Randomized Controlled Trial
The use of curare during anesthesia to prevent iatrogenic muscle damage caused by lumbar spinal surgery through a posterior approach.
Prospective randomized study of patients undergoing lumbar arthrodesis. ⋯ The use of curare during anesthesia did not limit the muscle damage caused by surgery.

Controlled Clinical Trial
Postural changes of the dural sac in the lumbar spines of asymptomatic individuals using positional stand-up magnetic resonance imaging.
Positional magnetic resonance imaging (MRI) study of control subjects. ⋯ A significant posture-dependent difference of the dural sac cross-sectional area at the level of intervertebral disc in asymptomatic volunteers has been demonstrated. When the posture changed from supine to standing position, lumbar dural sac volume expanded by the increased pressure of cerebrospinal fluid, and the dural sac cross-sectional area increased. The smallest values were found in the supine position.

Translation, revision, back-translation, and 3-way validity were performed. ⋯ The data showed that the cultural adaptation process was successful and that the adapted instrument demonstrated having excellent psychometric properties, reliable in the Brazilian culture.

Surgeons attending a Cervical Spine Research Society (CSRS) meeting were surveyed about the surgical approach to cervical spondylotic myelopathy (CSM). ⋯ These results measure surgeons' opinions on the suitability of cases for randomization and help to define entry and exclusion criteria for a RCT comparing ventral to dorsal strategies. Over 50% of CSM cases from a general spinal practice might be eligible for randomization.

Comparative Study
Posterior spinal fusion for scoliosis in duchenne muscular dystrophy diminishes the rate of respiratory decline.
To assess the rate of decline in pulmonary function in Duchenne muscular dystrophy (DMD) before and after posterior spinal fusion for scoliosis. ⋯ Posterior spinal fusion for scoliosis in DMD is associated with a significant decrease in the rate of respiratory decline postsurgery compared with presurgery rates.
