Comparative StudyLess incidence of coronary artery disease in general anesthesia compared to spinal-epidural anesthesia after total knee replacement: 90-day follow-up period by a population-based dataset.
Total knee replacement (TKR) is an effective and safe procedure. However, large-scale study to compare the incidence of coronary artery disease (CAD) after spinal or epidural anesthesia (SA-EA) or general anesthesia (GA) for TKR has not ever been conducted. To do so, we studied a population-based dataset from the Taiwan National Health Research Institute and hypothesized that the incidence of CAD might be different with regional than with general anesthesia. ⋯ The Kaplan-Meier survival analysis of IHD-free cumulative survival rate during the 90-day follow-up period for patients who underwent TKR was significantly lower in group 1 than in group 2. The hazard ratio for the occurrence of CAD was 2.80 (95 % CI 1.16-6.78), and the hazard was higher for patients who received SA-EA than for patients who received GA after adjusted potential confounding factors. After the performance of TKR, patients had a potentially increased risk for CAD in SA-EA compared to GA during the 90-day follow-up period.

Two-level anterior cervical discectomy and fusion using self-locking stand-alone polyetheretherketone cages with two anchoring clips placed in the upper and lower vertebrae, respectively.
Anterior cervical discectomy and fusion (ACDF) is a widely accepted surgical procedure for the treatment of cervical degenerative disk diseases (CDDD). The purpose of our study was to investigate the reliability and efficacy of ACDF using self-locking stand-alone polyetheretherketone (PEEK) cages, with two anchoring clips placed in the upper and lower vertebrae, respectively. ⋯ ACDF using a self-locking stand-alone PEEK cage with two anchoring clips placed in the upper and lower vertebrae, respectively, could be considered a safe and effective substitute for fusion in patients with two-level CDDD; it can effectively restore the intervertebral height, facilitate radiologic follow-up, cause few complications, and lead to satisfactory outcomes.

Relevance of using a compressive preload in the cervical spine: an experimental and numerical simulating investigation.
Simulating compressive action of muscles, a follower load attends to reproduce a more physiological biomechanical behaviour of the cervical spine. Only few experimental studies reported its influence on kinematics and intradiscal pressure in the cervical spine. ⋯ Although the follower load represents an attractive option to apply compressive preload during experimental tests, we found that this method could affect the native biomechanical behaviour of spine specimen depending on which movement was considered. Only minimal effects were observed in FE, whereas significant changes in kinematics and intradiscal pressures were observed for AR and LB.

Comparative StudyIs it possible to eliminate the plate-related problems and still achieve satisfactory outcome after multilevel anterior cervical discectomy?
Stand-alone cage-assisted anterior cervical discectomy and fusion (ACDF) has proved to be safe and effective procedure for treatment of mono-segmental cervical degenerative stenosis (CDS). However, the success rate has reported to decline as the number of levels increases. The aim of this prospective study was to evaluate the short-term results of multilevel ACDF using stand-alone polyetheretherketone (PEEK) cages. ⋯ With proper patient selection, meticulous surgical technique and strict post-operative cervical bracing, the less-invasive indirect anterior cervical decompression technique augmented with stand-alone PEEK cage-assisted ACDF is an efficient and safe method for the treatment of multilevel CDS.
