(54) DEVICE FOR TREATMENT OF FEMORAL NECK FRACTURES

(57) The invention relates to medicine, namely to traumatology, relates to devices.

for osteosynthesis of the femoral neck. The purpose of the invention is to increase the stability of osteosynthesis when relying on the Adams arc in persons with osteoporosis, reducing the likelihood of fixer migration. For this, a three-blade, non-canal nail has an arcuate shape with grooves along the edges of the blades at the base, which allows it to be inserted under the large trochanter, supported by the Adams arc with an almost vertical position of its end in the central fragment, passing at the center of the femoral head in direct projection . 4 il.

The invention relates to the field of medicine, and specifically to traumatology.

The purpose of the invention is to provide stable osteosynthesis while relying on the Adams arc in persons with osteoporosis.

FIG. 1 shows a device for osteosynthesis of the femoral neck, general view; in fig. 2 - the same in the working position; in fig. 3 is a section A-A in FIG. one; in fig. 4 is a section BB in FIG. one.

A device for treating femoral neck fractures is made in the form of a rod 1 curved along an arc of circumference with longitudinal lobes 2 having transverse slots 3.

After reposition of the fragments of the femoral jaw and fixation of the patient on the operating table, we insert an injection needle along the front surface of the femur 2 cm below the chupper band and 1.5: -2 cm outwards from the femoral artery through soft tissues to the bone and the tip of the needle we feel the lower surface femoral neck. We carry out a hip x-ray in two projections. With satisfactory reposition of fragments, we make a longitudinal reserve of soft tissues under a large spit 4–5 cm long, perforate the cortical layer of the femur. Through a hole in the bone to a depth of 2-3 cm we introduce the device with the help of Petrov-Yasnova guide, which has a curved pointer corresponding to the curvature of the nail.

The paramount is fixed by hand in position so that the needle is 1 cm proximal to the reference injection needle. The angle of the device in the side. projection determined by the method of Petrov-Yasnova. We carry out a control radiography of the hip joint in two projections. If necessary, we correct the direction of insertion of the device. When knocking in, we direct it to

Adams arc. Due to its arcuate shape, it slides over it, necessarily extends in a forward projection at the level of the center of the femoral head and is located in the central fragment, more vertically than the axis

femoral neck. Application of the slot 2 on the blade x 2, the arcuate shape of the rod 1 and, as a result, the almost horizontal insertion into the peripheral fragments prevents its migration. The wound is stitched.
