Translation, adaptation and validation of the Moroccan version of the Quebec Back Pain Disability Scale.
This study aims to translate and cross-culturally adapt the Moroccan version of the Quebec Back Pain Disability Scale (QDS) and to investigate its reliability and validity in Moroccan patients with low back pain (LBP). The translation and cross-cultural adaptation of the QDS were developed in agreement with published guidelines. The QDS was translated by use of the forward and backward translation procedure. ⋯ The correlation between QDS and RMDQ was very good (r = 0.664; p ≤ 0.001). There was no correlation between QDS and the other variables. Accordingly, the Moroccan version of QDS has good reproducibility, internal consistency and validity for the assessment of disability in Moroccan-speaking patients with LBP.

The purpose of this study was to determine the intermediate clinical and radiographic outcomes of Bryan Cervical Disc (Medtronic Sofamor Danek, Inc, Memphis, Tennessee) replacement for the treatment of cervical degenerative disk disease and its effect on adjacent levels. Between November 2004 and December 2007, thirty-four patients (38 disks) underwent Bryan Cervical Disc replacement in the authors' hospital. The authors retrospectively analyzed the records of 32 patients who completed follow-up. ⋯ Prosthesis-related complications were rare, and no reoperations were performed. Bryan Cervical Disc replacement achieves satisfactory mid-term clinical and radiographic outcomes. The authors observed the progression of adjacent segment degeneration postoperatively, although no degradation of clinical outcomes occurred.
