Spinal posture and the resultant changes during the entire pubertal growth period have not been reported previously. No cohort study has focused on the development of spinal posture during both the ascending and the descending phase of peak growth of the spine. The growth and development of a population-based cohort of 1060 children was followed up for a period of 11 years. ⋯ Women were more lordotic at all ages. Thoracic hyperkyphosis of > or =45 degrees was as prevalent in boys as girls at 14 years, but significantly (P<0.0001) more prevalent in men (9.6%) than in women (0.9%) at 22 years. The degree of mean thoracic kyphosis and the prevalence of hyperkyphosis increased in men during the descending phase of peak growth of the spine, but decreased in women.

Case Reports
Seventh cervical vertebral body solitary osteochondroma. Report of a case and review of the literature.
Solitary osteochondroma of the cervical spine is a rare manifestation of a common bony tumour. It can create symptoms, depending on the adjacent compressed structures. In this report, a patient suffering solitary osteochondroma on the anterolateral aspect of the C7 vertebral body is presented and the literature is reviewed. ⋯ At the cervical spine, they can cause neurological symptoms and more rarely, dysphagia. Reviewing the literature, no case of solitary osteochondroma located in the anterior aspect of the C7 body was found. Two cases suffering from dysphagia were reported due to external compression by anterior hyperostosis of the cervical spine, but not due to osteochondroma.

Multicenter Study Clinical Trial
A 2-year follow-up pilot study evaluating the safety and efficacy of op-1 putty (rhbmp-7) as an adjunct to iliac crest autograft in posterolateral lumbar fusions.
The ability of bone morphogenetic proteins (BMPs) to induce bone formation has led to a multitude of investigations into their use as bone graft substitutes in spinal surgery. The purpose of this multi-center clinical pilot study was to evaluate the safety and efficacy of BMP-7 (osteogenic protein 1, OP-1), in the form of a putty, combined with autograft for intertransverse process fusion of the lumbar spine in patients with symptomatic spinal stenosis and degenerative spondylolisthesis following spinal decompression. Twelve patients with spinal stenosis and degenerative lumbar spondylolisthesis underwent a laminectomy and partial or complete medial facetectomy as required for decompression of the neural elements, followed by an intertransverse process fusion by placing iliac crest autograft and OP-1 putty between the decorticated transverse processes. ⋯ A successful fusion was observed in slightly over half the patients in this study, using stringent criteria without adjunctive spinal instrumentation. This study did not demonstrate the statistical superiority of OP-1 combined with autograft over an autograft alone historical control, in which the fusion rate was 45%. There were no adverse events related to the OP-1 putty implant in this study, which supports findings in other studies suggesting the safety of bone morphogenetic proteins in spinal surgery.

Review Case Reports
Tuberculous sacroiliitis. A case report and review of the literature.
Infections of the musculoskeletal system are tuberculous in nature in 1-5% of cases. The sacroiliac joint is involved in 3-9.7%. We describe the case of a 32-year-old man with tuberculous sacroiliitis presented as a growing mass on the lateral aspect of his right proximal and mid-thigh. Open biopsy, histology, cultures and PCR established the diagnosis of tuberculosis. ⋯ After surgical drainage of the abscess, the patient was administrated a triple antibiotic regimen for 12 months. Seven years postoperatively, the patient is disease-free with no functional limitation. This case report highlights the importance of continued awareness for early detection and treatment of a tuberculous sacroiliac joint infection.

Randomized Controlled Trial
Single-blinded prospective randomized study comparing open versus needle technique for obtaining autologous cancellous bone from the iliac crest.
One of the most frequent complications of cervical anterior discectomy with fusion is pain at the donor site, usually the iliac crest. Despite the advent of new materials, autologous bone is still the "gold standard" for fusion procedures. A prospective, single blinded, randomized study was performed to evaluate the effect of a minimal invasive technique to obtain autologous bone from the iliac crest on pain. ⋯ Obtaining autologous cancellous bone through a large needle for filling a cervical cage (even multiple cages) is safe and evidently less painful than through a classical open procedure. If pain exists it does not last very long. Generally, the pain is resolved within 2 weeks.
