چکیده

OBJECTIVE 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 anterior posterior radiography, three independent examiners have analyzed the patients admitted from 2000 to 2009 with thoracolumbar burst fractures (according to Denis) to differentiate 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.

Measurement of thoracolumbar kyphosis after burst fracture: evaluation of intraobserver, interobserver, and variability of 4 measurement methods.

There are various methods for measuring kyphosis after thoracolumbar burst fracture. The reliability and reproducibility of these methods are not well defined. In the study reported here, we examined 4 commonly used measurement methods in order to determine intraobserver variability, interobserver variability, and variability between measurement methods. All 4 methods were found to be accurate ...
