Objetivo

Analizar la validez de las reglas del tobillo de Ottawa (RTO) como criterios de decisión clínica en nuestro medio en la solicitud de radiografías en los traumatismos de tobillo y/o medio pie.

Material y método

Estudio transversal observacional. Aplicación de las RTO a los pacientes atendidos en el servicio de Urgencias por traumatismos agudos en tobillo y/o medio pie estableciéndose si es necesario solicitar estudio radiológico para descartar fracturas. Valoración radiográfica en todos los casos de la presencia o no de fractura y correlación con el resultado clínico.

Resultados

Se incluyeron un total de 539 pacientes con traumatismo del tobillo y/o medio pie. Presentaron fractura 86 pacientes. La sensibilidad de las reglas de Ottawa fue del 96,6% (95,1-98,2%). El valor predictivo negativo fue del 98,1% (97-99,3%). La especificidad fue del 34,7% (30,6-38,7%). El valor predictivo positivo fue del 22,6% (19,1-26,2%). Con la aplicación de las reglas de Ottawa se hubiera reducido el número de radiografías realizadas en un 27,8% (156 pacientes), lo que hubiera supuesto un ahorro económico de unos 2.496 euros.

Conclusiones

Las RTO son válidas en nuestro medio como criterios de decisión clínica a la hora de solicitar radiografías en los pacientes con traumatismos de tobillo y mediopié.

Purpose

To analyze the validity of the Ottawa Ankle Rules (OARs) in our milieu as decision-making criteria for the request of x-rays in ankle or midfoot trauma.

Materials and methods

This is an observational transversal study. The OARs were applied to patients treated in the emergency department for acute trauma in the foot and/or midfoot in order to determine whether it was necessary to request a radiological study in order to rule out fractures. An x-ray assessment was made in all cases of the presence or absence of a fracture and a correlation was drawn with the patients’ clinical outcome.

Results

A total of 539 patients were included in the study that had sustained angle and/or midfoot trauma. Eighty-six patients presented with a fracture. The sensitivity of the Ottawa Rules was 96.6% (range: 95.1-98.2%). The negative predictive value was 98.1% (range: 97-99.3%). Specificity was 34.7% (range: 30.6-38.7%). The positive predictive value was 22.6% (range: 19.1-26.2%). By applying the Ottawa Rules the number of x-rays performed would have dropped by 27.8% (156 patients), which would have meant savings of around 2,496 euros.

Conclusions

OARs are valid in our milieu as clinical decision-making tools when it comes to requesting x-rays of patients with ankle and midfoot trauma.
