The periodic failure of pedicle screw insertion and anatomical variations make the search for an alternative to pedicle screws in thoracic spine surgery necessary. The interlaminar crossed screws is a well-known and secure method for fusion in cervical spine, and in thoracic spine there used to be insufficient clinical data to support this technique, until now. We demonstrate in an initial series of 10 cases treated with interlaminar fusion in association of other fusion techniques in the thoracic spine with good results. Objective: Intralaminar screws have been shown to be a biomechanical salvage technique in the thoracic spine, especially in long cervicothoracic, thoracic and thoracolumbar fixation. The goals of this article are to demonstrate our initial experience and the range of indications for thoracic crossed intralaminar screws. Methods: In this article we describe our initial series performed at São Teotónio Hospital in Viseu, Portugal, and our results, and also provide a comprehensive review of the recent literature in the use of intralaminar crossed fixation.展开更多

Methods We took respective analysis on diagnosis, treatment and recovery results of 12 cases, whose symptoms, signs and MR were explicit. Results Follow ups times were from 9 months to 5 years and 8 months. Nerve function of 8 cases recovered completely or nearly completely; that of 2 cases improved apparently and that of 2 cases improved slightly. Conclusion Detailed disease history collection, particular body examination and MR reading are very important to early diagnosis of cervical spondylotic myelopathy combined with thoracic spinal stenosis. Early operation combined with cervical and thoracic spinal canal decompression at same time or at different stages is the single effective method to patients’ function recovery.展开更多

Methods: Seventy-eight patients with thoracolumbar burst fractures were retrospectively reviewed to calculate the stenotic ratio of spinal canal based on the midsagittal diameters and the hyphosis angle according to Cobb. The ASIA scoring of motor function of lower extremities was recorded . Results: The differences (P > 0.05) of the stenotic ratio of spinal canal and the kyphosis angle were not significant between patients without neurological deficit, with incomplete and complete lesions. No significant correlation(P > 0.05) between the stenotic ratio of spinal canal and the kyphosis angle, and ASIA scoring was noted. Conclusion:The severity of spinal cord injuries in thoracolumbar burst fractures is not predicted according to the percentage of canal stenosis or the degree of kyphesis induced by thoracolumbar burst fractures.展开更多

Methods: From June 2011 to August 2016, 24 patients with mono-segmental thoracic spine tuberculosis were treated by transfacet debridement combined with bone grafting and internal fixation through paraspinal approach. There were 11 males and 13 females with age ranging from 21 to 63 years (average, 39.5). There were 3 patients in T4/5, 2 patients in T5/6, 3 patients in T7/8, 3 patients in T8/9, 4 patients in T9/10, 3 patients in T10/11, and 6 patients in T11/12. Patients had different degraded local kyphosis deformity shown on X-ray, and different degraded bone destruction and abscess in thoracic spine shown on CT and MRI before the operation. All of the patients before the regular anti tuberculosis treatment for 2 to 4 weeks, the surgical approach used by paraspinal muscle approach, postoperative regular anti tuberculosis treatment for 9 to 12 weeks. Record the clinical symptoms of patients before and after surgery, preoperative Frankel functional classification of spinal cord injury, the operative time, intraoperative blood loss, postoperative ESR, CRP, complications, VAS score, ODI score and Cobb angle changes, imaging check regularly to evaluate the fusion and follow-up of nerve functional recovery. Results: The average operation time was 198 min. The average blood loss was 436 ml. There were no severe complications during and after operation. All patients were followed up for 1 year to 2 years, average 1.5 years of follow-up, the clinical symptoms improved significantly after operation and last follow-up ESR, CRP, VAS score, ODI score and Cobb angle were significantly improved after operation (P < 0.05), grade I Eck fusion, the fusion rate was 100% and the neurological function were improved. Conclusion: on the basis of strict anti tuberculosis chemotherapy, the use of paraspinal muscle gap approach for the treatment of thoracic tuberculosis is less invasive, less destructive to spinal stability, and can achieve obvious curative effect. It is worthy of clinical application.展开更多
