(54) METHOD FOR RECONSTRUCTION OF THE ROOF

BOTTOMS

This invention relates to medica, namely surgery. A known method of reconstruction of the acetabular roof by dissecting the ilium and implanting the graft into the graft. However, the known method does not allow creating a reliable support for the femoral head and preventing the graft resorption. The purpose of the invention is to provide a firm support for the femoral head and to prevent the resorption of the graft. This aim is achieved in that the reconstruction method roof vertpuzh hydrochloric depression effected by incision of the ilium and embedding in splitting graft manufac t double osteotomy ilium in mutually perpendicular planes more bent the formed kortikal but-sponge tshastinki with periosteum and attached yugtsimis muscles before contact of their peripheral areas and then inject two allografts perpendicular to each other in the cleft. FIG. 1 shows the hip joint with an incomplete nadvertous bone osteotomy; in fig. 2, the plate is bent over the head of the thigh together with the limbus and the attached portion of the rectus femoris muscle; in fig. 3 - hip joint with a formed roof, side view; On fng, 4 - the same, front view. The method is carried out as follows. In the interval, the muscles of the middle annual and fascia fasciaeus are carried out to the roof of the vertebral vial. Spreading the xyths, using a grooved chisel, at the ngocny edge of the attachment to the pelvic bone of the small annual muscle, dissect the outer cortical plate and, directing the blade of the bit downwards and inwards, dissect the spongy substance kps1i.

Attaching a portion of the rectus femoris muscle to the edge of the heliport, after which the chisel is directed perpendicularly to the body of the iliac bone and the osteotomy of the perimeter region 1 is performed.

Simultaneously, the split part 2 of the bone is tilted along with a portion of the rectus femoris, the limbus and the capsule (Fig. 2).

Then, with a flat chisel, cut the longitudinal base 3 of the Ilium (figure 2) front to back and fold the lower edge of the cortical-spongy plate 4 together with the periosteum and the attached part of the small annual muscle 5 (figure 3).

In the first splash formed, the allograft is 6 cm in size from the bones of the cranial vault (Fig. 24). Bent plate overlap the head of the thigh.

In the second cleft, a trapezoidal graft 7 (Fig 3 and 4) is inserted using a hammer blow. In this case, both grafts, perpendicular to each other, are in close contact with each other. Bent plates overlap allografts from the bottom and the outside.

The introduction of two allografts in the ileal cleft in mutually perpendicular p1l, 1x planes provides rigidity for their fixation.

The proposed method for reconstruction of the acetabular roof provides stimulation of formation during dystrophic processes in the acetabular roof.

Due to the environment of the grafts bent cortical-spongy

the plates of the mother bone with the periosteum and the attached muscles create good conditions for their vascularization, and therefore, consolidation with the mother bed in the shortest possible time, followed by uniform restructuring and replacement.

The tight fit of the grafts to the spongy surface of the bed of the recipient over a large area creates optimal conditions for their organotopic reorganization without loss of bone substance.

The proposed method is simple and ensures the creation of a good arch of the acetabulum.
