Randomized Controlled Trial Multicenter Study Comparative Study
Evaluation of spinal kinematics following lumbar total disc replacement and circumferential fusion using in vivo fluoroscopy.
In vivo fluoroscopic analysis of lumbar spinal motion with total disc replacement (TDR), fusions, and controls. ⋯ TDR produces physiologic lumbar spinal motion profiles in flexion and extension at the operative and proximal adjacent levels. Fusions, however, produced steeper motion gradients at the proximal adjacent level, while undergoing significantly greater sagittal plane translation during flexion-extension.

Multicenter Study Comparative Study
Outcomes of surgical treatment in male versus female adolescent idiopathic scoliosis patients.
This research was part of a multicenter study of the surgical treatment of adolescent idiopathic scoliosis (AIS). ⋯ Male AIS patients had slightly more rigid primary curves compared to females but a similar degree of postoperative scoliosis correction. Differences in the preoperative status and perioperative course did not compromise the outcomes of surgical treatment as in all other measures; the results were comparable between the genders.

Multicenter Study
Psychosocial variables in patients with (sub)acute low back pain: an inception cohort in primary care physical therapy in The Netherlands.
A prospective cohort study of patients with episodes of acute or subacute low back pain, seeking physical therapy in primary care, with follow-up at weeks 2, 4, 8, and 12. ⋯ The study strongly revealed pain-related items to be essential factors in the development of chronicity and long-term disability in primary care physical therapy. Health status at 8 weeks seems crucial in developing chronicity.

Multicenter Study Comparative Study
Thoracoscopic scoliosis surgery affects pulmonary function less than thoracotomy at 2 years postsurgery.
Prospective evaluation of pulmonary function before and 2 years after surgery following anterior scoliosis instrumentation. ⋯ This study shows a clear advantage to the minimally invasive thoracoscopic approach with regards to pulmonary function when compared with the open thoracotomy approaches.

Randomized Controlled Trial Multicenter Study Comparative Study
Multidisciplinary rehabilitation for subacute low back pain: graded activity or workplace intervention or both? A randomized controlled trial.
Population-based randomized controlled trial. ⋯ Workplace intervention is advised for multidisciplinary rehabilitation of subacute LBP. Graded activity or combined intervention is not advised.
