Multicenter Study
Validity of the Spanish version of the Scoliosis Research Society-22 (SRS-22) Patient Questionnaire.
A cross-sectional multicenter study was performed to validate the Spanish version of the Scoliosis Research Society-22 (SRS-22) Patient Questionnaire. ⋯ The Spanish version of the SRS-22 is valid. It has a factorial structure similar to that of the original questionnaire. Moreover, it relates to known severity characteristics of the disease, distinguishes among scoliosis patient groups, and shows concordant values with another valid instrument for measuring self-perceived health.

Retrospective outcome measurement after circumferential reconstructive surgery with lumbar fusion in patients with chronic discogenic low back pain. ⋯ When using strict patient selection criteria that include independent determination of pain generators via pressure-controlled diskography and completion of a preoperative conditioning program for improving general health status, the number of levels in reconstructive lumbar surgery may not significantly impact overall clinical outcome.

A retrospective review was performed on 21 adult patients surgically treated with high-grade spondylolisthesis (Grade III, IV, or V). Additionally, the natural history, classification, and surgical alternatives for high-grade spondylolisthesis in the adult are discussed through literature review. ⋯ Adult patients with high-grade spondylolisthesis not responding to nonoperative treatment can be stabilized in situ with posterior instrumentation from L4 to S1. The use of adjunctive fixation with iliac screws and/or transvertebral screws is recommended for the adult patient, particularly in revision or unstable cases. Reduction of the slipped vertebrae remains controversial for all grades of spondylolisthesis and more so for the adult patient. Partial reduction of the slip angle, decreasing the lumbosacral kyphosis, should be considered if significant sagittal malalignment is present or to improve arthrodesis success. Anterior column support should be performed, particularly when reduction has been obtained. Anterior column support can be performed, anteriorly or posteriorly, either by using inter vertebral body structural strut support or with a transsacral fibular dowel to improve stability and success of arthrodesis.

Randomized Controlled Trial Multicenter Study
Implementation of the Dutch low back pain guideline for general practitioners: a cluster randomized controlled trial.
Cluster randomized controlled trial for a multifaceted implementation strategy. ⋯ The multifaceted intervention strategy modestly improved implementation (for parts of the recommendations in) the Dutch low back pain guideline by general practitioners and produced small concomitant changes in patient management. The implementation strategy produced fewer referrals to therapists during follow-up consultations.

Systematic review. ⋯ NRT appears to be a safe and effective intervention for nonspecific LBP. This conclusion is limited to three trials conducted by a small number of experienced clinicians. Further trials in other settings are needed to determine whether these favorable results can be generalized.
