Effects of glucosamine in patients with osteoarthritis of the knee: a systematic review and meta-analysis.

Osteoarthritis (OA) of the knee is one of the main causes of mobility decline in the elderly. Non-surgical treatments such as administration of supplements to strengthen the joint cartilage matrix have become popular not only for pain relief but also for joint preservation. Glucosamine has been used in many countries based on the increasing evidence of its effectiveness for OA.

D-dimer predicts pulmonary embolism after low-risk spine surgery.

Introduction: Pulmonary embolism (PE) is a risk of mortality following spine surgery. Many studies have demonstrated that deep venous thrombosis (DVT) may affect and actually advance to PE, but few studies have shown how venous thromboembolism (VTE), including PE and DVT, affect blood markers after spine surgery. In this study, we examined changes in blood markers with PE or DVT after low-risk spine surgery, namely cervical laminoplasty or lumbar laminectomy.

The 25-question Geriatric Locomotive Function Scale predicts the risk of recurrent falls in postoperative patients with cervical myelopathy.

Background: Fall-induced injuries represent a major public health concern for older individuals. The relationship between risk of falling and the severity of locomotive syndrome (LS) remains largely unknown.

Methods: We conducted a retrospective analysis of patients who had undergone surgery from January 2012 to December 2013 and completed at least 1 year of follow-up at 12 participating institutes.

Background: Ageing is associated with a decline of motor function and ability to perform daily activities. Locomotive disorders are one of the major disorders resulting in adverse health condition in elderly people. Concept of Locomotive syndrome (LoS) was proposed to tackle the problems and prolong healthy life expectancy of people with locomotive disorders.

The effect of balneotherapy on pain relief, stiffness, and physical function in patients with osteoarthritis of the knee: a meta-analysis.

This meta-analysis was performed to determine the effect of balneotherapy on relieving pain and stiffness and improving physical function, compared to controls, among patients with knee osteoarthritis. We searched electronic databases for eligible studies published from 2004 to December 31, 2016, with language restrictions of English or Japanese. We screened publications in Medline, Embase, Cochrane library, and the Japan Medical Abstracts Society Database using two approaches, MeSH terms and free words.

Relationship between physician-judged functioning level and self-reported disabilities in elderly people with locomotive disorders.

Purpose: Locomotive disorders due to musculoskeletal involvement are one of the main causes requiring long-term care services in aging Japan. "Locomotive syndrome (LoS)" is a concept referring to the condition under which people require assistance from others or at risk in future. The object of this study is to examine the relationship between self-reported measure and physician-judged degrees on ADL disability in elder people with locomotive disorders.

Fall-related Deterioration of Subjective Symptoms in Patients with Cervical Myelopathy.

Study Design: Retrospective multi-center study.

Objective: This study was conducted to clarify the incidence and neurological outcomes of fall-related deterioration of subjective symptoms in patients undergoing surgical treatment.

Summary Of Background Data: The evidence that minor trauma, including falls, increases the risk of worsening cervical myelopathy is insufficient.

Predictive Factors for Subjective Improvement in Lumbar Spinal Stenosis Patients with Nonsurgical Treatment: A 3-Year Prospective Cohort Study.

Objective: To assess the predictive factors for subjective improvement with nonsurgical treatment in consecutive patients with lumbar spinal stenosis (LSS).

Epidemiologic survey of locomotive syndrome in Japan.

Background: The authors have developed a screening tool, the 25-Geriatric Locomotive Function Scale (GLFS-25), for the early detection of locomotive syndrome (LS). However, few studies have examined the prevalence of LS in the general population. This study estimated the prevalence of LS in Japan using the GLSF-25 and investigated age specific mean values for this scale.

[Locomo 25--a screening tool for risk of locomotive syndrome].

Locomo 25 was developed as a screening tool of locomotive syndrome by Japanese orthopedic surgeon group in 2008. It contains 25 questions in terms of musculoskeletal disorder such as walking disability, difficulty in daily living, or suffering pain on body. Its reliability and validity were already confirmed through multi-center study including 731 Japanese elderly people (over 65 y.

[Lumbar spondylosis].

Lumbar spondylosis is a chronic, noninflammatory disease caused by degeneration of lumbar disc and/or facet joints. The etiology of lumbar spondylosis is multifactorial. Patients with lumbar spondylosis complain of a broad variety of symptoms including discomfort in the low back lesion, whereas some of them have radiating leg pain or neurologenic intermittent claudication (lumbar spinal stenosis).

Progression of ossification of the posterior longitudinal ligament of the thoracic spine following posterior decompression and stabilization.

Object: Despite its potential clinical impact, information regarding progression of thoracic ossification of the posterior longitudinal ligament (OPLL) is scarce. Posterior decompression with stabilization is currently the primary surgical treatment for symptomatic thoracic OPLL; however, it remains unclear whether thoracic OPLL increases in size following spinal stabilization. It is also unknown whether patients' clinical symptoms worsen as OPLL size increases.

Study design Prospective cohort study. Objective The purpose of the present study was to identify the predictors of patient satisfaction with outcome after cervical laminoplasty for compressive cervical myelopathy. Methods A cohort of 143 patients with compressive myelopathy who underwent cervical double-door laminoplasty between 2008 and 2011 was studied prospectively.

A genome-wide association study identifies susceptibility loci for ossification of the posterior longitudinal ligament of the spine.

Ossification of the posterior longitudinal ligament of the spine (OPLL) is a common spinal disorder among the elderly that causes myelopathy and radiculopathy. To identify genetic factors for OPLL, we performed a genome-wide association study (GWAS) in ∼8,000 individuals followed by a replication study using an additional ∼7,000 individuals. We identified six susceptibility loci for OPLL: 20p12.
