Multicenter StudyPulmonary function changes after various anterior approaches in the treatment of adolescent idiopathic scoliosis.
Prospective radiographic and chart review of pulmonary function in patients who underwent 3 different anterior spinal surgery approaches for adolescent idiopathic scoliosis (AIS). ⋯ Slight declines in pulmonary function at 2-year follow-up were noted in both the thoracotomy and thoracoscopic groups, but to a significantly greater extent in those with an open thoracotomy. Significantly greater impairment in pulmonary function was seen in thoracoscopic patients who underwent thoracoplasty, whereas those without thoracoplasty either had no significant declines at 2 years or experienced slight but significant improvement. No significant diminishment was noted for the thoracoabdominal approach, despite disruption of the diaphragm.

Comparative StudyThe effect of screw length and bone cement augmentation on the fixation strength of iliac screws: a biomechanical study.
Comparison of the biomechanical fixation strengths offered by 3 iliac screw fixation techniques: short screw, short screw augmented with cement, and long screw. ⋯ Short iliac screws are susceptible to loosening after cyclic loading. Bone cement augmentation of short screws has demonstrated a significant increase in the fixation strength of short screws to an extent similar to that of long iliac screws. Thus, short iliac screw fixation after augmentation with bone cement will be a viable clinical option for spino-pelvic reconstruction.

Comparative StudyAnterior exposure of the lumbar spine with and without an "access surgeon": morbidity analysis of 265 consecutive cases.
Retrospective review ⋯ Our results do not support the notion that the presence of an "access" surgeon will change the type and rate of complications. With adequate training and judgment, spine surgeons may safely perform such exposures, provided vascular surgical assistance is readily available.

Case ReportsNovel fluoroscopic technique for localization at cervicothoracic levels.
To use a novel modified intraoperative fluoroscopic view for spinal level localization. ⋯ The modified oblique cross table fluoroscopy technique allows accurate operative localization across the cervicothoracic junction and well into the thoracic spine.

One-staged combined cervical and lumbar decompression for patients with tandem spinal stenosis on cervical and lumbar spine: analyses of clinical outcomes with minimum 3 years follow-up.
Retrospective study of clinical outcomes of 1-staged combined cervical and lumbar decompression for patients with tandem spinal stenosis (TSS). ⋯ One-staged combined cervical and lumbar decompression for TSS provided fair results, even for elderly patients. Although reasons other than spinal pathology affected symptom deterioration at final follow-up, most patients expressed satisfaction at middle-term follow-up periods.
