To summarize the mechanical loading of the spine in different activities of daily living and sports. ⋯ These results may help to identify acute and long-term risks of low back pain and, thus, may guide the development of preventive interventions for low back pain or injury in athletes.

Elucidate whether it is preferable to use the reference frame (RF) middle attachment (RFMA) method over the edge of the planned pedicle screw (PS) insertion area for RF placement in the surgery for adolescent idiopathic scoliosis (AIS) with intraoperative computed tomography (CT) navigation. ⋯ The RFMA method in thoracic scoliosis surgery for AIS with intraoperative CT navigation could significantly decrease the number of CT scans and blood loss while maintaining a comparable PS perforation rate to RF placement at the distal end of the planned PS insertion range.

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.

This study aimed to investigate the changes of the posterior paraspinal muscles (PPM) and psoas muscle in patients with low back pain (LBP) over time. ⋯ The study revealed significant quantitatively muscular changes in males and females, especially in the posterior paraspinal muscles in only three years' time.

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.
