RU57107U1 - EXTERNAL FIXATION DEVICE FOR TREATMENT OF DAMAGES AND DISEASES OF THE CERVICAL SPINE WITH AN EXTRA BASIC SUPPORT - Google Patents

Abstract

The utility model relates to devices used in medicine, namely in neurosurgery and traumatology. The technical result of the proposed device is a more reliable fixation and correction of the cervical spine due to the proposed basic support with transosseous fixation with knitting needles held through the acromial ends of the clavicles and acromial processes of the shoulder blades, mounted in the spokes installed in the half rings of the Ilizarov apparatus and interconnected by beams through the straps and telescopic rods. The proposed apparatus consists of a Halo-ring, a fastener, and a base support with transosseous fixation with knitting needles drawn through the acromial ends of the clavicles and acromial processes of the shoulder blades attached to the spokes installed in the semicircles of the Ilizarov apparatus and interconnected by beams through trims and telescopic rods. The effectiveness of the proposed device is more reliable fixation and correction of the cervical spine.

Description

The utility model relates to devices used in medicine, namely in neurosurgery and traumatology.

According to the literature, Halo devices of various designs are known to be used to treat injuries and diseases of the cervical spine and Ilizarov apparatus used to treat injuries and diseases of the musculoskeletal system.

Known Halo devices of the company Medbiotech and CITO, which allow for the correction and stabilization of the cervical spine in case of damage and diseases. (Babkin A.V., Makarevich S.V., Mazurenko A.N. All-Russian Scientific and Practical Conference. Abstracts - Novosibirsk. 1996, p. 19; Vetrile S.T., Kolesov S.V. Congress Materials orthopedic traumatologists of Russia with international participation “New implants and technologies in traumatology and orthopedics.” Yaroslavl. 1999.

For the prototype, we selected a device for external correction and fixation of the cervical spine (Halo apparatus) "Medbiotech",

described in the abstract of A. Babkin "Diagnosis and treatment of upper cervical vertebrae." Minsk. 1997 Fig. 1, photo 1, 2., where 1 - Halo-ring, 2 - attachment point, 3 - corset.

The technical result of the proposed device is a more reliable fixation and correction of the cervical spine due to the proposed basic support with transosseous fixation with knitting needles held through the acromial ends of the clavicles and acromial processes of the shoulder blades, mounted in the spokes installed in the half rings of the Ilizarov apparatus and interconnected by beams through the straps and telescopic rods. Our external fixation apparatus for the treatment of injuries and diseases of the cervical spine with transosseous support (Halo-apparatus SMaN) (Fig. 2) consists of 1 - Halo-ring, 2 - spoke, 3 - spoke, 4 - half rings of Ilizarov apparatus, 5 - beam, 6 - level, 7 - telescopic rods, 8 - basic support.

The essence of the proposed method.

In the position of the patient “on the back” or “sitting”, depending on the severity of the patient’s condition, a Halo-ring of the Medbiotech apparatus or a ring of the Ilizarov apparatus with a diameter of 225 mm is installed under local anesthesia. Under local anesthesia, through the acromial ends of the clavicles and the acromial ends of the shoulder blades in the frontal plane, two spokes are mutually crossed at an angle of 30 degrees with solders, which are fixed in the spokes installed in the half rings of the Ilizarov apparatus. The half rings are interconnected by beams through short trims. Halo-ring and transosseous basic support are interconnected by four telescopic rods mounted symmetrically around the perimeter.

X-ray control and correction of the displacement of the vertebrae is carried out by changing the length of the telescopic rods.

The effectiveness of the use of SMaN apparatus is more reliable fixation and correction of the cervical spine.

Clinical example.

Patient S. Injury 1.5 months before hospitalization - fell on his head when exiting the bus. Treated for concussion. After 1.5 months, he was hospitalized again due to increasing tetraparesis, impaired coordination, dysphonia. Examination revealed a fracture of the Shtip atlant according to Landells. Diagnosed with a fracture of type III Atlant Landells with compression of the spinal cord, tetraparesis Fr D, dysphonia. On spondylograms: the lateral masses of the atlas are shifted outwardly by 3-5 mm from two sides. Hallo-apparatus with transosseous base support was applied to the patient, moderate distraction was performed. Drug therapy was performed. Tetraparesis regressed after 7 days, after 12 days dysphonia and impaired coordination regressed. After 35 days, the Hallo-apparatus with the transosseous base support was dismantled, and fixation with a rigid head holder continued. On the control spondylograms: on the right is the correspondence of the articular surface C1-C2, on the left is the displacement of the articular site C1 outward by about 0.3 cm.

Claims (1)

External fixation and correction device for the treatment of injuries and diseases of the cervical spine with transosseous base support, including a Halo ring and an attachment point, characterized in that for fixing the Halo ring and attachment point, a base support is used with transosseous fixation with knitting needles drawn through acromial ends clavicles and acromial processes of the shoulder blades and reinforced in the spokes installed in the half rings of the Ilizarov apparatus and interconnected by beams through the slats and telescopic rods.
