Kyphoplasty has become a standard procedure in the treatment of painful osteoporotic compression fractures. According to current guidelines, involvement of the posterior wall of the vertebral body is a relative contraindication. From February 2002 until January 2008, 97 patients with at least one AO classification A 3.1 fracture were treated by kyphoplasty. ⋯ All patients with cement extravasation, however, were clinically unremarkable. Using the visual analog scale, patients stated that prior to surgery their pain averaged 8.1, whereas after surgery it significantly decreased and averaged 1.6 (p < 0.001). In geriatric patients with osteoporotic vertebral fractures with partial inclusion of the posterior wall of the vertebral body, kyphoplasty is an effective procedure with few complications.

Review Meta Analysis
Transforaminal endoscopic surgery for lumbar stenosis: a systematic review.
Transforaminal endoscopic techniques have become increasingly popular in surgery of patients with lumbar stenosis. The literature has not yet been systematically reviewed. A comprehensive systematic literature review up to November 2009 to assess the effectiveness of transforaminal endoscopic surgery in patients with symptomatic lumbar stenosis was made. ⋯ The reported re-operation rate varied from 0 to 20%. At present, there is no valid evidence from randomized controlled trials on the effectiveness of transforaminal endoscopic surgery for lumbar stenosis. Randomized controlled trials comparing transforaminal endoscopic surgery with other surgical techniques are direly needed.

Multicenter Study Clinical Trial
Bioceramic vertebral augmentation with a calcium sulphate/hydroxyapatite composite (Cerament SpineSupport): in vertebral compression fractures due to osteoporosis.
A prospective, non-randomized multicenter study was initiated to study efficacy and safety of a partly resorbable composite of calcium sulphate and hydroxyapatite (Cerament SpineSupport), a novel, injectable bioceramic, in osteoporotic patients with vertebral compression fractures during 18-month follow-up. Fifteen patients with low-energy trauma and 1-2 vertebral compression fractures verified by magnetic resonance imaging were recruited to undergo percutaneous bioceramic vertebral augmentation under fluoroscopy. The patients were treated with a highly flowable bioceramic containing calcium sulphate, hydroxyapatite and the non-ionic radiocontrast agent iohexol, with final setting time within 1 h. ⋯ There was a statistically significant improvement of physical components in the QoL assessment. No extra-vertebral leakage or neurological deficits were reported in this series. This first prospective multicenter study on a partly resorbable bioceramic material indicate that fracture healing can be achieved with sustained pain relief over a follow-up period of 18 months in an osteoporotic patient population with vertebral compression fractures.

Ineffective erythropoiesis in patients with thalassemia intermedia drives extramedullary hematopoietic tumor formation in several parts of the body. Paraspinal involvement has received increasing attention due to the associated morbidity secondary to spinal cord compression. Although the history and physical examination may help narrow the differential diagnosis, radiographic imaging remains essential to confirm the existence of hematopoietic tissue. ⋯ Several treatment options have been described, including transfusion therapy, laminectomy, radiotherapy, and the use of fetal hemoglobin inducing agents that decrease the hematopoietic drive. However, the ideal management scheme remains controversial. Until large prospective trials evaluate the efficacy and safety of the available treatment options, both in single and in combination therapy, an individualized approach should be entertained.
