Normal values of 3 methods to determine patellar height in children from 6 to 12 years. / Valores normales de 3 métodos para determinar rótula alta en niños de 6 a 12 años.

The aim of the study was to compare three methods for high-score measurement in children, Caton-Deschamps, Blackburne-Peel and Koshino-Sugimoto, to determine the normal value of each method in a group of normal children. MATERIALS AND METHODS: A cross-sectional study on knee x-rays of normal children. Three orthopaedic surgeons measured the Caton-Deschamps, Blackburne-Peel and Koshino-Sugimoto indices. Concordance was assessed using the intraclass correlation coefficient. For interobserver variability, the measurements of each observer for each index were compared and for intraobserver variability, the coefficient between the 2 measurements was calculated by the same observer at 2 different times. RESULTS: 140 knee X-rays divided into 4 age groups were obtained. For the Blackburne-Peel index, an average median of the 3 observers was obtained of 1.07 and with P5-P95 (0.76-1.60). For the Caton-Deschamps index, an average median of the three observers of 1.22 was obtained and with P5-P95 (0.91-1.70). For the Koshino-Sugimoto index, we obtained an average median of the 3 observers of 1.16 and with P5-P95 (0.99-1.36). DISCUSSION: This study shows that the Koshino-Sugimoto index had the highest reliability, reproducibility and similarity in the population studied, both intra-observer and inter-observer. The other methods evaluated also had variability indices to be taken into account, but were inferior to the Koshino-Sugimoto index.

Uso práctico de los índices de trauma / Trauma indexes: a practical use

Presentamos una propuesta para la aplicación práctica de metodos de cuantificacion del trauma, en el Hospital San Juan de Dios de Santa Fe de Bogota. Al ingreso del paciente al servicio de Urgencias se calcula un indice fisiologico, el Revised Trauma Score (RTS). En el postoperatorio se realiza el Injury Severity Score (ISS), con base en el Abbreviated Injury Scale (AIS), que indica la severidad anatómica de la lesion. Con los anteriores datos y la edad, se calcula el Trauma Score-Injury Severity Score (TRISS), con lo que se obtiene la Probabilidad de supervivencia (Ps). Para el paciente con trauma abdominal, se calcula el Abdominal Trauma Index (ATI), como indice pronostico de complicaciones , utilizando el Organ Injury Scaling (OIS). Al paciente con trauma torácico se le cuantifica el Penetrating Thoracic Trauma Index (PTTI), con el cual se obtiene como resultado, al sumarlo con el ATI, el Penetrating Trauma Index (PTI). Con estos indices se pretende cuantificar la severidad del trauma y lograr una buena prediccion de los resultados, lo que permite evaluar la calidad de la atencion, comparar grupos e inclusive guiar politicas administrativas.
