The influence of fracture mechanism and morphology on the reliability and validity of two novel thoracolumbar injury classification systems.

摘要: STUDY DESIGN The Thoracolumbar Injury Severity Score (TLISS) and the Classification (TLICS) were prospectively evaluated. OBJECTIVES To compare reliability validity of TLISS TLICS schemes to determine importance injury mechanism morphology identification treatment thoracolumbar fractures. SUMMARY OF BACKGROUND DATA Two novel algorithms have been developed for categorization management injuries: system emphasizing scheme involving morphology. METHODS clinical radiographic findings 25 patients with fractures presented 5 groups surgeons disparate levels training experience spinal trauma. These injuries consecutively scored, first using then 3 months later TLICS. recommended treatments proposed by 2 compared actual each patient. RESULTS For both algorithms, interrater kappa statistics all subgroups (mechanism/morphology, status posterior ligaments, total score, predicted management) within range moderate substantial reproducibility (0.45-0.74), there no statistically significant differences noted between respective values. Interrater correlation was higher paradigm on mechanism/morphology, integrity (P < or = 0.01). exhibited excellent overall validity. CONCLUSIONS Although validity, our results indicate is more reliable than TLICS, suggesting that trauma may be a valuable parameter fracture classification injuries. Since these characteristics are interrelated critical maintenance stability, we think concepts should considered during assessment patients.
