Selective laminoplasty after the preoperative diagnosis of the responsible level using spinal cord evoked potentials in elderly patients with cervical spondylotic myelopathy: a preliminary report.
A preliminary report of a new operative method termed selective laminoplasty after the preoperative diagnosis of the responsible level using spinal cord evoked potentials (SCEPs) in elderly patients with cervical spondylotic myelopathy. ⋯ Preliminary clinical results for selective laminoplasty were satisfactory in all but 1 case. Although long-term results are not yet available, we consider this method to be less invasive and capable of giving satisfactory clinical results and benefits for elderly patients.

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.

Major neurologic deficit immediately after adult spinal surgery: incidence and etiology over 10 years at a single training institution.
Retrospective study of adult patients who underwent spinal surgery over a 10-year period at a single institution. ⋯ The incidence of new onset major neurologic deficit immediately after adult spinal surgery is low. Epidural hematoma and inadequate decompression were the most common etiologies in this series of patients.

Comparative StudyReconstructive techniques study after anterior decompression of multilevel cervical spondylotic myelopathy.
Retrospectively compared 2 reconstructive techniques after the anterior decompression of multilevel cervical spondylotic myelopathy. ⋯ This study clearly demonstrates that, adequate decompression can be achieved for the multilevel cervical spondylotic myelopathy with both methods, and the hybrid method offers better biomechanical stability and fusion results than the corpectomy method, and obviates the need for staged circumferential procedures.

Comparative StudyMotion-preserving surgery can prevent early breakdown of adjacent segments: Comparison of posterior dynamic stabilization with spinal fusion.
A retrospective study. ⋯ Prevalence of adjacent-segment disease and reoperation rate seemed to be lower in ligamentoplasty than fusion surgeries, but the difference was not significant. Ligamentoplasty circumvented adjacent-segment disease for longer period than fusion surgeries. Although the rates of additional surgeries in PLIF and PLF were comparable, PLIF developed adjacent-level instability and required fusion surgery more frequently than PLF.
