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.

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.

Does the lower instrumented vertebra have an effect on lumbar mobility, subjective perception of trunk flexibility, and quality of life in patients with idiopathic scoliosis treated by spinal fusion?
Cross-sectional study in patients with idiopathic scoliosis treated with spinal fusion. ⋯ LIV correlated moderately with lumbar mobility, health-related quality of life (SRS-22), and spinal pain (SRS-22 pain subscale), but not with intensity of pain in the lumbar area or perceived TF.

A retrospective case series. ⋯ This study shows that this subgroup will generally respond well to surgical correction of the pars defect and return to uninhibited competition following conservative treatment and/or surgical repair.
