To present three identified novel COL2A1 mutations causing spondyloepiphyseal dysplasia congenita (SEDC) in three unrelated Chinese families, and perform analysis regarding the clinical and genetic features of SEDC in the Chinese population through assessment of the literature. ⋯ Our study contributed to the further expansion of the COL2A1 mutation spectrum and provided more information concerning SEDC in the Chinese population through literature review.

The assessment of a broad range of biopsychosocial aspects is important in the rehabilitation of patients with chronic low back pain (CLBP) for the prediction of outcome as well as for evaluation. The objective of this study was to test the responsiveness, construct validity and predictive value of the Örebro Musculoskeletal Pain Screening Questionnaire (OMPSQ) compared to other instruments widely used to assess biopsychosocial aspects in patients with CLBP. ⋯ The OMPSQ can also be applied in patients with CLBP, but for the assessment of change in psychosocial variables one should add specific questionnaires.

Grading inter-vertebral disc degeneration (IDD) is important in the evaluation of many degenerative conditions, including patients with low back pain. Magnetic resonance imaging (MRI) is considered the best imaging instrument to evaluate IDD. The Pfirrmann classification is commonly used to grade IDD; the authors describing this classification showed an adequate agreement using it; however, there has been a paucity of independent agreement studies using this grading system. The aim of this study was to perform an independent inter- and intra-observer agreement study using the Pfirrmann classification. ⋯ In this independent study, the Pfirrmann classification demonstrated an adequate agreement among different observers and by the same observer on separate occasions. Furthermore, it allows communication between radiologists and spine surgeons.

Comparative Study
Preclinical evaluation of posterior spine stabilization devices: can the current standards represent basic everyday life activities?
To discuss whether the available standard methods for preclinical evaluation of posterior spine stabilization devices can represent basic everyday life activities and how to compare the results obtained with different procedures. ⋯ The study increases our awareness on the use of the current standards to achieve meaningful results easy to compare and interpret.

The most relevant musculoskeletal problems are related with back health. Study instruments have been designed for adult patient population but not for school-aged children. The aim of this study was to develop and evaluate the psychometric properties of a questionnaire to assess adolescents' level of back care knowledge in daily life physical activities. ⋯ The questionnaire showed acceptable psychometric values. Results showed that this questionnaire is a good instrument to assess adolescent's back care knowledge.
