This was a cross-sectional study. ⋯ The modified LEFS had satisfactory psychometric properties in patients with LBP and could serve as a supplementary outcome measure to assess their activity limitations.

Comparative Study
Five-year outcomes of minimally invasive versus open transforaminal lumbar interbody fusion: a matched-pair comparison study.
Retrospective analysis of prospectively collected data. ⋯ MIS TLIF is comparable with open TLIF in terms of midterm clinical outcomes and fusion rates with the additional benefits of less initial postoperative pain, less blood loss, earlier rehabilitation, and shorter hospitalization.

Biomechanics of spinal hemiepiphysiodesis for fusionless scoliosis treatment using titanium implant.
In vitro study of the effect of hemiepiphyseal implant on biomechanical properties of porcine thoracic motion segments. ⋯ Implantation of a titanium clip-screw construct decreased range of motion by less than one-fifth, increased stiffness by one-third or less, and decreased the neutral zone by less than one-half. Range of axial translation decreased on the instrumented side and increased contralaterally. This study suggests that most of the flexibility of the spine is preserved in the immediate postoperative period after implantation of the spinal hemiepiphyseal construct.

Retrospective clinical and radiographical review. ⋯ Routine postoperative radiographical surveillance has minimal value for asymptomatic patients after anterior lumbar interbody fusion with or without posterior fusion. Obtaining a limited number of postoperative films of these patients in the absence of clinical symptoms or risk factors could significantly reduce health care costs and unnecessary radiation exposure.

Retrospective case series. ⋯ To the authors' best knowledge, this study constitutes the largest series of this sort to date, with regard to both sample size and study period. The present data indicate a decreasing proportional trend over time for SDs, MDs, and anterior TP, which can be considered a representation of an institutional learning curve during a 6-year time period of performing LLIF.
