Description

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

Known methods for performing osteosynthesis of the proximal end of the humerus using knitting needles. They have inherent disadvantages: the possibility of inflammatory complications in the area of the passage of the spokes and rods, which complicates the rehabilitation of postoperative treatment and lengthens its duration, as well as the need for external fixation of the spokes in the ring of the Ilizarov apparatus. The presence of a cumbersome external structure complicates the postoperative social adaptation of patients.

A method is known for surgical fixation in a fracture of a surgical neck of the humerus (A.P. Barabash, L.N. Solomin. Combined intense osteosynthesis. - Blagoveshchensk, 1992, p. 45-48), by which the fracture is also fixed intramedullary with a spoke, proximal end which has a persistent pad. The distal end of the spokes is fixed in the lower third of the shoulder in the ring of the Ilizarov apparatus. This method is accepted by us as a prototype. The disadvantages of the prototype described above, since the fixation is achieved using an external device.

The aim of the invention is the development of a method for fixing a fracture of the surgical neck of the humerus is quite simple and provides stable osteosynthesis with the exception of the disadvantages of the prototype.

The goal is achieved in that through the fracture line of the surgical neck of the humerus in mutually perpendicular planes two specially curved hairpins are intramedullary, which ensures sufficient fixation strength with the exception of hairpin migration.

The invention solves the medical and technical task of reducing treatment time and eliminating inflammatory complications that depend on the presence of an input “gate” for infection according to the prototype in that two hairpins are inserted intramedullary through the fracture line of the surgical neck of the humerus in mutually perpendicular planes, said hairpins being made of knitting needles for traumatology by bending them in the form of a "figure eight" with one end open, which remains in the form of a fork and pointed ends. The other closed end of the hairpin - ″ eight "is called the base.

Figures 1 and 2 show a method for introducing hairpins in direct and axial projections, where 1 is the proximal humerus, 2 is the fracture line, 3 is the hairpin, 4 is the hairpin base, 5 is the cortical layer, 6 is the perforation of the cortical layer .

The method is as follows.

Through the perforations of the cortical layer 6 and through the line of fracture 2, two studs are intramedullary. The studs are mutually perpendicular in the sagittal and frontal planes, and before the operation, these studs are bent from the needles for traumatology in the form of a "figure eight" with one end open, which remains in the form of a fork with pointed ends. Due to the original bending of the base of the hairpin, the latter is blocked in the perforations of the cortical layer, which prevents the migration of the latter in the distal and proximal directions.

Clinical examples.

Patient Sh., Born in 1949, was hospitalized on the second day after an injury with a fracture of the surgical neck of the left humerus with displacement of fragments. Closed reposition of the fracture and osteosynthesis with two strained studs were performed. The day after the operation, active therapeutic physical training was started with movements in the shoulder joint; additional external immobilization after the operation was not carried out. On the 12th day after hospitalization, the patient was discharged for outpatient treatment with the possibility of self-care of a damaged limb. Five weeks after the operation, control radiography revealed a fusion of the fracture with full joint function.

The proposed method allowed to solve the following medical and technical problems:

reduction of treatment time, due to an increase in fixation strength, during osteosynthesis due to two mutually perpendicular hairpins without the use of external fixation means;

there are no cases of hairpin migration due to a special way of bending the base of the latter and blocking in the perforation hole of the cortical layer of the humerus.

Statistical processing of the proposed method and the method selected as a prototype are given in table. 1 and 2.
