Objetivo

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

Diseño

Observacional, con aplicación de las RTO y medición prospectiva del resultado. Ámbito. Urgencias hospitalarias.

Pacientes

Adultos que acudieron a urgencias por TTM desde el 1 de junio de 1999 al 31 de marzo de 2000. Fueron criterios de exclusión: edad menor de 18 años, embarazadas, graves alteraciones sensoriales y/o de la conciencia, politraumatizados y/o policontusionados, traumatismos de más de una semana de evolución, lesiones cutáneas secundarias al traumatismo, realización de radiografía en otro ámbito, gran inflamación o edema que impidiera la palpación de los relieves óseos.

Mediciones

Aplicación de las RTO y realización de radiografía a todos los pacientes, con independencia del resultado de aquéllas. Cálculo de sensibilidad, valor predictivo negativo, especificidad y valor predictivo positivo.

Resultados

Sobre una muestra de 494 pacientes, 56 presentaron fractura (11,34%), 34 de la zona maleolar (6,9%) y 22 de la zona del medio pie (4,44%). La sensibilidad de las RTO fue del 96,43% (IC del 95%, 94,8-98%). El valor predictivo negativo fue del 97,22% (IC del 95%, 95,77-98,67%). La especificidad fue del 15,98% (IC del 95%, 12,75-19,21%) y el valor predictivo positivo, del 12,8% (IC del 95%, 9,86-15,74%).

Conclusiones

Las RTO son válidas en nuestro medio como reglas de decisión a la hora de solicitar radiografías en los pacientes con TTM.

Objective

To analyse the validity of the Ottawa ankle guidelines (OAG) as clinical decision guidelines in the indications of X-rays for ankle and/or middle-foot traumas in primary care.

Design

Observational, with application of the OAG and prospective measurement of the results.

Setting

Hospital casualty.

Patients

Adults who attended casualty for ankle or middle-foot traumas between 1st June 1999 and 31th March 2000. Criteria for exclusion were: under 18, pregnancy, grave sensory and/or awareness disturbances, multi-trauma or multi-contusion patients, traumas over a week old, skin lesions as side-effects of the trauma, X-ray in other department, high inflammation or oedema hindering palpation of bone protuberances.

Measurements

Application of the OAG and X-ray on all patients, regardless of the result of the OAG. Calculation of sensitivity, negative predictive value, specificity and positive predictive value.

Results

56 of a sample of 494 patients had a fracture (11.34%), 34 in the malleolus area (6.9%) and 22 in the middle-foot area (4.44%). OAG sensitivity was 96.43% (95% CI, 94.8-98). Negative predictive value was 97.22% (95.77-98.67). Specificity was 15.98% (12.75-19.21), and positive predictive value was 12.8% (9.86-15.74).

Conclusions

The OAG are valid in primary care as guidelines to decide whether to request X-rays for patients with ankle or middle-foot traumas.
