We report a pediatric baseball player having both a fracture of the posterior ring apophysis and spondylolysis. He was presented to a primary care physician complaining of back pain and leg pain. Despite conservative treatment for 3 months, the pain did not subside.

Minimally invasive and simultaneous removal of herniated intracanal and extracanal lumbar nucleus pulposus with a percutaneous spinal endoscope.

Herniated nucleus pulposus (HNP) in the lumbar spine is usually found in the neural canal (in the intracanal space) and occasionally in the extracanal space, where it is known as a lateral HNP. HNP is rarely found simultaneously in both spaces. However, we experienced such a case in a 48-year-old man who presented with right leg pain and lower back pain that had lasted for more than a year.

Indications for surgery in intestinal Behçet's disease.

Background/aims: As advances in steroids and immunosuppressants made medical treatment first-line therapy for Behçet's disease, the criteria for elective surgery became unclear. The aim of this paper is to establish surgical criteria for Behçet's.

Methodology: We reviewed the medical records of 8 consecutive Japanese patients who were diagnosed with intestinal Behçet's at Tsukuba University Hospital between 1976 and 2001.
