An epidemiological survey conducted in Japan in fiscal year 2010 revealed a high prevalence of chronic musculoskeletal pain, low patient satisfaction with treatment, a high incidence of protracted treatment lasting a year or more, and reduced quality of life. To improve the current system for treating chronic musculoskeletal pain, it is important to identify risk factors, including patient characteristics, for developing chronic pain. Thus, we sought to determine the incidence of new chronic pain in the Japanese population, as well as the persistence rate, associated factors, and current state of treatment of chronic pain, by repeating a postal survey in a nationwide representative sample group first surveyed in 2010. ⋯ We identified risk factors related to the development of new chronic pain and the persistence of chronic pain. Countermeasures to prevent chronic pain could be especially important for the high-risk populations for understanding the pathology of chronic pain.

Some patients with mallet fractures who undergo extension block pinning complain of exposed wires, which delay their return to sports and causes inconvenience while performing tasks that require the use of hands during the early postoperative period. The purpose of this retrospective study was to present and evaluate a novel surgical procedure for mallet fractures. ⋯ Our novel surgical procedure combining closed reduction with extension block and flexion block using Kirschner wires and microscrew fixation produces good clinical results with relatively few complications.

Locking plates are an internal fixation material useful in the treatment of bone fractures, which provides effective stabilization between the plate and locking head screws (LHSs) via the locking mechanism. However, difficulty in removing LHSs is relatively common, and such cases can require long surgical procedures or use of special removal equipment. The purpose of this study was to report the incidence and risk factors for difficult removal of LHSs. ⋯ This study suggests that (1) the use of LHSs with a 3.5 mm diameter is a necessary condition for difficulty in screw removal, and that (2) longer time from internal fixation to removal, and (3) younger age, are risk factors for it. When removing LHSs with a 3.5 mm diameter, appropriate instruments and sufficient training are necessary.

This study aimed to translate and validate the STarT Back Screening Tool (SBST) in Iran. ⋯ In general, the Iranian version of the SBST performed well, and findings suggest that it is a reliable and valid measure for screening low back pain in patients with lumbar central canal stenosis in primary care settings.

The anti-seizure drug pregabalin is currently used for peripheral neuropathic pain, including degenerative lumbar disease with a neuropathic component. Although there are many reports associated with pregabalin, treatment outcome in low back pain (LBP) patients with depression remains uncertain. This study investigated the outcomes of pregabalin in LBP patients with depression. ⋯ This investigation indicated that pregabalin is safe and effective for reducing both LBP and mood disturbance in patients with depression.
