SU624610A1 - Method of intraarcticular prosthetics of head and neck of the femur - Google Patents

Description

The invention relates to the field of medicine, namely to traumatology, and concerns a method of intra-articular hip joint prosthetics using endoprostheses.

There is a method of intra-articular prosthesis of the head and neck of the femur by a T-shaped incision of the hip joint capsule, resection of the head and partially. femoral neck.

However, this method does not provide high reliability of attachment of the endoprosthesis.

The aim of the invention is to increase the reliability of the endoprosthesis.

This is achieved by making a slot a width equal to the diameter of the endoprosthesis neck on the upper surface of the femoral neck, and through the slot into the femur

The method is carried out as follows.

Access to the joint is made through a Smith-Peterson incision. T-shaped cut through the capususustava. WITH

Claims (1)

using bits, the loose head is removed (for subcapital fractures, false joints). Through external rotation of the thigh, the proximal end of the femur is removed into the wounds. On the upper surface of the neck make a slot up to 18 mm wide full length to the skewer. A bed for an endoprosthesis is prepared with chisels and a bone spoon. The leg of the endoprosthesis is inserted into the bone marrow canal, and the cervical part of the endoprosthesis is inserted into the bed prepared in the neck. In the neck, the endoprosthesis rests on a dense bone that has retained a connection with soft tissues, and it can be expected that tissue will grow into the neck slot, rich in blood vessels, which is important for the cervical stump. The end of the neck with bits and cutters is processed according to the shape adjacent to the neck of the endoprosthesis head. The capsule and the wound are sutured in layers and silk sutures are applied to the skin. Aseptic dressing is applied, rest, movement in the joint is carried out on a special functional tire. The movements in the operated joint begin on the first day after surgery on the functional tire (flexion, extension every 6-8 hours). Gypsum immobilization is completely excluded. For 2-3 days, patients can sit in bed. The proposed method of endoprosthesis makes it possible to improve the conditions of fixation of the endoprotea to the bone with maximum preservation of the femoral neck and to increase the reliability of the attachment of the endoprosthesis. The load experienced by the prosthesis is distributed over a larger area of bone than with other methods of prosthesis. In addition to maximally preserving the cervix, the conditions for fixing the cervix of the endoprosthesis are improved; a significant part of the greater trochanter is not removed. The proposed method of endoprosthesis may not be used for subcapital fractures, non-adult medial fractures, false joints, pathological processes in the head, with B1, surgical intervention possible and with a shortened neck. Claims method of intra-articular prosthesis of the femoral head and neck by means of a T-shaped incision of the hip joint capsule, resection of the head and partially the femoral neck, characterized in that, in order to increase the reliability of the endoprosthesis attachment, a slot is made in the upper surface of the femoral neck throughout its length equal to the diameter of the endoprosthesis neck and through the slot, an endoprosthesis is inserted into the femur.
