It has been hypothesised that attentional bias to environmental threats can contribute to persistent pain. It is unclear whether people with acute low back pain (LBP) have an attentional bias to environmental threats. We investigated if attentional bias of threat related words is different in people with acute LBP and pain-free controls. ⋯ When compared with pain-free controls, people with acute LBP looked more often at affective pain words relative to neutral control words. This may indicate a form of engagement bias for people with acute LBP. Attentional bias was not consistent across outcome measures or word groups. Further research is needed to investigate the potential role of attentional bias in the development of persistent pain.

Reported data indicate that the curative effect of percutaneous vertebroplasty (PVP) on the patients with intravertebral vacuum cleft (IVC) is worse than on those without IVC. ⋯ RC-PVP, with the destruction of IVC, may lead to better clinical outcomes with fewer complications.
