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.

Review Meta Analysis
The polymorphisms of melatonin receptor 1B gene (MTNR1B) (rs4753426 and rs10830963) and susceptibility to adolescent idiopathic scoliosis: a meta-analysis.
To determine whether MTNR1B rs4753426 and rs10830963 polymorphisms are correlated with AIS. Adolescent idiopathic scoliosis (AIS) is the most common form of spinal deformity, while its etiology remains uncertain. Melatonin receptor 1B (MTNR1B) gene polymorphisms have been found to be significantly associated with AIS risk; however, some of these results are controversial. ⋯ MTNR1B rs4753426 and MTNR1B rs10830963 polymorphisms are not obviously associated with risk of AIS in either Asian populations or Caucasian populations.

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.

Randomized Controlled Trial
Intramedullary nailing versus minimally invasive plate osteosynthesis for distal extra-articular tibial fractures: a prospective randomized clinical trial.
The purpose of this randomized clinical trial is to compare intramedullary nailing (IMN) versus minimally invasive plate osteosynthesis (MIPO) for the treatment of extra-articular distal tibial shaft fractures. ⋯ Results of our study showed that both treatment methods have similar therapeutic efficacy regarding functional outcomes and can be used safely for extra-articular distal tibial shaft fractures, and none of the techniques had a major advantage over the other.

Chronic pain affects between 10-20 % of the population of Japan and several specific types of chronic pain have been found to be associated with worse health outcomes. The aim of the current study was to investigate the economic burden of chronic pain as well as the health status among Japanese patients. ⋯ The results suggest that chronic pain has a significant association in an individual's health status, work productivity, daily activity impairment, healthcare resource use, and economic burden in Japan. Along with low treatment rates, a multidisciplinary approach may lead to an improved quality of life and reduce the economic burden among patients with chronic pain in Japan.
