Disturbance of rib cage development causes progressive thoracic scoliosis: the creation of a nonsurgical structural scoliosis model in mice.
The pathomechanism underlying idiopathic scoliosis remains unclear, and, to our knowledge, a consistent and relevant animal model has not been established previously. The goal of this study was to examine whether a disturbance of rib cage development is a causative factor for scoliosis and to establish a nonsurgical mouse model of progressive scoliosis. ⋯ We established a nonsurgical experimental model of progressive scoliosis and also demonstrated that a rib cage deformity with an imbalanced load to the vertebral body resulted in progressive structural scoliosis.

Multicenter StudyA clinical prediction model to determine outcomes in patients with cervical spondylotic myelopathy undergoing surgical treatment: data from the prospective, multi-center AOSpine North America study.
Cervical spondylotic myelopathy is a progressive spine disease and the most common cause of spinal cord dysfunction worldwide. The objective of this study was to develop a prediction model, based on data from a prospective multi-center study, relating a combination of clinical and imaging variables to surgical outcome in patients with cervical spondylotic myelopathy. ⋯ On the basis of the results of the AOSpine North America study, we identified a list of the most important predictors of surgical outcome for cervical spondylotic myelopathy.

Patient-reported outcome after displaced femoral neck fracture: a national survey of 4467 patients.
Arthroplasty appears to be superior to internal fixation, with regard to complication rates, as a treatment for displaced femoral neck fractures. Less is known about the result as perceived by the patient. The aims of this prospective observational study were (1) to determine whether patient-reported outcomes after a displaced femoral neck fracture can be evaluated on a nationwide basis by means of a mailed survey, and (2) to evaluate differences among treatment methods with respect to patient-reported pain, health-related quality of life, and satisfaction with the surgical result. ⋯ A mailed patient-reported outcomes questionnaire is a feasible method for national follow-up of hip fractures, with an acceptable response rate. The study also suggests that total hip arthroplasty as a treatment for femoral neck fracture is associated with less pain and greater satisfaction at short-term follow-up compared with internal fixation and hemiarthroplasty, both in patients younger and older than seventy years.
