RESUMEN
Objetivo:
Este estudio se realizó para determinar el porcentaje de cambios morfológicos,considerados fracturas vertebrales por osteoporosis en la proyección lateral de tórax, depacientes mayores de 50 anos atendidos por razones médicas distintas a problemas decolumna, en un hospital de tercer nivel.Método:
Tres investigadores evaluaron 237 radiografías digitales de tórax de pacientes conuna edad media de 66,86 anos (rango 50-90), usando de manera secuencial y estandarizadalos métodos Algorithm-Base Qualitative approach (ABQ) y de Genant. Cada evaluador contócon una pantalla de similar resolución y evaluó las radiografías de forma independiente.Resultados:
De los casos, 152 fueron del sexo femenino y 85 del masculino. La edad promedio para las fracturas grado 1 (17 casos) fue 72,17 anos con rango de 60-90(DE 8,96) y para las de grado 2 (6 casos) de 74 anos con rango de 68-87 anos (DE 6,72).Conclusiones:
El porcentaje de cambios morfológicos considerados fracturas osteoporóticasdorsales fue del 9,7% (23 fracturas), el cual resultó más bajo con respecto a lo reportado en la literatura. La distribución de las lesiones por sexo fue similar en ambos grupos yla concordancia inter e intraobservador, usando los 2 métodos de manera conjunta, fueexcelente...ABSTRACT
ObjectiveThis study was performed to determine the percentage of morphological changes considered as vertebral fractures due to osteoporosis in the lateral thorax projection of patients older than 50 years old who were attended for different medical reasons for spine problems in a third level hospital.MethodThree investigators evaluated 237 digital radiographs of the thorax of patients with a median age of 66.86 years (range 50-90) using 2 standardized methods sequentially the Algorithm-Base Qualitative approach (ABQ) method and the Genant method. Each examiner used a similar resolution screen and evaluated the radiographs independently.ResultsThe cases included 152 females and 85 males. There were 23 fractures where the distribution by Genant method was 10 (6.5%) of grade 1, and only one (0.6%) of grade 2 for a total of 11 (7.2%) in the female group. In the male group there were 7 (8.2%) of grade 1, and 5 (5.8%) of grade 2 fractures, for a total of 12 (14.1%). The total number of grade 1 fractures was 17 (7.17%) and 6 (2.53%) grade 2. The fractures identified by ABQ method were 11 (7.2%) in the female group and 12 (14.1%) in the male group.The interobserver agreement for the 3 evaluators using the Genant method had a Kappa value of 0.88 (Z of 23.59 with p > Z of 0.0) and 0.9237 (Z of 24.63 with p > Z of 0.0) by ABQ method. The agreement for each evaluator respect the consensus of them for each method had a Kappa of 0.929 for the first and second evaluators, and 0.954 for the third. Whilst using the Genant method it was 0.911, 0.886 and 0.907, respectively. Both of them with P < .005.The intraobserver agreement had a Kappa value of 0.83 and 1 for the first evaluator, 0.704 and 0.86 for the second; and, 1 and 1 for the third evaluator for ABQ and Genant methods, respectively, with P < .005.The median age for grade 1 fractures (17 cases) was 72.17 years with range 60-90 (SD of 8.96 years)...
