Spine

Experimental study. ⋯ In this quadruped straight spine model, in comparison with IF applications, FI is closer to normal physiology even after several lengthening procedures regarding the adjacent segment discs, facet joints, and motion, when interpreting the radiological, biomechanical, and histological results altogether.

Multicenter Study
No relationship between body mass index and changes in pain and disability after exercise rehabilitation for patients with mild to moderate chronic low back pain.
A retrospective multicenter study. ⋯ There was no significant relationship between BMI and self-reported pain and disability in cLBP participants. BMI was not a predictor of exercise-induced changes in pain and disability. The reliance on BMI as a sole measurement of obesity in cLBP research may be unwarranted.

Multicenter Study
Complications in pediatric spine surgery using the vertical expandable prosthetic titanium rib: the French experience.
Multicenter retrospective study of 54 children. ⋯ The complication rate is consistent with that reported in the literature. Correct determination of the levels to be instrumented, preoperative improvement of nutritional status, and better evaluation of the preoperative and postoperative respiratory function are important factors in minimizing the potential complications of a technique that is used in weak patients with complex deformities.

Case report. ⋯ The authors think that this is an effective method for reduction of these severe fractures.
