Principle of the Luque- 3 Galveston technique in severe scoliosis and spastic tetraparesis. On the con- cave side of the curve a rod is anchored in the pelvis in an orthograde position as possible. The spine is then seg- mentally pulled onto the rod, thereby correcting not only the scoliosis but also the pelvic obliquity. A second rod anchored in the pelvis on the convex side and fitted with segmental wires ensures adequate stability ⊡ Fig. In our is only instrumented in the low thoracic area, a new ky- case we use the titanium pediatric USS instrumentation, phosis will develop above the instrumentation as a result as the screws and rods are rather smaller than usual and of kyphosing forces acting at this point. It is important that the kyphosis should be nial and caudal ends right up to the turning point of corrected over a prolonged section.

The »Little People« (who appear all too rarely alas) are particularly considerate 25mg fildena fast delivery erectile dysfunction at age 64, helpful and kind creatures cheap fildena 50 mg overnight delivery erectile dysfunction hand pump, while gnomes decorate the gardens of many homes as bringers of good luck. Even though society may ascribe certain positive qualities to dwarfs there is no doubt that small stature is Rumpelstiltskin associated with considerable psychological problems for those affected. If we were all small then small people would not have any particular problems. In a study of young people aged between 14 and 20 with heights between 85 cm (2 ft 9 in) and 150 cm (4 ft 11), 85% did not consider themselves to be disabled. Very small individuals experience restrictions in their every- day lives because they are unable to reach light switches, elevator buttons, washbasins or shop counters, but these functional handicaps can at least be minimized by practi- cal appliances and a certain amount of creativity. Of much greater consequence and far more difficult to cope with is the »social handicap«: the stigmatization based solely on a difference in height. The fact that other people turn round and stare, almost as a reflex action, simply because one is particularly short. The fact that small individuals automatically become the center of at- tention whenever they venture into the outside world: on Dwarf Long-Nose the street, in restaurants, on public transport, everywhere. The reactions they encounter range from astonishment, insecure or very unusual behavior, sympathy, mockery extending to maliciousness, depending on the maturity of the onlooker. Height therefore appears to play an extremely impor- tant role in our society. A study by an anthropologist investigating the connection between shortness and tall- ness with properties that are attributed to them showed that a tall person was considered to be healthier, stron- ger, more interesting, more serious, more active, safer, tougher and more open than a short person. This range of properties is also commonly ascribed to suc- cessful individuals. In this context, the wish of many small people to be made taller with the help of advances in modern medicine is perfectly understandable. Many are prepared to invest a great deal of time and effort and Quasimodo tolerate considerable pain in order to achieve their goal. Associations of little people resolving the problem than a distressing bilateral leg exist in many countries of the world.
