Comparative Study Observational Study
Contribution of catastrophizing to disability and pain intensity after osteoporotic vertebral compression fracture.
Pain catastrophizing is a key variable that contributes to disability not only in chronic pain disorders but also after trauma. However, there is little evidence concerning the effect of catastrophizing on pain intensity and disability after osteoporotic vertebral compression fracture. Therefore, the purpose of this study was to evaluate the contribution of catastrophizing to disability and pain intensity after osteoporotic vertebral compression fracture. ⋯ The present study shows that catastrophizing can contribute to disability only in the acute period after osteoporotic vertebral compression fracture. As the compression fracture heals, however, age is the critical determinant of disability.

Low back pain is among the most common musculoskeletal system disorders. Outcome measures are needed for the measurement of function, to establish a treatment program, and for monitoring the improvement in low back pain. There exist several questionnaires enquiring about function in low back pain. One of these is Japanese Orthopaedic Association Back Pain Evaluation Questionnaire, whose reliability and validity were previously established. Other than the original version of the questionnaire, only its Persian version exists. The present study aims to investigate the cross-cultural adaptation, reliability and validity of the Turkish version of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire. ⋯ Considering all these data, it was concluded that the Turkish version of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire is valid and reliable.

Multicenter Study
Influence of living environments and working status on low back pain for survivors of the Great East Japan Earthquake.
The Great East Japan Earthquake and devastating Tsunami caused irreparable damage on the northeastern coast of Japan. This study aimed to examine the influencing factors of "Living environment" and "Working status" on low back pain for the survivors of the earthquake evaluated by a self-report questionnaire. ⋯ Though living environment has little effect, "Decrease in income" and "The same occupation as before the earthquake" have strong influences on low back pain.

The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) was developed to resolve problems associated with the original evaluation of cervical myelopathic patients. The aim of this study was to translate the JOACMEQ into Thai as per international recommendations, and to test its reliability and validity in the Thai context ⋯ The Thai version of the JOACMEQ had satisfactory internal consistency and test-retest reliability: it also had good construct validity. It can therefore be used as a reliable tool for assessing quality of life for cervical myelopathy patients in Thailand.

Tranexamic acid (TXA) has proven its efficacy in reducing blood loss and the need for blood transfusions in patients who have undergone a total knee arthroplasty (TKA) surgical procedure. However, no study has investigated the benefits of TXA in unicompartmental knee arthroplasty (UKA), especially, in regard to minimally invasive surgery (MIS) UKA. The purpose of this study is to attempt to prove the benefits of TXA and to identify the risks for blood loss and need for blood transfusions in MIS UKA. ⋯ Based on the study results, we suggest that the use of TXA for patients who undergo MIS UKA do not show benefits in the reduction of blood loss. There were no predictors for the risk of blood loss determined in MIS UKA.
