Materials and Methods: Seven patients with ages ranging from 40-80 showed conus medullaris syndrome due to thoracolumbar problems. Thoracic disc herniation: 2, Failed back syndrome: 2. Adjacent problems after PLIF: 2. Both cord decompression and insertion of interbody fusion cages could safely be completed by unilateral facetectomy using distraction force on the pedicle screws. Results: All patients showed improvement of urinary and gait disturbance without complications. Bony fusion was checked and followed by postoperative CT and the vertebral intensity around cages became higher within one month. Conclusions: This approach is an application of \"TLIF (transforaminal lumbar interbody fusion)\" reported by Harms(Germany). This safe and solid fusion with decompression technique has no necessity for the opening of abdominal and thoracic cavities and it is very useful for aged and patients.","PeriodicalId":283326,"journal":{"name":"Spinal Surgery","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122359145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objectives: To emphasize that some patients lumbar stenosis/radiculopathy may also be myelopathic, and should undergo MR evaluations of the cervical/ thoracic spine. Summary of Background Data: Patients presenting with the diagnosis of lumbar spinal stenosis supported by MR studies should be fully examined to determine whether thoracic myelopathy is superimposed on lumbar radiculopathy. Methods: Three patients presented with MR-documented lumbar spinal stenosis/spondyloarthrosis, and ossification of the yellow ligament [OYL]. However, when all 3 also exhibited severe thoracic myelopathy/parapareses, they underwent thoracic MR/CT studies which documented; [1] TI0/11 right-sided disc, and severe stenosisIOYL T9-T12 OYL [mild/moderate L3-SI OYL was not operated upon-1 patient], [2] T9/10 and TI0/1 1 synovial cysts, and severe stenosis T8-SI OYL [1 patient], and [3] TI0/1 1 synovial cyst and severe stenosisIOYL TIO-S I [1 patient]. Results: The first patient underwent a TI0/1 1 right-sided diskectomy, and T9-T12 Iaminectomy alone. Two patients had thoracic laminectomies for synovial cysts/OYL, and lumbar laminectomies for severe stenosis/OYL; T8-SI and T9-Sl. Utilizing Odom's criteria, 2 patients exhibited excellent outcomes 6 and 9 months, while I demonstrated a fair/good recovery [T8-S I Iaminectomy] 3 months postoperatively. Conclusions: A subset of patients with MR-documented lumbar spinal stenosis/radiculopathy may exhibit simultaneous thoracic myelopathy. Where thoracic cord compression is documented, thoracic/thoracolumbar laminectomies may become warranted.","PeriodicalId":283326,"journal":{"name":"Spinal Surgery","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128257764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we asked what morbidity would be encountered utilizing dynamic plates for 31 single level anterior diskectomy and fusion procedures. Thirty-one patients undergoing 1 level ADF averaged 45 years of age and included 18 males, 13 females, and 12 smokers [Table I]. Patients exhibited moderate myelopathy attributed to MR/CT documented disc herniations [ten], spurs/ossification of the posterior longitudinal ligament [OPLL] [seven], or both [fourteen]. Iliac crest autografts, dynamic plates, and cervicothoracic orthoses [CTO] were utilized [until fused]. Patients were followed an average of 2.6 years [minimum 1 year]. Two independent neuroradiologists confirmed fusion utilizing both dynamic X-rays and 2D-CT studies [2.5-12 mo postoperatively]. SF-36 outcomes were also assessed [preoperatively- 1 year postoperatively]. Postoperatively, patients’ myelopathy improved an average of 3 Nurick Grades. Although all patients fused [dynamic X-ray/2D-CT] an average of 3.6 months postoperatively, 2 female smokers demonstrated delayed fusions [7, 8 months], and one required secondary surgery 5 years later for adjacent level disease. Utilizing dynamic plates, although all 31 single level ADF patients fused [average 3.6 months postoperatively], 2 demonstrated delayed fusions [7, 8 months], and one developed adjacent segment disease 5 years later warranting secondary arthrodesis.
