Multicenter Study
Challenges of local recurrence and cure in low grade malignant tumors of the spine.
Systematic review and ambispective multicenter cohort study. ⋯ When wide or marginal margins (en bloc) are achieved in surgical resection of chordomas and chondrosarcomas of the spine there is a decrease in local recurrence and mortality. Therefore, en bloc resection should be undertaken for the treatment of chordomas and chondrosarcomas of the spine. Strong Recommendation, Moderate Quality Evidence.Radiation therapy of at least 60 to 65 Gy equivalents is indicated as an adjuvant treatment for chordoma and chondrosarcoma of the spine when there has been incomplete resection or an intralesional margin. Weak Recommendation, Low Quality Evidence.

Prospective cohort study. ⋯ MDR-TB of the spine is a different disease and is here to stay. There is an urgent need to include culture and drug susceptibility testing in the protocol for the treatment of tuberculosis of the spine.

Prospective cross-sectional measurement study. ⋯ Pain, self-image, and satisfaction scores could discriminate among management subgroups, but function, mental health and total scores could not. The total score and all domain scores except satisfaction discriminated among curve-severity subgroups. Using discriminant analysis, self-image was the only domain retained in a model predicting curve-severity categories.

In vitro laboratory study. ⋯ High injection speed, high viscosity, small diameter, and a long needle increase the dynamic pressure. To minimize the differences among examiners, we recommend standardization of injection speed, the viscosity of the injected material, and the diameter and length of the needle.

Comparative Study
A criterion measure of walking capacity in lumbar spinal stenosis and its comparison with a treadmill protocol.
Measurement (validity) study. ⋯ The SPWT is presented as a feasible and reproducible criterion measure of walking capacity for use with LSS patients. Although a strong relationship was demonstrated between the treadmill protocol and the SPWT, a systematic bias was observed with patients walking significantly further in the SPWT (36% in mean).
