To analyze results of surgical treatment of patients with congenital kyphosis in the thoracolumbar spine. Material and Methods. A total of 24 patients aged 3 to 57 years with congenital kyphosis were operated on. Vertebral malformation was detected in 13 patients, malsegmentation-in 4, mixed abnormality-in 1, unclassifiable abnormality-in 3, and congenital vertebral displacement-in 3. Congenital kyphotic deformities were treated using five surgical techniques. Neurological complications were observed in one patient. Results. The average postoperative kyphosis angle was 42° (range: 7° to 68°). The average rate of correction was 34 % (range: 6 to 84 %). Conclusion. Differential use of surgical techniques allows achieving good outcomes of treatment, restoring coronal and sagittal balance, and creating conditions for the proper development of the spine.
A case of surgical treatment of C6 fracture-dislocation and C7 fracture in a patient with ankylosing spondylitis is presented. Two-stage surgery with reposition of fracture-dislocation using the halo apparatus and stabilization with segmental instrumentation was performed. Outcome of the surgical treatment included elimination of deformity, achievement of stable fixation, and reduction of neurological signs observed in the patient before surgery.
The paper presents two cases of surgical treatment for spine deformity and spinal canal stenosis in achondroplastic patients. Both patients underwent two-stage surgery including posterior stabilization of the spine using transpedicular fixation system and anterior spinal decompression. The surgery resulted in deformity correction and achieving stable fixation. At long-term follow-up the improvement of neurologic status, and stable correction and fixation were noted in both patients.
Surgical Treatment of Severe Postlaminectomy Kyphosis S.V. Kolesov, A.N. Prokhorov, M.L. Sazhnev The paper presents a clinical case of severe kyphotic deformity developed in a child after laminectomy and removal of cervicomedular astrocytoma extended from the medulla oblongata to С3 vertebra. The treatment was performed using halo-traction and posterior stabilization of the cervical spine. Key Words: laminectomy, postlaminectomy deformity, spinal cord compression, fixation with metal instrumentation. Hir. Pozvonoc. 2011;(4):35-39.Представлен клинический случай развития тяжелой кифо-тической деформации у ребенка после выполнения лами-нэктомии и удаления цервикомедуллярной астроцитомы на уровне от продолговатого мозга до С 3 позвонка. При ле-чении использовали гало-тракцию и дорсальную стабили-зацию шейного отдела позвоночника. Ключевые слова: ламинэктомия, постламинэктомичес-кая деформация, компрессия спинного мозга, фиксация металлоконструкциями.
Objective: To determine the amount of loss of function after spinal cord transection of varying extents, and whether magnetic iron oxide nanoparticles, in combination with an external magnetic field, improve the rate of subsequent functional recovery in rats. Methods: The animals were divided into groups with 50%, 80% and complete spinal cord transection. The animals of all three study groups were administered magnetic iron oxide nanoparticle suspension to the area of injury. The three control groups were not administered magnetic nanoparticles, but had corresponding transection levels. All animals were exposed to a magnetic field for 4 weeks. Loss of postoperative function and subsequent recovery were assessed using the BBB motor function scale and somatosensory evoked potential monitoring on the first day after surgery, and then weekly. Terminal histological analysis was also conducted in all the groups. Results: The animals in the control or complete transection groups did not demonstrate statistically significant improvement in either the BBB scores or evoked potential amplitude over the four-week period. In the group with 50% transection, however, a statistically significant increase in evoked potential amplitude and BBB scores was observed four weeks after surgery, with the highest increase during the second week of the study. In the group with 80% transection, only improvement in evoked potential amplitude was statistically significant, although less pronounced than in the 50% transection group. Conclusion: The use of magnetic iron oxide nanoparticles in combination with a magnetic field leads to higher rates of functional recovery after spinal cord injury in laboratory animals. The mechanism of this functional improvement needs further investigation.
