Randomized Controlled Trial Comparative Study
Foraminal stenosis and single-level degenerative disc disease: a randomized controlled trial comparing decompression with decompression and instrumented fusion.
A randomized controlled trial with 5-year outcome data. ⋯ The results are encouraging in that almost all patients had improved by 5 years. However, it is a concern that no significant additional benefit has been noted from the more complex surgery. This suggests that patients are optimally treated by decompression alone, with the proviso that further operations may be required.

Comparative Study Clinical Trial
Outcome evaluation of surgical and nonsurgical management of lumbar disc protrusion causing radiculopathy.
Prospective cohort study. ⋯ HRQOL after LDPR, as measured in this study by NASS NSS, demonstrated similar improvement in both groups and was not meaningfully associated with the treatment received, within the timeframe of this study. At follow-up, all outcome measures remained lower than population normative scores, suggesting that, irrespective of treatment, an element of disability remained.

Cross-cultural adaptation and cross-sectional psychometric testing. ⋯ The Moroccan version of the RMDQ has good comprehensibility internal consistency, reliability, and validity for the evaluation of Moroccan-speaking patients with LBP.

A prospective single-cohort study of 31 patients surgically treated for pelvic injuries with displaced sacral fractures. ⋯ Although the majority of patients achieved independent living, medium-term follow-up indicated significant residual disability. The complex nature of these fractures and the associated injuries should be considered in the rehabilitation of these patients.

Comparative Study
Biomechanical in vitro testing of human osteoporotic lumbar vertebrae following prophylactic kyphoplasty with different candidate materials.
Biomechanical study of human osteoporotic lumbar vertebrae following prophylactic kyphoplasty. ⋯ This study demonstrated that calcium phosphate cements displayed identical behavior to PMMA cement with respect to in vitro mechanical qualities. Consequently, from a mechanical viewpoint, calcium phosphate cements may be used in addition to PMMA cement for kyphoplasty and prophylactic kyphoplasty. Silicon derivatives are apparently not recommendable as candidate materials for kyphoplasty.
