[Nonspecific craniovertebral spondylitis]. / Nespetsificheskie spondility kraniovertebral'noi oblasti.

OBJECTIVE: To analyze surgical strategy for nonspecific spondylitis of the craniovertebral region (CVR) taking into account clinical features and morphological signs of disease. MATERIAL AND METHODS: Eight patients with nonspecific spondylitis of CVR underwent surgery (4 women and 4 men aged 31-75 years). Three patients had pain syndrome, 5 ones - conduction disorders. Combined interventions were performed in 5 patients with neurological disorders. Of these, 3 patients underwent transoral decompression with subsequent occipitospondylodesis. In other cases, stages of surgical treatment were reverse. Four patients underwent simultaneous interventions, 1 patient - with 7-day interval. Patients with pain syndrome underwent occipitospondylodesis. RESULTS: In all patients, postoperative VAS score of pain syndrome decreased by 5-7 points (mean 5.5). Among 5 patients with conduction symptoms, regression of neurological disorders 1 year after surgery was achieved in 2 cases, and complete recovery was observed in 3 patients (Frankel E). In all cases, examination confirmed relief of inflammatory process and no compression of the spinal cord and medulla oblongata. One patient had a dehiscence of the wound edges of posterior pharyngeal wall, and another one had implant fracture in 3 years after surgery. CONCLUSION: Active surgical approach is reasonable for nonspecific spondylitis of CVR. Craniocervical fixation eliminates pain and risk of neurological complications following atlantoaxial instability. Conduction disorders require simultaneous transoral decompression and occipitospondylodesis in patients with nonspecific purulent craniovertebral lesions. Impaired head tilt complicates transoral stage. In this regard, it is more rational to carry out craniocervical fixation at the last stage.

[Total resection of aggressive hemangioma of thoracic spine: case report and literature review]. / Total'noe udalenie agressivnoi gemangiomy grudnogo otdela pozvonochnika (klinicheskoe nablyudenie i obzor literatury).

The authors report total resection of aggressive hemangioma of Th7 vertebra in a patient with severe conduction disorders in the lower extremities. Total Th7 spondylectomy (Tomita procedure) was performed. This method provided simultaneous en bloc resection of the vertebra and tumor via the same approach, eliminate spinal cord compression and perform stable circular fusion. Postoperative follow-up period was 6 months. Neurological disorders were evaluated using the Frankel scale, pain syndrome - visual analogue scale, muscle strength - MRC scale. Pain syndrome and motor disorders in the lower extremities regressed in 6 months after surgery. CT confirmed spinal fusion without signs of continued tumor growth. Literature data on surgical treatment of aggressive hemangiomas are reviewed.

[Skip corpectomy in surgical treatment of cervical spondylotic myelopathy]. / Metod «skip corpectomy¼ pri khirurgicheskom lechenii tservikal'noi spondilogennoi mielopatii.

OBJECTIVE: To evaluate the effectiveness and safety of skip corpectomy in surgical treatment of cervical spondylotic myelopathy. MATERIAL AND METHODS: The study included 7 patients with cervical myelopathy following extended cervical spine stenosis. All patients underwent skip corpectomy. Clinical examination included degree of neurological disorders according to the modified scale of the Japanese Orthopedic Association (JOA) with assessment of recovery rate and Nurick score, as well as VAS score of pain syndrome. Verification of diagnosis was based on the data of spondylography, magnetic resonance and computed tomography. The indications for surgical treatment were conduction disorders and their spondylotic genesis confirmed by neuroimaging methods. RESULTS. VAS: Score of pain syndrome decreased by 2-4 points (mean 3.1) in long-term postoperative period. The JOA, Nurick scores and recovery rate (mean 42.5%) demonstrated significant improvement of neurological status in all patients. In all cases, the follow-up examination confirmed adequate decompression and spinal fusion. CONCLUSION: Skip corpectomy provides adequate spinal cord decompression in case of extended cervical spine stenosis and minimizes the risk of complications typical for multilevel corpectomy. Recovery rate indicates the effectiveness of this method in surgical treatment of cervical myelopathy caused by multilevel stenosis. However, further studies on sufficient clinical material are needed.

[En-bloc resection of giant neuroma of thoracic spine via transthoracic extrapleural access: a case report and literature review]. / Blok-rezektsiya gigantskoi nevrinomy grudnogo otdela pozvonochnika s ispol'zovaniem transtorakal'nogo ekstraplevral'nogo dostupa: redkoe klinicheskoe nablyudenie i obzor literatury.

The authors describe surgical treatment of a patient with giant neuroma of thoracic spine. The patient underwent en-bloc resection of tumor via transthoracic extrapleural access. Technical nuances of surgery and operational capabilities of transthoracic extrapleural access for resection of neurogenic tumors of posterior mediastinum are demonstrated. Capabilities of transthoracic extrapleural access are comparable to thoracotomy. The first experience of transthoracic extrapleural access showed its effectiveness in resection of giant neuromas of thoracic spine. Indisputable advantage of this access is less surgical injury compared to thoracotomy. A brief literature review is presented.

[Successful surgical treatment of patient with cervical myelopathy due to ossification of the posterior longitudinal ligament: a rare clinical observation and literature review]. / Uspeshnoe khirurgicheskoe lechenie patsienta s tservikal'noi mielopatiei na fone ossifikatsii zadnei prodol'noi svyazki: redkoe klinicheskoe nablyudenie i obzor literatury.

The authors describe the result of combined surgical treatment of a patient with symptomatic multiple-level cervical spine stenosis following ossification of posterior longitudinal ligament. The first stage included decompressive laminectomy and cervical spine fusion using a screw. At the second stage, CIV-CV-CVI-CVII corporectomy with total resection of the ossified posterior longitudinal ligament and CIII-ThI corporodesis with a bone autograft were carried out. This approach was valuable to minimize the risk of iatrogenic damage to the spinal cord, eliminate long spinal stenosis and perform circular fusion of the cervical spine. These measures led to regression of cervical myelopathy symptoms. A brief review is presented.
