Preoperative psychological symptoms predict surgical outcomes. The impact of surgical outcomes on psychological well-being, however, has not been delineated. ⋯ Substantial improvements in psychological well-being resulted after surgery among patients with favorable spine-specific outcomes.

Multicenter Study Clinical Trial
Geographic variations in clinical presentation and outcomes of decompressive surgery in patients with symptomatic degenerative cervical myelopathy: analysis of a prospective, international multicenter cohort study of 757 patients.
Degenerative cervical myelopathy (DCM) is a progressive degenerative spine disease and the most common cause of spinal cord impairment in adults worldwide. Few studies have reported on regional variations in demographics, clinical presentation, disease causation, and surgical effectiveness. ⋯ Regional differences in demographics, causation, and surgical approaches are significant for patients with DCM. Despite these variations, surgical decompression for DCM appears effective in all regions. Observed differences in the extent of postoperative improvements among the regions should encourage the standardization of care across centers and the development of international guidelines for the management of DCM.

Randomized Controlled Trial
Patients' experience with nonsurgical treatment for lumbar spinal stenosis: a qualitative study.
Lumbar spinal stenosis (LSS) is a highly prevalent disease in older adults that causes significant limitations in walking and other daily activities. Research into optimal nonsurgical treatment approaches for LSS is lacking. ⋯ Many individuals with LSS report barriers to accessing non-surgical treatment, but may also be willing to commit to a long-term treatment strategy that includes exercise. Social support from others with LSS and from health care providers with good communication skills may facilitate compliance with treatment recommendations.

Minimally invasive lumbar spinal stenosis procedures have uncertain long-term value. ⋯ Spacers may provide a reasonably cost-effective initial treatment option for patients with lumbar spinal stenosis. Their value is expected to improve if procedure costs are lower in outpatient settings where these procedures are increasingly being performed. Decision analysis is useful for characterizing the long-term cost-effectiveness potential for minimally invasive spinal stenosis treatments and highlights the importance of complication rates and prospective health utility assessment.

Observational Study
Dynamic foraminal dimensions during neck extension and rotation in fusion and artificial disc replacement: an observational study.
Changes in the dimensions of the cervical neural foramina (CNF) are considered to be a key factor in nerve root compression and development of cervical radiculopathy. However, to what extent foraminal geometry differs between patients who underwent anterior cervical discectomy and fusion (ACDF) and those who underwent total disc arthroplasty with an artificial disc (AD) during physiological motion is largely unknown. ⋯ This study demonstrated decreases in foraminal dimensions and their range for ACDF compared with AD at the operated level. In contrast, it demonstrated increases in the range of foraminal dimensions during motion for ACDF compared with AD at the non-operated segments. Together, these data support the notion that increased mobility at the non-operated segments after ACDF may contribute to a greater risk for adjacent segment degeneration. Because of the significant presence of range variables in the findings, the current data also indicate that a dynamic evaluation is likely more appropriate for evaluation of the differences in foramina between ACDF and AD than a static evaluation.
