Retrospective analysis. ⋯ The use of a continuous infusion of bupivacaine provided good analgesia with low pain scores. The significant reduction in basal morphine use may reflect a replacement by bupivacaine, although this is limited by potential treatment bias. Multivariate analysis was required to control for ongoing changes in anesthesia practice over the many years of the study. The optimal depth of catheter placement is unclear from this analysis and should be studied prospectively.

Prospective radiological analysis of patients with achondroplasia. ⋯ Sagittal parameters and possible relationships between sagittal parameters and symptoms were found to be significantly different in achondroplasia patients and normal healthy controls. The present study shows that sagittal spinal and pelvic parameters can assist the treatment of spinal disorders in achondroplasia patients.

Retrospective review of a multicenter database. ⋯ In this review of a large multicenter database of surgically treated pediatric scoliosis, neuromuscular scoliosis had the highest morbidity, but relatively high complication rates occurred in all groups. These data may be useful for preoperative counseling and surgical decision-making in the treatment of pediatric scoliosis.

Evaluation of degenerated intervertebral discs from a rabbit annular puncture model by using specialized magnetic resonance imaging (MRI) techniques, including displacement encoding with stimulated echoes and a fast-spin echo (DENSE-FSE) acquisition and delayed gadolinium-enhanced MRI of cartilage (dGEMRIC). ⋯ Noninvasive and quantitative MRI techniques can be used to evaluate the mechanical and biochemical changes that occur with animal models of disc degeneration. DENSE-FSE, dGEMRIC, and similar techniques have potential for evaluating the progression of disc degeneration and the efficacy of treatments.

Multicenter Study Comparative Study
The morbidity and mortality of fusions from the thoracic spine to the pelvis in the adult population.
A retrospective analysis. ⋯ Complex spine reconstruction involving fusions from the thoracic spine to the pelvis continues to be a high-risk procedure in spite of more advanced surgical and perioperative techniques.
