Description

(54) METHOD OF CORRECTION OF VARIAL DEFORMATION OF THE HIP NECK

one

This invention relates to medicine, namely to surgery.

There is a method of correcting the varus deformity of the femoral neck by undergoing osteotomy and correcting the cervical-diaphyseal angle by introducing a distal fragment into the proximal 1.

However, in the implementation of the known method, the formed distal fragment has a small thickness, which leads to fractures. In addition, fixation does not hold the proximal end of the thigh in the position of correction and does not exclude rotational displacement of the fragment. All this reduces the effectiveness and lengthens the duration of treatment.

The purpose of the invention is to safely hold the fragments of the thigh in the correction position.

The goal is achieved by the method of correcting the varus deformity of the femoral neck by subtracting osteotomy and correcting the cervical-diaphysial angle by inserting a distal fragment into the proximal, in the proximal fragment from the side of the greater trochanter, through the cortical layer, form a channel at an angle equal to the angle of correction with the bottom at an angle equal to the osteotomy angle, then the distal fragment is inserted into the formed channel.

FIG. 1-3 depicts a scheme for implementing a method for correcting a varus deformity of the femoral neck.

The method is carried out as follows.

A longitudinal incision of a length of 6 cm Kni, Q ZU from the top of the greater spit expose the femur. Under the periosteum is performed with the help of a Gigli saw, oblique osteotomy of the bone (Figs. 1 and 2) is made at an angle of approximately 30 ° in the direction from the inside to the bottom, up and outwards. The end of the distal fragment 1 is treated with a cylindrical milling cutter (external), and only the irregularities of the cortical layer are removed. Then (Fig. 2) a similar-sized mill (internal) forms channel 2 in the vertical area

2fj of the proximal fragment 3 through the cortical layer at an angle equal to the size of the proposed correction. A grooved bottom 4 of channel 2 forms a grooved chisel, the bevel angle being equal to the angle of the osteotomy of the femur. Sopo

Claims (1)

Claim A method for correcting varus deformity of the femoral neck by means of postoperative osteotomy and correcting the cervical-diaphyseal angle by introducing the distal fragment into the proximal, characterized in that, in order to reliably hold the femoral fragments in the correction position, a channel is formed in the proximal fragment from the side of the greater trochanter through the cortical layer at an angle equal to the angle of correction with the bottom slanted at an angle equal to the angle of the osteotomy, then the distal fragment is introduced into the formed channel.
