The purpose of this study was to investigate the impact of various methods on the assessment of vertebral bone quality. ⋯ CT produced values more closely related to DEXA, while MRI was less reliable for osteoporosis/osteopenia screening. On CT, there was no benefit to making multiple measurements for each vertebral body to calculate a composite. Measuring sagittal CT images produced values similar to axial and required less time. While assessing bone quality from existing images rather than getting an additional DEXA scan is appealing, the methods of measuring these images needs standardization to maximize their utility.

Fear avoidance beliefs questionnaire (FABQ), Tampa scale of kinesiophobia (TSK), and pain catastrophizing scale (PCS) are tools widely used to measure fear-avoidance beliefs, fear of movement, and pain-related catastrophic thinking in people with chronic spinal disorders. ⋯ The results of this study demonstrated that the Persian version of FABQ, TSK, and PCS have sufficient responsiveness and good ability to measure meaningful clinical changes in people with patient CNNP. The MIC scores of the FABQ, TSK, and PCS can help clinicians and researchers to detect changes significant to the patient following a rehabilitation program.

Orthopaedic patient education materials (PEMs) have repeatedly been shown to be well above the recommended reading level by the National Institute of Health and American Medical Association. The purpose of this study is to create a standardized method to improve the readability of PEMs describing spine-related conditions and injuries. It is hypothesized that reducing the usage of complex words (≥ 3 syllables) and reducing sentence length to < 15 words per sentence improves readability of PEMs as measured by all seven readability formulas used. ⋯ The current study shows that using this standardized method significantly improves the readability of spine-related PEMs and significantly increased the likelihood that PEMs will meet recommendations for being at or below the sixth-grade reading level.

To determine: (1) the smallest change in function patients would need to see following a self-management intervention for low back pain (LBP) to consider it worthwhile; (2) the association between patient-related factors and the magnitude of the smallest worthwhile change. ⋯ On average, an improvement of 9.4 points (or 31%) in function is considered by people with LBP as the smallest change that makes self-management worthwhile. Those with lower levels of function needed to experience greater improvements.

To compare the safety and accuracy of cannulated pedicle screw placement using a robotic-navigation technique, O-arm-based navigation technique, or freehand technique. ⋯ The robotic-navigation and O-arm-based navigation techniques effectively increased the accuracy and safety of pedicle screw insertion alternative to the freehand technique in scoliosis surgery. Compared with the O-arm-based navigation technique, the robotic-navigation technique increases the mean operation time, but also increases the accuracy of pedicle screw placement. A three-dimensional scan after insertion of the K-wire may increase the accuracy of pedicle screw placement in the O-arm-based navigation technique.
