Case report. ⋯ A lumbar hemangioma of the vertebral body, although rare, can cause neurogenic claudication and cauda equina syndrome. Intraoperative vertebroplasty can be an effective method of hemostasis and provide stability of the vertebra following posterior decompression.

Correlation study. ⋯ The implementation of multidisciplinary, nonsurgical spine clinics coincided closely with a significant reduction in the rate of lumbar disc surgery. The observed reduction seems most likely to be causally associated with educational activities and improved patient care provided by the clinics.

A retrospective review of 33 consecutive patients treated with posterior fusion and selective nerve root decompression for the treatment of pseudarthrosis following anterior cervical discectomy and fusion. ⋯ This is the first study to our knowledge to use standardized outcome measures to assess clinical outcome in patients treated with posterior fusion for pseudarthrosis after anterior cervical discectomy and fusion. Patients and surgeons need to understand the potential for success with this revision procedure but also be aware of the relatively high rate of continued moderate to severe pain observed in this patient population even after a solid fusion is achieved. All of the patients in this study fused with a single posterior fusion procedure, further supporting the relatively higher fusion rates observed in the literature using posterior fusion as a treatment for cervical pseudarthrosis. Our results also support the ability of surgeons to use local bone graft without iliac crest in a posterior fusion for cervical pseudarthrosis and therefore avoid the morbidity associated with iliac crest bone graft harvest.

A prospective evaluation of the effects of backpack carriage on the pulmonary function of schoolgirls without spinal deformity versus those with adolescent idiopathic scoliosis (AIS). ⋯ Pulmonary function may be more sensitive to backpack load than previously considered, especially when study participants with AIS are being considered, and the recommended loading limit of 10% body weight may not be applicable to schoolgirls with AIS.

This study examined the extraosseous and intraosseous anomalies of vertebral arteries in patients who underwent surgery of the craniovertebral junction. ⋯ In patients having osseous anomalies at the craniovertebral junction, the frequency of vertebral artery anomalies at the extraosseous and intraosseous regions is increased. With preoperative three-dimensional computed tomography angiography, we can precisely identify the anomalous vertebral artery and reduce the risk of intraoperative injury to the vertebral artery, in advance.
