Comparative study. ⋯ Both small and large PE particles are present after TDR revision surgery compatible with both THA and TKA wear patterns. The similarities between periprosthetic tissue reactions in the different groups may give more insight into the clinical relevance of PE particles and inflammatory cells in the lumbar spine. The current findings may help to improve TDR design as applied from technologies previously developed in THA and TKA with the goal of a longer survival of TDR.

Review Meta Analysis
Evaluation of treatment effectiveness for the herniated cervical disc: a systematic review.
Systematic review. ⋯ No evidence for effectiveness of conservative treatment compared with surgery was found. Although there is moderate evidence for the effectiveness of some surgical interventions, no unequivocal evidence for the superiority of 1 particular surgical treatment was found. Worldwide, most patients receive supplementary implants; however, cervical discectomy without graft may be preferred because of similar outcomes, lower costs, and possibly a lower risk of adjacent-level disease. More high-quality RCTs using validated outcome measures (including adjacent level disease) are needed.

An anatomic study of anterior cervical dissection of 11 embalmed cadavers. ⋯ This study found that superior to C7-T1, both RLNs had similar anatomic courses and received similar protection via surrounding soft-tissue structures. From an anatomic perspective, the authors did not appreciate a side-to-side difference superior to this level that could place either nerve under greater risk for injury.

Human cadaveric study. ⋯ Intraoperative O-arm images accurately detect significant pedicle screw violations in the thoracic and lumbosacral spine but are less accurate for the cervical spine.

Multicenter Study Clinical Trial
Relationship between preoperative expectations, satisfaction, and functional outcomes in patients undergoing lumbar and cervical spine surgery: a multicenter study.
Analysis of prospectively collected multicenter data. ⋯ This study showed that more than functional outcomes matter; preoperative expectations and fulfillment of expectations influence postoperative satisfaction in patients undergoing lumbar and cervical spine surgery. This underlines the importance of taking preoperative expectations into account to obtain an informed choice on the basis of the patient's preferences.
