A multidisciplinary approach has been shown to be effective for the treatment of intractable pain. However, few hospitals in Japan have established liaison clinics for such patients. In this study, we investigated the short-term results of a liaison clinic for patients with intractable chronic pain. ⋯ This liaison clinic for patients with intractable chronic pain was able to improve patient anxiety. Severe anxiety at the initial visit represented a risk factor for dropout from the clinic.

The incidence of periprosthetic femoral fractures (PFF) around a stable stem is increasing. The aim of this biomechanical study was to examine how three different methods of fixation, for Vancouver type B1 PFF, alter the stiffness and strain of a construct under various configurations, in order to gain a better insight into the optimal fixation method. ⋯ This study highlights that the inclusion of cables appears to damage the screw fixations and does not aid in construct stability. Furthermore, the degree of fracture reduction affects the whole construct stability and the bending behaviour of the fixation.

Review Meta Analysis
Diagnostic accuracy of ultrasonography in assessing meniscal injury: meta-analysis of prospective studies.
The accuracy of ultrasonography for diagnosing meniscal injury remains controversial. The aim of the present meta-analysis was to establish the role of ultrasonography in the diagnosis of meniscal injury by analyzing the data from prospectively designed studies. ⋯ Our results suggest that the diagnostic accuracy of ultrasonography for diagnosing meniscal injury is acceptable, with a high specificity but moderate sensitivity.

Multicenter Study
Patient-reported disability in the general Japanese population was associated with medical care visits for low back pain, regardless of pain intensity.
Race/ethnicity is known to affect pain severity and the emotional aspects of pain, with medical care visits also reported to differ according to race/ethnicity. It has been hypothesized that there is an interactive relationship between pain intensity and patient-reported disability and that the interactive relationships are related to medical care visits. However, it remains unclear whether the association between patient-reported disability and medical care visits for low back pain (LBP) are dependent on the pain intensity. The aims of this study were to examine the prevalence of medical care visits among members of the Japanese general population and to analyze the association between patient-reported disability and medical care visits for LBP patients, regardless of the pain intensity. ⋯ Patient-reported disability was associated with medical care visits for LBP, regardless of the pain intensity, with the results similar to those obtained for other races/ethnicities.
