Case Reports Comparative Study
New technique in congenital scoliosis involving fixation to the pelvis after hemivertebra excision.
The authors conducted a retrospective study involving description of a new surgical technique. ⋯ This prospective study demonstrates a successful surgical technique for spinal stabilization after congenital hemivertebra excision in infants and young children with relatively small and soft bones when standard constructs like pedicle screws may not be optimal devices. Coronal and sagittal balance (restoration with improvement of lordosis) was successfully achieved in all cases.

This is a retrospective review on the application of the authors' technique of atlantoaxial lateral mass plate and screw fixation on a rare subset of patients having mobile and reducible atlantoaxial subluxation in the presence of occipitalized atlas. ⋯ Although lateral mass plate and screw fixation in the presence of occipitalized atlas is technically a relatively difficult and anatomically a precise surgical procedure, the firm and segmental stabilization that it provides offers an optimum situation for bony fusion.

This is a case report. ⋯ Epidural emphysema secondary to traumatic pneumomediastinum is benign and self-limiting. However, the life-threatening causes should be considered and ruled out.

Randomized Controlled Trial Comparative Study Clinical Trial
Effectiveness of salmon calcitonin nasal spray in the treatment of lumbar canal stenosis: a double-blind, randomized, placebo-controlled, parallel group trial.
Double-blind, randomized, placebo-controlled study to assess the effectiveness of calcitonin nasal spray on symptoms and function in patients with lumbar canal stenosis. ⋯ In this first ever largest randomized placebo-controlled parallel group trial of nasal calcitonin in spinal stenosis, nasal calcitonin was not superior to placebo in treating the symptoms of spinal stenosis at 6 weeks. Based on this study, nasal calcitonin does not appear to have a role in nonoperative treatment of lumbar canal stenosis.

Multicenter Study
Sensitivity and specificity of outcome measures in patients with neck pain: detecting clinically significant improvement.
Prospective, single-cohort study. ⋯ The present findings will assist in the choice of outcome measures in trials on neck pain. The study also illustrates a methodologic framework for interpreting change scores in terms of clinical improvement, facilitating the process of making sense of research data in the clinical setting.
