Randomized Controlled Trial
The positive effect of posterolateral lumbar spinal fusion is preserved at long-term follow-up: a RCT with 11-13 year follow-up.
Few studies have investigated the long-term effect of posterolateral lumbar spinal fusion on functional outcome. ⋯ Improvement in functional outcome is preserved for 10 or more years after posterolateral lumbar spinal fusion. No difference between instrumented fusion and non-instrumented fusion was observed. Patients who have to retired due to low back pain have the smallest improvement.

A prospective cohort study of skeletally immature idiopathic scoliotic patients treated with the TriaC brace. To determine if the TriaC brace is effective in preventing curve progression in immature adolescent idiopathic scoliotic patients with a very high risk of curve progression based on reported natural history data. The aim of the newly introduced TriaC brace is to reverse the pathologic transverse force pattern by externally applied and continuously present orthotic forces. ⋯ The current study demonstrates that treatment with the TriaC brace reduces the scoliosis, and that the achieved correction is maintained in some degree after skeletal maturity is reached and bracing is discontinued. It also prevents further progression of the Cobb angle in idiopathic scoliosis. The new brace does not differ from the conventional braces as far as maintaining the deformity is concerned.

To study the effect of the degree of scoliosis, degree of hypokyphosis/lordosis and rotation of apical vertebra on individual lung volume (measured with CT scan) in asymptomatic adolescent idiopathic scoliosis (AIS) patients. Individual (right and left) lung volume, angle of kyphosis and rotation of apical vertebra, were measured in 77 asymptomatic AIS patients having right thoracic curve, using modern computed tomography (CT) scan. To compare, lung volumes were measured in 22 normal persons (control group). ⋯ A significant inverse correlation was found between the angle of kyphosis and right to left lung volume ratio, i.e., as the angle of kyphosis decreased the convex to concave lung volume ratio increased (P = 0.0109, r = -0.255). In asymptomatic, AIS patients, with increase in degree of curvature, and rotation of apical vertebra, the ratio of convex to concave side lung volume increases; indicating concave side lung volume is comparatively more affected (decreased) than convex side lung volume. On the other hand with decrease in the angle of kyphosis the convex to concave lung volume ratio increases indicating kyphotic angle has an inverse relation to convex to concave lung volume ratio.

Over the last couple of years the European Spine Journal has become truly international with papers from all over the world, and at the same time it has increased its size. Professor Mulholland has selected and reviewed some 40 papers from over 200 published in 2007 and that he felt were of particular interest to practicing surgeons and would influence their management of patients, or papers that challenged established beliefs. Papers dealing with back pain, spondylolysis, tumors, spinal stenosis, spinal infection, clinical examination, lumbar disc herniation, spinal fractures, etc. are reviewed and their significance assessed. The aim of the review is to encourage readers to read the papers themselves, hopefully stimulated by the trenchant comments of the reviewer, both critical and laudatory.

The purpose of our prospective study is to evaluate the surgical outcome among patients aged 80 years and above, who underwent surgery for lumbar spinal stenosis. We assessed patients' clinical and demographic data, procedures, perioperative complications, preoperative and postoperative pain intensity, basic activities of daily living (BADL), patients' satisfaction, the need for repeated surgery, and overall mortality. Thirty-nine patients more than 80 years of age were operated in our institution in the last decade. ⋯ No operative or perioperative mortality was noticed and the overall hospital stay for these elderly patients was 3.6 days on average. Surgery in very old elderly patients is safe and effective in the treatment of spinal stenosis, who did not respond well to the conservative treatment. The surgery did not increase the associated morbidity and mortality and most of the patients benefited from the surgery in terms of reduction in pain, increase in ADL and walking ability and overall increase in the satisfaction rate.
