Perhaps the single greatest error that a surgeon hopes to avoid is operating at the wrong site. In this report, the authors describe the incidence and possible determinants of incorrect-site surgery (ICSS) among neurosurgeons. ⋯ Neurosurgical ICSSs do occur, but are rare events. Although there are significant limitations to the survey-based methodology, the data suggest that the prevention of such errors will require neurosurgeons to recognize risk factors and increase the use of intraoperative imaging.

Although clinical guidelines for sciatica have been developed, various aspects of lumbar disc herniation remain unclear, and daily clinical practice may vary. The authors conducted a descriptive survey among spine surgeons in the Netherlands to obtain an overview of routine management of lumbar disc herniation. ⋯ Unilateral transflaval discectomy was the most frequently performed procedure. Minimally invasive techniques were expected to be less effective, with higher recurrence rates but less postoperative low-back pain. Variety was shown between surgeons in the management of patients with neurological deficit. Most responding surgeons allowed early mobilization but appeared to give conservative advice in resumption of work.

Increased signal intensity of the spinal cord on magnetic resonance (MR) imaging was classified pre- and postoperatively in patients with cervical compressive myelopathy. It was investigated whether postoperative classification and alterations of increased signal intensity could reflect the postoperative severity of symptoms and surgical outcomes. ⋯ The postoperative increased signal intensity classification reflected postoperative symptomatology and surgical outcomes to some extent, without statistically significant differences. The alteration of increased signal intensity was seen postoperatively in 24 patients (23%) and was not correlated with surgical outcome.

Cervical kyphosis in patients with ankylosing spondylitis (AS) can be severely disabling. Surgical treatment of this disorder is technically demanding, however, with a considerable risk of neurological and vascular injuries. The extension osteotomy is a well-described posterior treatment for this condition, but this approach presents the risk of acute subluxation and spinal column translation during the reduction. ⋯ Controlled correction was performed by using a hinged rod affixed to posterior cervical and thoracic screws, allowing for free sagittal correction while restricting translational forces. Once the desired angle of correction was achieved, the hinge connector was locked, transforming the rod into a rigid device for permanent internal fixation. The use of hinged rods in cervical kyphosis correction provides a controlled method for reduction at the osteotomy site, decreasing the risk of neurological injury.
