Abstract

ASSUNCAO FILHO, Carlos Alberto Almeida de et al. Thoracolumbar burst fracture: radiographic evaluation on differences between Magerl's A and B. Acta ortop. bras. [online]. 2012, vol.20, n.4, pp. 235-239. ISSN 1413-7852.  http://dx.doi.org/10.1590/S1413-78522012000400010.

Objectives: Evaluate incidence of Magerl's A and B group in thoracolumbar burst fracture (Denis) according to independent examiners. Method: According to the posterior spinous process split on the anteroposterior radiography, three independent examiners have analyzed the patients admitted from 2000 to 2009 with thoracolumbar burst fractures (according to Denis) to differenciate between Magerl's type A3 and B1.2. Statistical evaluation was descriptive and by using Kappa's method. Results: From the 72 patients, 11 patients compose the Magerl's type B group according to examiner 1; 10 according to examiner 2; and 17 according to examiner 3. Posterior lesion concordance was satisfactory (good,κ=0,7) between the examiners. Conclusion: 14 to 24% patients with thoracolumbar fractures show posterior lesion (B1.2) by using radiographic criteria. Level of evidence III, Diagnostic Studies Investigating a Diagnostic Test.
