Adjacent segment degeneration after lumbar dynamic stabilization using pedicle screws and a nitinol spring rod system with 2-year minimum follow-up.
Prospective study evaluating the adjacent segment degeneration after lumbar dynamic stabilization using pedicle screws and a Nitinol spring rod system. ⋯ According to our results, lumbar dynamic stabilization using pedicle screws and a Nitinol spring rod system may not prevent adjacent level degeneration completely.

Should 25-hydroxyvitamin D and bone density using DXA be tested in adolescents with lumbar stress fractures of the pars interarticularis?
Retrospective study. ⋯ On the basis of these data, we recommend routine vitamin D testing and do not recommend routine DXA in adolescents with lumbar stress fractures of the pars interarticularis.

Comparative StudyComparison of a fluoroscopic 3-dimensional imaging system and conventional CT in detection of pars fractures in the cadaveric lumbar spine.
Cadaveric Study. ⋯ Three-dimensional fluoroscopic imaging provides comparable diagnostic imaging with CT scan in an experimental cadaveric model of spondylolysis using up to 85% less radiation than conventional CT scan.

Comparative StudyWould an anatomically shaped lumbar interbody cage provide better stability? An in vitro cadaveric biomechanical evaluation.
A biomechanical cadaveric study of lumbar spine segments. ⋯ The parallel-shaped and anatomically shaped I/F cages provided similar stability in a PLIF construct. The greater stability of the TLIF construct was likely due to a more anterior placement of the TLIF cage and preservation of the contralateral facet joint.
