Reliability and agreement study, retrospective case series. ⋯ The AOSpine TL injury classification system is clinically relevant according to the consensus agreement of our international team of spine trauma experts. Final evaluation data showed reasonable reliability and accuracy, but further clinical validation of the proposed system requires prospective observational data collection documenting use of the classification system, therapeutic decision making, and clinical follow-up evaluation by a large number of surgeons from different countries.

Deep wound infections after spinal fusion in children with cerebral palsy: a prospective cohort study.
Prospective cohort. ⋯ Deep wound infection occurred in 6.4% of children with CP after spinal fusion. The presence of a gastrostomy/gastrojejunostomy tube was a significant predictor of infection. Gram-negative organisms were the most common causative agents. Surgeons should be cognizant of these factors when treating children with CP and may consider Gram-negative antibiotic prophylaxis.

Eight cases of fibrous dysplasia (FD) of the mobile spine treated surgically at the same center were retrospectively reviewed. ⋯ The radiological features of spinal FD may be atypical. The rate of correct preoperative pathological diagnosis by computed tomography-guided biopsy was low for patients with suspected spinal FD. Vertebroplasty is probably a valuable therapeutic option for spinal FD with pathological fractures. Limited decompression and stability with vertebroplasty might be recommended for patients with neurological deficits.

Cross-cultural adaptation and psychometric testing. ⋯ The reliability and construct validity of the Portuguese version of the QBPDS are acceptable to assess functional status of Portuguese-speaking patients with CLBP. .

A finite element analysis was used. ⋯ Using the Ti2448 screw system is suggested for augmenting single-level PLIF because it induces less disc intradiscal pressure at adjacent levels and the stress-shielding effect at implant-bone surface with stabilization performance compared with the Ti-6Al-4V screw system.
