A retrospective study. ⋯ As applied in anterior cervical fusion, the local decompression bone embedded into carbon fiber-reinforced polyetheretherketone cages is enough and can achieve successful fusion, poignant clinical outcomes while achieving no donor site morbidity.
-
Retrospective cross-sectional analysis of administrative data. ⋯ Both the supply of chiropractors and the utilization of chiropractic by older US adults varied widely by region. Increased chiropractic supply was associated with increased chiropractic use but not with increased chiropractic utilization intensity. Utilization of chiropractic care is likely sensitive to both supply and patient preference.

Retrospective cost-effectiveness analysis. ⋯ This cost-effectiveness analysis reports favorable results for ACDF procedures utilizing a tantalum implant. The data reported suggest that using porous tantalum as a stand-alone device is less costly and more effective than autograft and plate in ACDF procedures.
-
Retrospective study. ⋯ Si-CaP is an alternative to autogenous bone graft in spinal arthrodesis procedures. At 12-month follow-up, we detected high levels of bony fusion using Si-CaP in combination with various surgical spinal techniques.

An in vitro biomechanical study on 3-dimensional flexibility of human lumbosacral motion segments after multiple freeze-thaw cycles and cumulative testing. ⋯ The flexibility of the human cadaveric lumbosacral motion segments between test days was significantly affected after repeated freeze-thaw and cumulative testing cycles. Multiple freeze-thaw cycles and cumulative testing, however, does not affect flexibility data for tests carried out within a single test day.
