Randomized Controlled Trial
Randomized clinical study to compare the accuracy of navigated and non-navigated thoracic pedicle screws in deformity correction surgeries.
Randomized clinical trial (level I evidence). ⋯ Iso-C navigation increases accuracy, and reduces surgical time and radiation in thoracic deformity correction surgeries.
-
Systematic review of randomized controlled trials. ⋯ In the long-term, multidisciplinary back training has a positive effect on work participation in patients with nonspecific chronic low back pain.
-
A prospective nonrandomized, longitudinal cohort study. ⋯ The results indicate the potential of radiosurgery in the treatment of patients with spinal metastases, especially those with solitary sites of spine involvement, to improve long-term palliation.
-
Retrospective cohort study with prospective clinical follow-up. ⋯ In our series, the symptom duration before operation and the speed of onset do not affect the outcome more than 2 years after surgery. Based on the SF-36, ODI, and Low Back Outcome Scores, patients who have had CES do not return to a normal status.

Case Reports
Polyethylene wear debris and long-term clinical failure of the Charité disc prosthesis: a study of 4 patients.
A clinical case series of 4 patients undergoing anterior lumbar revision due to failure of total disc replacement surgery. ⋯ This study demonstrates the clinical significance of polyethylene wear debris and the potential for osteolysis with total disc replacements. The authors recommend that patients undergoing lumbar disc arthroplasty receive long-term follow-up to monitor the wear and functional status of their implants.
