Abstract: It is possible to satisfy all the requirements of minimal invasivnes with maximal permanent result by placing the invented implants (screw). The shape of the screw solves all mentioned technical problems that occurred thus far, i.e. it can be directed through a small gap in the skin by Kirschner's guide-wire (because the screw is hollow- canulated). The screw is larger in body, so a much greater force is needed for it to break. If it does break, it can be removed easier with less lesions to the surrounding bone tissue. At the point of the screw are trisect cuts (on the apex thread) which also make the lesion of the bone lesser as it is inserted in its position. Since the head of the screw is bigger and conical, without a narrow part leading to the screw-thread, the screw self-tightens into the bone, which makes the loosening rarer. The loosening is also rarer because of the shape of the screw-thread. The screw has the equal effect throughout the whole time it is implanted in the body. The osteolysis of the heel bone in which the screw stems against is also reduced. The conical shape of the head of the screw, without a narrow part (neck) between the head and the screw-thread, it does not allow ingrowing of the bone tissue, so it can be easily removed when the necessary time of correction is finished. The time necessary for the surgical procedure is significantly shorter, taking up 15 minutes, thus reducing the possibility of a infection, which is also helped by a small operative area. After the placement of the screw, the patient can walk two days after the surgery and he/she does not need any plaster immobilization or physical therapy. The screw is made out of titanium alloy, which gives it a certain toughness; the patient can undergo magnetic examinations, if there is need for such, while the screw is implanted.

Abstract: The canulated titanium implant (screw) for correction of flat feet in children characterized by that: a) the diameter of the stem is D=4,8mm±25%, recommended 4,8mm±10%, and especially recommended 4,8mm, b) it is canulated, whose diameter is C=2mm+25%, recommended 2mm±10%, and especially recommended 2mm, c) the screw-thread height is l,15mm±25%, recommended l/15mm±10%, and especially recommended 1,15mm, d) on the point of the screw, which ends at the angle of 90°, on the apex thread are trisect cuts at the angle of 120°. The edges of the apex thread are cut at the angle of 55°. At the very top of the point of the screw, the trisect cuts of the apex thread go inward the tunnel in the length of the screw by 1,5mm, e) this type of the point replaces the use of the drill and the tapping device.
