Purpose: This was conducted to assess the need for conventional radiographs of the thoracolumbar spine for routine screening of trauma patients who revealed no spinal trauma on chest and abdominal computed tomography (CT). Methods: We performed a retrospective review of the medical records of trauma patients who underwent conventional radiographs of the thoracolumbar spine following a chest and abdominal CT that revealed no spinal trauma. Results: Two hundred seventy-five trauma patients underwent conventional radiographs of the thoracolumbar spine following a chest and abdominal CT that revealed no spinal trauma. In 274 of the cases, the thoracolumbar spine series was also negative. Conclusion: CT of the chest and abdomen is an adequate evaluation of the thoracolumbar spine in trauma patients who require routine thoracolumbar spine screening, making subsequent conventional radiographs of the thoracolumbar spine unnecessary.

Fractures at the thoracolumbar region are commonly followed after major traumatic injuries, and up to 20% of these fractures are known to be burst fractures. Making surgical decisions for these patients are of great interest however there is no golden standard so far. Since the introduction of Thoracolumbar Injury Classification and Severity (TLICS) score in 2007, it has been widely used as a referential guideline for making surgical decisions in thoracolumbar fractures. However, there is still limitations in this system. In this clinical case report, we introduce a L1 burst fracture after motor vehicle injury, who was successfully treated conservatively even while she was graded as a TLICS 5 injury. A case report is presented as well as discussion on the limitations of this grading system.

Objective : Thoracoscopic spinal surgery provides minimally invasive approaches for effective vertebral decompression and reconstruction of the thoracic and thoracolumbar spine, while surgery related morbidity can be significantly lowered. This study analyzes clinical results of thoracoscopic spinal surgery performed at our institute. Methods : Twenty consecutive patients underwent video-assisted thoracosopic surgery (VATS) to treat various thoracic and thoracolumbar pathologies from April 2000 to July 2006. The lesions consisted of spinal trauma (13 cases), thoracic disc herniation (4 cases), tuberculous spondylitis (1 case), post-operative thoracolumbar kyphosis (1 case) and thoracic tumor (1 case). The level of operation included upper thoracic lesions (3 cases), midthoracic lesions (6 cases) and thoracolumbar lesions (11 cases). We classified the procedure into three groups: stand-alone thoracoscopic discectomy (3 cases), thoracoscopic fusion (11 cases) and video assisted mini-thoracotomy (6 cases). Results : Analysis on the Frankel performance scale in spinal trauma patients (13 cases), showed a total of 7 patients who had neurological impairment preoperatively : Grade D (2 cases), Grade C (2 cases), Grade B (1 case), and Grade A (2 cases). Four patients were neurologically improved postoperatively, two patients were improved from C to E, one improved from grade D to E and one improved from grade B to grade D. The preoperative Cobb's and kyphotic angle were measured in spinal trauma patients and were $18.9{\pm}4.4^{\circ}$ and $18.8{\pm}4.6^{\circ}$, respectively. Postoperatively, the angles showed statistically significant improvement, $15.1{\pm}3.7^{\circ}$ and $11.3{\pm}2.4^{\circ}$, respectively(P<0.001). Conclusion : Although VATS requires a steep learning curve, it is an effective and minimally invasive procedure which provides biomechanical stability in terms of anterior column decompression and reconstruction for anterior load bearing, and preservation of intercostal muscles and diaphragm.

Objective : For improving the drawbacks of previous thoracolumbar spine trauma classification, the Spine Trauma Study Group was developed new classification, Thoracolumbar Injury Classification and Severity Score (TLICS). The simplicity of this scoring system makes it useful clinical application. However, considering criteria of Korean Health Insurance Review and Assessment Service (HIRA), the usefulness of TLICS system is still controversial in the treatment decision of thoracolumbar spine injury. Methods : Total 100 patients, who admitted to our hospital due to acute traumatic thoracolumbar injury, were enrolled. In 45, surgical treatment was performed and surgical treatment was decided following the criteria of HIRA in all patients. With assessing of TLICS score and Denis's classification, the treatment guidelines of TLICS and Denis's classification were applied to the criteria of Korean HIRA. Results : According to the Denis's three-column spine system, numbers of patients with 2 or 3 column injuries were 94. Only 45 of 94 patients (47.9%) with middle column injury fulfilled the criteria of HIRA. According to TLICS system, operation required fractures (score>4) were 31 and all patients except one fulfilled the criteria of HIRA. Conservative treatment required fractures (score<4) were 52 and borderline fracture (score=4) were 17. Conclusion : The TLICS system is very useful system for decision of surgical indication in acute traumatic thoracolumbar injury. However, the decision of treatment in TLICS score 4 should be carefully considered. Furthermore, definite criteria of posterior ligamentous complex (PLC) injury may be necessary because the differentiation of PLC injury between TLICS score 2 and 3 is very difficult.

Objective : In a variety of thoracolumbar diseases, corpectomy followed by interbody bone graft and anterior instrumentation has allowed direct neural decompression and reconstruction of the weight-bearing column by short segments fusion. In this study, we compared spinal stability of the two different anterior thoracolumbar instruments : Z-plate and Kaneda device representing plate and two-rods type, respectively. Methods : A retrospective review was performed for all the patients with thoracolumbar diseases or traumas treated with anterior corpectomy, autologous iliac bone graft, and fixation with instruments from 1996 to 2000. For the anterior instrumentation, Z-plate or Kaneda device was used for 24 [M:F=5:9, average age=37] and 12 [M:F=9:3, average age=41] patients, respectively. The plain AP and lateral flexion-extension films were taken immediately after surgery and at each follow-up. The sagittal and coronal Cobb's angles at the operation segments were used to observe the change of initial fixation status. The surgical time length and bleeding amount of the two groups were compared. Intra-operative and post-operative instrument associated complications were evaluated. Student t-test was used for statistical analysis and p-value less than 0.05 was considered to be significant. Results : Mean follow-up durations for Z-plate and Kaneda device were 24 and 21 months, respectively. The fusion rate was 91% for Z-plate and 100% for Kaneda device. Two cases of Z-plate group showed instrumentation failure during the follow up period, in which additional surgery was necessary. The mean differences of sagittal Cobb's angles among the AP images immediate after surgery and at follow-up were 7 and 2 degrees for Z-plate and Kaneda device, respectively [p<0.05]. The mean differences of coronal Cobb's angles were 5 and 2 degrees for Z-plate and Kaneda device, respectively [p<0.05]. No Intra-operative complication has occurred in both groups. There was no difference in surgery time and bleeding amount between two groups. Conclusion : We think that Kaneda device [rod type] is stronger than Z-plate [plate type] to keep the spinal stability after anterior thoracolumbar surgery.

The Korean Society of Radiology and the National Evidence-based Healthcare Collaborating Agency developed a primary imaging test for suspected traumatic thoracolumbar spine injury. This guideline was developed using an adaptation process involving collaboration between the development committee and the working group. The development committee, consisting of research methodology experts, established the overall plan and provided support on research methodology. The working group, composed of radiologists with expertise in musculoskeletal imaging, wrote the recommendation. The guidelines recommend that thoracolumbar spine computed tomography without intravenous contrast enhancement be the first-line imaging modality for diagnosing traumatic thoracolumbar spine injury in adults.

Traumatic diaphragm hernia can occur in rare cases and generally accompanies thoracic or abdominal injuries. When suffering from ankylosing spondylitis, a small force can develop into vertebral fracture and an adjacent structural injury, and lead to diaphragm hernia without accompanying concomitant thoracoabdominal injury. A high level of suspicion may be a most reliable diagnostic tool in the detection of a diaphragm injury, and we need to keep in mind a possibility in a patient with ankylosing spondylitis and a thoracolumbar fracture, even in the case of minor trauma.

Purpose: We evaluate the characteristics of vertebral body fractures in two level flexion-distraction injuries of the thoracolumbar spine Methods: The findings of radiographs, computed tomographs, and MRIs of 43 patients with flexion-distraction injuries combined with vertebral body fractures were retrospectively evaluated. We divided the patients with bursting fractures into two groups, the distractive group (posterior vertebral height ratio >1) and the compressive group (vertebral height ratio <1). Results: There were 23 compression fractures and 20 bursting fractures. In bursting fractures, the distractive group had 5 cases, and the compressive group 15 cases. In 24 cases (55.8%), the interspinous distances were widened. The average of the canal encroachment was 4% in the distractive group and 40% in the compressive group. At last follow-up, the average loss of correction was 2.0 degree in compression fractures and 2.7 degree in bursting fractures. Conclusion: The configurations of vertebral body fractures in flexion-distraction injuries of the thoracolumbar spine were varied as to the location of the axis of flexion. Because bursting fractures in flexion-distraction injuries had distractive or compressive features, one should consider that in establishing operative plan.

Objective : To retrospectively analyze the clinical characteristics and surgical experience of 10 adults with spinal extradural meningeal cysts (SEMCs) in the thoracolumbar spine which may further provide evidence for surgical decision-making. Methods : Ten adults with SEMCs in the thoracolumbar spine were surgically treated and enrolled in this study. Clinical manifestations, imaging data, intraoperative findings and postoperative outcome were recorded. Results : Clinical manifestations of SEMCs included motor and sensory dysfunction of the lower limbs and urination and defecation disturbance. The cysts presented as intraspinal occupying lesions dorsal to the spine, ranging from the T8 to L3 level. Defects of eight cases were found on preoperative magnetic resonance imaging (MRI). Selective hemilaminectomy or laminectomy were used to reveal the defect within the cyst, which was further sutured with microscopic technique. The final outcome was excellent or good in seven cases and fair in three cases. No recurrence was observed during follow-up. Conclusion : SEMCs are rare intraspinal cystic lesions. Radiography and MRI are clinically practical methods to assess defects within SEMCs. Selective hemilaminectomy or laminectomy may reduce surgical trauma. Detection and microscopic suturing of the defects are the key steps to adequately decompress the nervous tissue and prevent postoperative recurrence.

Purpose: Traumatic vertebral injuries have a prevalence of 4-5% at level I centers. Studies have demonstrated that isolated thoracolumbar transverse process fractures (iTPF) rarely require brace or surgical interventions. We hypothesized that similarly isolated thoracolumbar spinous process fractures (iSPF) would have less need for bracing and operative interventions than SPFs with associated vertebral body (VB) fractures (SPF+VB). We performed a similar analysis for iTPF compared to transverse process fractures associated with VB injury (TPF+VB). Methods: In this single-center, retrospective study from 2012 to 2016, patients were classified into iSPF, SPF+VB, iTPF, and TPF+VB groups. Data including the fracture pattern, neurologic deficits, and operative intervention were obtained. The primary outcome studied was the need for bracing and/or surgery. A statistical analysis was conducted. Results: Of 98 patients with spinous process fractures, 21 had iSPF and 77 had SPF+VB. No iSPF patients underwent surgery, whereas 24 (31.17%) SPF+VB patients did undergo surgery (p=0.012). In the iSPF group, three patients (15%) received braces only for comfort, whereas 37 (48.68%) of the SPF+VB group required bracing (p=0.058). Of 474 patients with transverse process fractures, 335 had iTPF and 139 had TPF+VB. No iTPF patients underwent surgery, whereas 28 (20.14%) TPF+VB patients did (p≤0.001). Of the iTPF patients, six (1.86%) were recommended to receive braces only for comfort, while 68 (50.75%) of the TPF+VB patients required bracing (p<0.001). Conclusions: No patients with iSPF or iTPF required surgical intervention, and bracing was recommended to patients in these groups for comfort only. It appears that these injures may be safely managed without interventions, calling into question the need for spine consultation.
