Low back pain is a common health problem encountered by various populations among different countries. This prospective study aimed to translate and cross-culturally adapt the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) into Traditional Chinese and to assess its validity, reliability and sensitivity in Chinese patients experiencing low back pain. ⋯ The Traditional Chinese version of JOABPEQ has satisfactory psychometric properties in general, including adequate clinical and construct validity, and internal consistency in assessing Southern-Chinese patients with low back pain. It is demonstrated as a sensitive outcome measure. The translated JOABPEQ is verified for its use in the local clinical setting for patient assessment and future research.

To investigate the risk factors of proximal junctional kyphosis (PJK) in Lenke 5 AIS patients after all-pedicle instrumentation and correction, and to compare the difference of radiographic and clinical outcome between PJK and Non-PJK populations. ⋯ Greater postoperative PJA, disruption of junctional ligaments, UIV at lower thoracic levels were the main risk factors for PJK in Lenke 5 AIS patients. Recommedation: Preserve junctional ligaments in those individuals with UIV located in the lower thoracic region.

The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) was developed in 2007, including the five domains of Pain-related disorder, Lumbar spine dysfunction, Gait disturbance, Social life disturbance, and Psychological disorder. It is used by physicians to evaluate treatment efficacy by comparing scores before and after treatment. However, the JOABPEQ does not allow evaluation of the severity of a patient's condition compared to the general population at a single time point. Given the unavailability of a standard measurement of back pain, we sought to establish reference scores and interquartile ranges using data obtained from a multicenter, cross-sectional survey taken in Japanese primary care settings. ⋯ Reference scores and interquartile ranges for JOABPEQ were generated based on the data from the examination data. These provide a measurement standard to assess patient perceptions of low back pain at any time point during evaluation or therapy.

Multicenter Study
Treatment status and radiographic features of patients with atypical femoral fractures.
The Japanese Orthopaedic Association (JOA) has been surveying approximately 3000 orthopedic surgery hospitals and clinics with inpatient facilities nationwide to collect information on atypical femoral fractures (AFFs) and patient characteristics since 2010. The present study aims to examine radiographic images and clarify the relationship between radiographic and patient characteristics of patients with AFF and treatment status. ⋯ Radiographic beaking was observed more frequently in patients treated with BPs than in patients not treated with BPs.
