No results on long-term outcome in terms of health-related quality of life (HRQL) have previously been presented for patients treated for adolescent idiopathic scoliosis. A consecutive series of patients with adolescent idiopathic scoliosis, treated between 1968 and 1977 before the age of 21, either with distraction and fusion using Harrington rods [surgical treatment group (ST), n=156; 145 females and 11 males] or with a brace [brace treatment group (BT), n=127; 122 females and 5 males] were followed at least 20 years after completion of the treatment. Ninety-four percent of ST and 91% of BT patients filled in a questionnaire comprising the SF-36, Psychological General Well-Being Index (PGWB), Oswestry Disability Back Pain Questionnaire, parts of SRS/MODEM'S questionnaire and study-specific questions concerning the treatment, as a part of an unbiased personal follow-up examination including radiography and clinical examination. ⋯ No correlation was found between the outcome scores and curve size after treatment, curve type, total treatment time or age at completed treatment. Patients treated for adolescent idiopathic scoliosis were found to have approximately the same HRQL as the general population. A minority of the patients (4%) had a severely decreased psychological well-being, and a few (1.5%) were severely physically disabled due to the back.

High-speed cutters are used in the surgery of the cervical spine. Such high-speed devices can produce an aerosol cloud. As a patient can be a reservoir for pathogens, with aerosol-borne paths of transmission, such an aerosol has to be seen as a potential risk of infection for health care professionals present during the surgery and for patients if micro-organisms are transferred through the medical personnel. ⋯ Such aerosols can be contaminated with pathogens if the patient was infected or colonized. Therefore, sufficient protective measures have to be recommended for everyone present in the operating room during such surgeries. In addition, efficient disinfection of the room and all mobile equipment is necessary after each surgery involving high-speed cutting devices.

Localization and expression of cartilage-derived morphogenetic protein (CDMP)-1 in tissues at the site of ossification of the ligamentum flavum (OLF) were examined by immunohistochemistry and in situ hybridization. The CDMP-1 protein and messenger ribonucleic acid (mRNA) were localized in spindle-shaped cells and chondrocytes in the OLF tissues. ⋯ These data indicate that CDMP-1 is locally activated and localized in spindle-shaped cells and chondrocytes at the site of OLE. Given the previously reported promoting action of CDMP-1 for chondrogenesis, the current results suggest that CDMP-1 may be involved in the progression of OLF, leading to the narrowing of spinal canal and thus causing severe clinical manifestations.
