This invention relates to medicine, namely to traumatology and orthopedics.

The purpose of the invention is the restoration of rotational movements of the thigh.

The method is carried out as follows.

General methods access the prosthetic hip and endoprosthesis from the medullary canal. The pelvic part of the endoprosthesis was not affected. Autografts in the form of a paling fence were inserted into the bone marrow canal around the leg of the endoprosthesis. Subsequently, the leg prosthesis is firmly embedded in the bone-marrow channel of the femur. Big spit with help

renna joint. Expose.proximal-iQ with the screw tip is fixed to the endpro

ny. division of the femur, cut off the big skews, retracted proximally. At the base of the cervical stem of the endoprosthesis, 1.5-2 cm from the edge of its opila, transverse osteotomy of the femur is performed, the stem of the endoprosthesis is partially removed from the medullary canal of the femur, not the pelvic component of the endoprosthesis. Around the leg of the endoprosthesis, in its upper part, in the form of a paling, cortical-spongy autotransplant is poured out with the spongy part outwardly, the leg with the transplants is inserted into the bone-marrow channel of the femur and the greater skewer is fixed.

Example. Sick V., 49 years old, case history No. 26115. Was admitted to the clinic 3 months after the initial hip joint arthroplasty due to joint pain and loss of limb support.

Passive movements in the joint were preserved, rotational - absent

whether. Radiographically, a complete dislocation of the keys of the endoprosthesis, nonunion and migration of the greater trochanter, osteoporosis around the endoprosthesis weave, a positive symptom of endoprosthesis play, were noted.

A repeated operation was performed on the hip joint: an osteotomy on the 1.5 cm of the femur under the scle en. doprosthesis, leg partially extracted

The iQ of the screw is fixed to the endoprosthesis pc. The wound is sutured in layers tightly.

The patient was examined after 3 g: no complaints, the function of the limb was restored, the radiopathic position 15 of the endoprosthesis was stable, the loosening was not revealed.

Using the proposed method allows to significantly reduce

the invasiveness of the operation due to maniulation only with the femoral component of the endoprosthesis, to ensure that the leg of the endoprosthesis is firmly fixed in the bone marrow canape of the femur. In addition, it makes it possible to avoid replacing the endoprosthesis, and, ultimately, restore the function of the operated limb.

Invention Formula g A method of treating hip joint instability, exposing the proximal femur, cutting off the greater trochanter and subsequent fixation, inserting the endoprosthesis leg into the bone marrow channel, characterized in that, in order to restore rotational movements of the thigh, at the base of the endoprosthesis neck transverse osteotomy with removal of the osteoporosis zone, cortical-spongy autografts with the spongy part outwards are placed around the leg of the endoprosthesis.
