The use of cage and plate construct in 2-level ACDF results in a shorter fusion duration and a lower subsidence rate than that of cage alone; however, there is no significant difference in the postoperative global and segmental alignment and clinical outcomes between groups.

ObjectiveThe beneficial effect of decompressive craniectomy in the treatment of severe traumatic brain injury (TBI) is controversial, but there is no debate that decompression should be performed before irreversible neurological deficit occurs. The aim of our study was to assess the value of ultra-early decompressive craniectomy in patients with severe TBI.MethodsTotal of 127 patients who underwent decompressive craniectomy from January 2007 to December 2013 was included in this study. Among them, 60 patients had underwent ultra-early (within 4 hours from injury) emergent operation for relief of increased intracranial pressure. Initial Glasgow coma scale, brain computed tomography (CT) scan features by Marshall CT classification, and time interval between injury and craniectomy were evaluated retrospectively. Clinical outcome was evaluated, using the modified Rankin score.ResultsThe outcomes of ultra-early decompressive craniectomy group were not better than those in the comparison group (p=0.809). The overall mortality rate was 68.5% (87 patients). Six of all patients (4.7%) showed good outcomes, and 34 patients (26.8%) remained in a severely disabled or vegetative state. Forty of sixty patients (66.7%) had died, and two patients (3.3%) showed good outcomes at last follow-up.ConclusionUltra-early decompressive craniectomy for intracranial hypertension did not improve patient outcome when compared with "early or late" decompressive craniectomy for managing severe TBI.

PSCT in pediatric patients can be surgically removed with an acceptable low surgical morbidity. Progression-free survival was found to be related to the grade of tumor and the extent of tumor resection. Early diagnosis and treatment anticipate good functional neurologic outcome.

ObjectiveTo evaluate radiologic result of anterior cervical discectomy and fusion with allobone graft and plate augmentation, and the change of radiologic outcome between screw type and insertion angle.MethodsRetrospective review of clinical and radiological data of 29 patients. Segmental angle, height and screw angles were measured and followed. The fusion rate was assessed by plain radiography and CT scans. We divided the patients into two groups according to screw type and angles. Group A: fixed screw, Group B: variable screw. Interscrew angle was measured between most upper and lower screws with Cobb's methods.ResultsOverall fusion rate was 86.2% on plain radiography. Fusion was also assessed by CT scan and Bridwell's grading system. There was no difference in fusion and subsidence rates between two groups. Subsidence was found in 5 patients (17.2%). Segmental lordotic angle was increased from preoperative status and maximized at the immediate postoperative period and then reduced at 1 year follow up. Segmental height showed similar increase and decrease values.ConclusionACDF with allograft and plate showed favorable fusion rates, and the screw type and angle did not affect results of surgery.
