Surgery for lumbar spondylolisthesis is widely performed. However, there have been no reports comparing posterolateral and anterior interbody fusion prospectively. We compared instrumented posterolateral fusion with anterior interbody fusion for L4 spondylolisthesis in a prospective study. ⋯ If single level fusion for L4 spondylolisthesis is performed, both anterior and posterior methods reduce patients' low back and leg pain. Improvement of low back pain was significantly greater after ALIF; however, periods of hospital stay and of bed rest were significantly longer.

Until recently, no Japanese versions have existed of the more popular, patient-reported disability questionnaires for neck pain. This study aimed to test the reliability, validity, and responsiveness of the Japanese version of the Neck Pain and Disability Scale (NPDS), one of the most widely used questionnaires in patients with neck pain. ⋯ The Japanese version of the NPDS is a useful scale with reliability, validity, and responsiveness in assessing patients suffering from neck pain.

This cross-sectional study was conducted to obtain epidemiologic data on chronic musculoskeletal pain in the Japanese people, and with it a better understanding of the actual conditions and problems involved. ⋯ Chronic musculoskeletal pain does not necessarily improve even with prolonged treatment. It adversely affects daily life and both physical and mental health. Because those suffering pain often increasingly need assistance in daily activities, people around them are also affected. The therapeutic system and treatment procedures for chronic musculoskeletal pain merit prompt review.
