Clinical Trial
Assessment of spinal flexibility in adolescent idiopathic scoliosis: suspension versus side-bending radiography.
Prospective evaluation of a new suspension test to determine curve flexibility in adolescent idiopathic scoliosis (AIS) in comparison with erect side-bending. ⋯ Results of this study demonstrate the feasibility to really evaluate the spine flexibility with the suspension test. The estimated flexibility values are realistic and similar to those reported in vitro. Suspension should be used in the future for spine flexibility assessment.

Randomized Controlled Trial Comparative Study
Cervical disc replacement in patients with and without previous adjacent level fusion surgery: a prospective study.
Prospective 6-center study. OBJECTIVE.: To evaluate outcomes of cervical disc replacement performed adjacent to a prior cervical fusion. ⋯ Although the level adjacent to a prior cervical fusion is subject to increased biomechanical forces, potentially leading to a higher risk of failure, the PCM disc was well tolerated in the short term. The early clinical results of disc replacement adjacent to a prior fusion are good and comparable to the outcomes after primary disc replacement surgery. However, in view of the small study population and short-term follow-up, continued study is mandatory.

Comparative Study Clinical Trial
Significantly improved outcomes with a less invasive posterior lumbar interbody fusion incorporating total facetectomy.
Original study. ⋯ Clinical outcomes were significantly improved after both ST-PLIF and LI-PLIF. However, outcomes were significantly better after LI-PLIF than after ST-PLIF. Significantly shortened hospital stay with LI-PLIF probably reflected the "less invasive" technique per se. Significantly better clinical outcomes with fewer complications after LI-PLIF, however, potentially reflected maneuvers singular to LI-PLIF: (1) preservation of posterior elements, (2) avoidance of far lateral dissection over the transverse processes, (3) bilateral total facetectomy, (4) fewer neurologic complications, and (5) avoidance of iliac crest autograft. LI-PLIF is therefore recommended over ST-PLIF.

A reliability and validity study of a translated, culturally adapted questionnaire. ⋯ The results of our study show that QDS as a functional status questionnaire has been translated into Turkish without losing the psychometric properties of the original version. The Turkish version of the QDS has good comprehensibility, internal consistency, and validity and is an adequate and useful instrument for the evaluation of disability in patients with LBP.

Case Reports Clinical Trial
Limaprost alfadex improves myelopathy symptoms in patients with cervical spinal canal stenosis.
Myelopathy symptoms were prospectively studied in patients with cervical spinal canal stenosis (CSCS), using objective grading systems and stabilometry, to examine the effect of administration of prostaglandin E1 derivative limaprost alfadex (limaprost). ⋯ The efficacy of oral limaprost administration for patients with CSCS was confirmed by objective scoring and quantitative data.
