- a result of incomplete breakdown of the central section of pleasant snapping occurs, however, arthroscopy and pos- the meniscus. However, embryological studies have shown sible treatment are indicated. Many authors continue to that the lateral meniscus does not show a discoid appear- recommend a complete lateral meniscectomy, and good ance at any phase of fetal development. For this reason (particularly for the com- the joint space has formed, the central mesenchymal mass plete and incomplete types), only the central section of has disappeared and mesenchymal tissue is only present the meniscus should be removed. This procedure should, at the edges, where the cartilage subsequently differenti- if possible, be performed by arthroscopy and is technically ates to form the menisci. In discoid meniscus, therefore, more difficult than a resection for a flap or bucket-handle fibrocartilage must develop from mesenchymal tissue at a tear. The treatment of the hypermobile Wrisberg type, site where this does not normally occur. In these cases the normal anchorage of the lateral posterior horn, although we do not have extensive lateral menisci on the tibial condyle is lacking, and the experience with this procedure and we are unaware of meniscus is only secured to the lateral meniscofemoral corresponding reports in the literature. Such menisci are hypermobile and become hypertrophied as a result of mechanical loading.

For this reason, braces are particularly ef- ficient if they are worn throughout the day as functional 4 4. This important active element is missing in relation > Definition to nocturnal splints. Although they retain the secured Orthoses are supports applied externally to correct body sections in an ideal position at night, functional a deformity or to control the forces acting on the control is not ensured during the day.

Although the patients may while at the same time correcting abnormal function tolerate such unpleasant sensations during the day while and/or shape. Orthoses can only act from the segment that is stable in Consequently, patients will often minimize any stretching space on the more unstable segment. For example, the or even dispense with the use of the orthosis altogether, stable ground can be utilized to shape the overlying foot making the nocturnal splint completely ineffective. The these reasons we prescribe nocturnal splints only in rare appliance in this case is known as a shoe insert and acts individual cases. During the swing phase, by contrast, deformities interfere with function, functional the foot must be held by the lower leg (ankle-foot ortho- orthoses are more useful than splints. A distinction must Orthoses should correct the shape of, and stabilize, the therefore be made between stance-phase and swing-phase bridged body sections. If the orthosis is in the anatomically correct position they are loaded in cut away at these pressure points, this allows further the optimal manner, for example as in a normally shaped deformation to develop. Only in this way can the foot remain a stable lever of the pressure points, while the deformity becomes arm for the triceps surae muscle, which is a key muscle for increasingly accentuated to the point where the orthosis posture control. The correct procedure in the foot is adequate muscle activity and dynamic control the event of pressure points is to check the position of during weight bearing. Only then can disruptive external the body section in the orthosis and, if necessary, order forces be intercepted. Since this dynamic control is usually a new orthosis in the correct position rather than make lost in neuromuscular disorders, progressive deformities further adaptations. Consequently, inappropriate muscle stabilization but are usually due to incorrect or incomplete occasionally leads to severe deformities such as flat feet correction of the embedded body segments.

Modern technology and the use of plastics are therefore preferable to the old designs made from metal and leather [1, 3]. In addition, leather is not washable and therefore hygienically suspect, particularly for those parts of the body where profuse sweating occurs (feet, hands and trunk). Shoe insert and shoe modifications > Definition Inserts can be incorporated in the shoe loosely or as fixed components. They support the calcaneus by the ap- plication of pressure from below and straighten the foot deformity. The footwear may need to be strengthened in order to keep the foot positioned over the insert. For foot deformities such as pes planovalgus, it serves as a tried-and-tested resource as long as powerful ⊡ Fig. The aim The heel is balanced, and the whole foot thus indirectly straightened, of the insert is to correct the shape of the foot by applying via the medial and lateral support, which must be located under the counterpressure to the foot.

In all cases, the patient must at least understand the longus muscles (Operation according to Green). These extensive conditions are rarely fulfilled clude any functional deterioration resulting from a loss in patients with spastic tetraparesis since they are almost of power of the transferred muscle. A wrist arthrodesis invariably retarded to a greater or lesser extent, difficult can also produce a functional improvement by providing to motivate and unable to provide sufficient cooperation.
