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
Responsiveness of pain and disability measures for chronic whiplash.
Cohort study. ⋯ Pain bothersomeness and the Patient Specific Functional Scale provide the most responsive measures of pain and disability, respectively, in patients with chronic whiplash.

Comparative Study
Comparison of one-level posterior lumbar interbody fusion performed with a minimally invasive approach or a traditional open approach.
Prospective cohort study. ⋯ The present study, which was based on the authors' initial experience with the minimally invasive approach, could confirm favorable results reported by previous uncontrolled cohort studies in the aspects of less blood loss, less transfusion need, less postoperative back pain, quicker recovery, and shorter hospital stay. It also showed the similar surgical efficacy of the minimally invasive approach with that of the traditional open technique. However, the minimally invasive technique needs longer surgical time and a prudent attention to lower the risk of technical complications. Further long-term, prospective studies involving a larger study group are needed to determine the benefits of this minimally invasive percutaneous procedure.

This study clarifies the correlation between the components of the Scoliosis Research Society Outcomes Instrument (SRS-24) and the radiographic parameters after surgery in Japanese idiopathic scoliosis patients. ⋯ Patients with a greater Cobb angle or rotation angle in the thoracic curve had a negative self-image. Self-image improved after surgery by greater correction of the thoracic Cobb angle. Thoracic scoliotic deformity with prominence should be substantially reduced by the surgical treatment to improve satisfaction rates and self-image regarding back appearance. Additionally, physicians should pay more attention to patients' concern regarding their postoperative scars to obtain better outcomes.

Case Reports
Comparison of thoracic pedicle screw to hook instrumentation for the treatment of adult spinal deformity.
Retrospective, case-control, matched cohort. ⋯ TPS instrumentation allows greater coronal and sagittal plane correction and may reduce the risk of thoracic pseudarthrosis compared with hook constructs when treating adult spinal deformities.
