STUDY DESIGN: A case report. OBJECTIVES: Lumbar burst fracture was treated with operation, which delayed recollapse of L1 and led to conus medullaris syndrome. SUMMARY OF LITERATURE REVIEW: After operation, conus medullaris syndrome causing by delayed recollapse is not frequently reported. MATERIALS AND METHODS: A 56-year-old male was admitted with lower back pain caused by a fall. Radiologic findings showed L1 burst fracture with about 42% of height loss. There was no neurologic deficit. Posterior fusion was performed using instrumentation. Five weeks after the operation, the patient was admitted for urination and defecation difficulty. Radiologic findings showed that the L1 had recollapsed with about 38% of height loss. To resolve the problem, anterior surgery was performed. RESULTS: Two years after surgery, bladder and anal sphincter dysfunction wasn't recovered. CONCLUSIONS: Lumbar burst fracture should be follow up carefully until union of the fracture because burst fracture leads to delayed recollapse.

Endovascular aneurysm repair (EVAR) for the treatment of abdominal aortic aneurysm (AAA) is a widely used method, and its decreased invasiveness compared to traditional surgical repair has brought about reduced rates of morbidity and mortality. Several vascular complications related to the procedure have been reported, but non-vascular complications have rarely occurred. We report herein the case of a 78-year-old man who underwent EVAR for AAA and presented with active duodenal ulcer bleeding and acute acalculous cholecystitis as complications after the procedure. We must consider that a wide spectrum of complications may occur following EVAR, and therefore it is important to evaluate the risks of complication and to take the necessary measures to minimize them.

STUDY DESIGN: A retrospective study. PURPOSE: We investigated the risk factors in adjacent segment degeneration (ASD) after more than 5 years of follow-up of lumbar spinal fusion. OVERVIEW OF LITERATURE: There are many concerns regarding ASD followed by lumbar spinal fusion. However, there is a great deal of dispute about the risk factors. METHODS: A total of 55 patients who were followed up for more than 5 years after lumbar fusion were observed. Gender, age, residence, fusion method, number of fusion segments and radiological measurements were analyzed. In the radiological measurement, disc height, lumbar lordotic angle (LLA), fusion segment lordotic angle and fusion segment lordotic angle per level (FSLA per level) were estimated. In preoperative MRI, Pfirrmann's classification was used. The clinical result was evaluated by the criteria of Kim and Kim. Statistical univariate analysis was performed with the chi-square test by using SPSS ver. 12.0. Multivariate logistic regression analysis was conducted with SAS ver. 9. RESULTS: There were 21 patients with adjacent segment degeneration. Further, there was little relationship between ASD and gender, age, residence, fusion method, number of fusion segments, degree of preoperative adjacent disc degeneration in MRI, or preoperative and postoperative LLA. However, the frequency of ASD was significantly low in cases where FSLA per level was >15degrees (p=0.009). There was no significant relationship between ASD and the clinical result. CONCLUSIONS: In patients followed up for more than 5 years after lumbar spinal fusion, the most important factor in the prevention of ASD was the restoration of FSLA per level to >15degrees.

Degenerative disc disease has traditionally been thought of as low back pain caused by changes in the nucleus pulposus and annulus fibrous, in recent studies, however, changes in the upper and lower endplates cause degeneration of the disc, resulting in mechanical pressure, inflammatory reactions and low back pain. Recently, the bone marrow of the vertebral body-endplate-nucleus pulposus and annulus fibrous were considered as a single unit, and the relationship was explained. Once the endplate is damaged, it eventually aggravates the degeneration of the bone marrow, nucleus pulposus, and annulus fibrosus. In this process, the compression force of the annulus fibrosus increases, and an inflammatory reaction occurs due to inflammatory mediators. Hence, the sinuvertebral nerves and the basivertebral nerves are stimulated to cause back pain. If these changes become chronic, degenerative changes such as Modic changes occur in the bone marrow in the vertebrae. Finally, in the case of degenerative intervertebral disc disease, the bone marrow of the vertebral body-endplate-nucleus pulposus and annulus fibrous need to be considered as a single unit. Therefore, when treating patients with chronic low back pain, it is necessary to consider the changes in the nucleus pulposus and annulus fibrosus and a lesion of the endplate.

STUDY DESIGN: A Case report. OBJECTIVES: We report a case of thoracic intradural extramedullary tumor that has been misdiagnosed as the cerebral infarction. SUMMARY OF LITERATURE REVIEW: Spinal meningioma is one of the common spinal tumors. Clinical symptoms were characteristically progressive myelopathy, rather than radiculopathy. MATERIALS AND METHODS: A 66-year-old female patient who had a history of cerebral infarction admitted as suffering from progressive lower extremities weakness for 6 months. The patient was diagnosed and has been treated as the cerebral infarction at another hospital. However, the patient showed worsening symptoms. In magnetic resonance imaging, an intradural extramedullary space occupying mass compressing the spinal cord, between T8 and T9 level, was shown. By undergoing an operation, resected the mass. In a pathologic report, mass was confirmed to be meningioma. RESULTS: After the operation, symptoms were improved. The patient was able to walk 2 weeks after surgery. CONCLUSIONS: We report the correct diagnosis and a successful surgical treatment of myelopathy, due to thoracic myelopathy that has been misdiagnosed as the cerebral infarction in another hospital.

STUDY DESIGN: A retrospective study OBJECTIVES: Contralateral undercutting laminoplasty via a unilateral laminotomy has been performed instead of bilateral partial laminectomy in lumbar spinal stenosis. This study compared the radiographic and clinical results of undercutting laminoplasty with bilateral partial laminectomy. SUMMARY OF LITERATURE REVIEW: Less invasive surgery has become attractive for minimizing soft tissue injury and reducing the recovery time. MATERIALS AND METHODS: Twenty five patients, who underwent decompressive surgery for lumbar spinal stenosis and were followed-up more than one year, were enrolled in this study. Unilateral undercutting laminoplasty and bilateral partial laminectomy was performed in 13 and 12 cases, respectively. The blood loss was compared and the presence of instability was observed. The increase in dural cross sectional area was measured in the preoperative and postoperative CT scans. In the clinical assessment, the Oswestry disability index (ODI) and visual analogue scale (VAS) to pain was used. RESULTS: The average blood loss per segment was 273 ml and 436 ml in the laminoplasty and laminectomy group. There was no case of instability after surgery but there was a significant difference in the increase in dural cross sectional area between the two groups: 109.7 mm2 and 78.6 mm2 in the laminoplasty and laminectomy group, respectively. The preoperative and final change in the ODI and VAS scores was similar between the two groups. CONCLUSIONS: Unilateral undercutting laminoplasty is a minimally invasive procedure with less blood loss than the conventional technique and is equally effective.

STUDY DESIGN: A retrospective study OBJECTIVES: To compare the radiological and clinical outcomes of three surgical methods SUMMARY OF LITERATURE REVIEW: There were many proposed surgical treatments for lumbar degenerative kyphosis but the best treatment is still controversial. MATERIALS AND METHODS: Thirty three patients (all female) had undergone surgery. The mean age at surgery was 61.2. The average follow-up period was 34.7 months. The patients were divided into three groups. Group A included 7 cases with a correction by a posterior osteotomy, Group B included 15 with a posterior correction without an osteotomy, and Group C included 11 with combined anterior-posterior surgery. The radiographic measurements of lumbar lordosis, upper lumbar lordosis, lower lumbar lordosis, and pelvic tilt were performed before surgery, after surgery, and at the final follow-up visit. The loss of correction, complication rates and the clinical results were also compared. RESULTS: Postoperative correction of the lumbar and lower lumbar lordosis were significantly higher in group A and C than group B. The correction of upper lumbar lordosis was significantly higher in group A than group C. On the final follow-up, there was no significant difference in the loss of correction and clinical results between the three groups. The number of cases with complications in groups A, B and C was 4 (57%), 2 (13.3%) and 2 (18.2%), respectively. Two patients in group A required additional surgery. CONCLUSIONS: Groups A and C were more effective than posterior-only correction. There was no significant difference in the clinical results between the three groups but complication rate was higher in Group A than the other groups. Combined anterior and posterior surgery can be a safe and effective method for correction.
