Systematic review of literature. ⋯ There is very low quality evidence to support the superiority of one approach over another. There is a strong recommendation for posterior or posterior-lateral approach from T2 through T5. For the T6-L5 regions of the spine we recommend either anterior, posterior, or combined anterior and posterior surgery depending on the clinical presentation, surgeon and patient preference.

Systematic review. ⋯ (1) Incisional biopsy or intralesional resection significantly increases the risk of local recurrence, therefore, transcutaneous computed tomography-guided trocar biopsy is recommended. When there is a suspicion of primary spine tumor, the surgeon who performs the definitive surgery should ideally perform or direct the biopsy procedure. (2) En bloc resection is achievable if staging determines that it is feasible. The adverse event profile of these surgeries is high even at experienced centers. Therefore, experienced, multidisciplinary teams should perform these surgeries. (3) Grade of Recommendation can be "strong recommendation, low-quality evidence."

Prospective fluoroscopic and electromyographic study of coronal plane lumbar spine motion in healthy male volunteers. ⋯ These results suggest that reference limits from asymptomatic data for coronal plane passive recumbent intervertebral motion may be a useful resource for investigating the relationship between symptoms of chronic (nonspecific) low back pain and biomechanics and in the clinical assessment of patients and interventions that target the passive holding elements of the spine. Data pooling from multiple studies would be necessary to establish a complete database.

A retrospective histologic evaluation of biopsies obtained during percutaneous vertebroplasty (PVP) procedures as treatment for presumed osteoporotic vertebral compression fractures. ⋯ Obtaining bone biopsies during PVPs does not lead to increased morbidity and can verify the pathologic process underlying the vertebral compression fractures. Since this study showed an unsuspected malignancy rate of 3.8%, we recommend routine obtainment of a vertebral body bone biopsy, preferably using a biopsy needle with a diameter larger than 14 Gauge (>2.1 mm/0.083 inch), during every PVP procedure.

Technical note. ⋯ This technique greatly supports surgeons inexperienced in the anterior approach to the upper cervical spine or surgeons at revision surgery who may be lost in and daunted by an unfamiliar operation field surrounded by important structures. Although an anterior approach to the upper cervical spine in the patient with O-C fusion may rarely be required, this application should be considered.
