Abstract
Purpose

To analyze the possibility of creating clinical decision- making rules to facilitate the assessment of conventional x-rays in acute wrist trauma.

Materials and methods

This is a prospective observational study. Data was collected on patients treated at the Emergency Department of our hospital further to sustaining acute wrist trauma. 179 patients were included in the study. 46 clinical interview and physical examination variables were used for each patient. Inter-examiner concordance was analyzed for the variables, as well as their statistical association with positive wrist radiology. Data was subsequently analyzed by means of multivariate analysis.

Results

All 57 patients with positive wrist x-ray images presented with at least one of these characteristics: age equal to or higher than 35, edema of the dorsum of the wrist; limited supination or active radial deviation; and pain or instability on the distal radioulnar drawer test. This clinical decision-making rule is 100% sensitive and 37.7% specific to detect patients with positive wrist x-ray images further to acute trauma. Its use in the sample under study would have reduced the number of x-ray requests by 15.6%.

Conclusions

A broader study should be undertaken in order to assess the acceptance of a series of clinical decisionmaking criteria for the carrying out of radiographs further to acute wrist trauma.

Resumen
Objetivo

Valorar la posibilidad de crear reglas de decisión clínica para el uso de la radiología convencional en los traumatismos agudos de muñeca.

Material y método

Se desarrolló un estudio observacional prospectivo. Se recogieron datos de pacientes que acudieron al Servicio de Urgencias de nuestro hospital tras sufrir un traumatismo agudo de muñeca; 179 pacientes fueron incluidos en el estudio. Se recogieron 46 variables de entrevista clínica y exploración física de cada paciente. Se analizó la concordancia inter-examinador de las variables, así como su asociación estadística con la radiología positiva de la muñeca. Los datos fueron posteriormente analizados mediante un análisis multivariante.

Resultados

Los 57 pacientes con imagen radiológica positiva de muñeca presentaron, al menos, una de las siguientes características: edad igual o superior a 35 años, edema en el dorso de la muñeca, limitación de la supinación o desviación radial activa y dolor o inestabilidad en la prueba del cajón radiocubital distal. Esta regla de decisión clínica es 100% sensible y 37,7% específica para detectar pacientes con imagen radiológica positiva de muñeca en traumatismos agudos. Su uso en la muestra estudiada hubiera ahorrado un 15,6% de peticiones radiográficas.

Conclusiones

Es necesario desarrollar un estudio más amplio para valorar la aceptación de unos criterios de decisión clínica para la realización de radiografías en los traumatismos agudos de muñeca.
