The clinical syndrome of lumbar spinal stenosis (LSS) is a commonly diagnosed lumbar condition associated with pain and disability. Psychological factors, including depression, also affect these and other health-related outcomes. Yet, the prognostic value of depression specifically in the context of LSS is unclear. ⋯ Findings support that preoperative depression is likely a prognostic factor for postoperative LSS-related symptom severity and disability at various follow-up points. The prognostic value of depression on the outcomes of pain and walking capacity is less clear. Nonetheless, depression should be considered in the clinical care of this population.

The fear-avoidance model offers a promising framework for understanding the development of chronic postoperative pain and disability. However, limited research has examined this model in patients undergoing spinal surgery. ⋯ Results provide support for the fear-avoidance model in a postsurgical spine population. Early postoperative screening for fear of movement and depressive symptoms that do not acutely improve following surgical intervention appears warranted. Cognitive and behavioral strategies may be beneficial for postsurgical patients with high fear of movement and/or depressive symptoms.

Prevention of low back pain in the military cluster randomized trial: effects of brief psychosocial education on total and low back pain-related health care costs.
Effective strategies for preventing low back pain (LBP) have remained elusive, despite annual direct health care costs exceeding $85 billion dollars annually. In our recently completed Prevention of Low Back Pain in the Military (POLM) trial, a brief psychosocial education program (PSEP) that reduced fear and threat of LBP reduced the incidence of health care-seeking for LBP. ⋯ The results of this study will help to inform policy- and decision-making regarding the feasibility of implementing psychosocial education in military training environments across the services. It would be interesting to explore in future research whether cost savings from psychosocial education could be enhanced given a more individualized delivery method tailored to an individual's specific psychosocial risk factors.

C2 pedicle screws provide stable fixation for posterior cervical fusion. Placing C2 pedicle screws is fraught with risks, and a misplaced screw can result in cortical breach of the pedicle, resulting in injury to the vertebral artery or spinal cord. ⋯ It is possible to determine an ideal trajectory through the C2 pedicle. These measurements may facilitate C2 pedicle screw fixation decreasing the risk of injury to the vertebral artery, spinal cord, or nerve roots. Delineating the individual anatomy in each case with imaging before surgery is recommended.
