RESUMEN

Introducción:

Se han descripto numerosas clasificaciones de rupturas del manguito rotador. Ninguna de ellas ha logrado unificar conceptos acerca del tipo de lesión, pronóstico y tratamiento. El objetivo del siguiente trabajo es validar la reproductibilidad y fiabilidad de la clasificación propuesta por Davidson y Burkhart. Materiales y

métodos:

Corte transversal retrospectivo de la fiabilidad y reproductibilidad de la clasificación geométrica de rupturas del manguito rotador. Un total de 76 pacientes fueron analizados. Se incluyeron ruptura de espesor completo con rmn realizada en hospital italiano de buenos aires. Tres observadores con diferentes niveles de experiencia (residente, fellow y medico de planta) independientemente clasificaron los estudios en dos oportunidades con un intervalo de 4 semanas.

Resultados:

El acuerdo total inter-observador para los tres observadores fue 85.1% Con un valor de kappa de 0.951 (95% Ic 0.94-0.97). El valor mas alto de fiabilidad fue alcanzado por el fellow con un valor de kappa de 0.875 (Ds ±0.047) Mientras que el score más bajo fue registrado por el residente con una puntuación de 0.815 (Sd ±0.56). De acuerdo a la guía de fleiss o de landis y koch todos los observadores alcanzaron excelente/casi perfecto acuerdo.

Conclusión:

La clasificación geométrica es comprensible y de fácil aplicación más allá del nivel de experiencia de los evaluadores. Se trata de una herramienta útil para comunicarse con excelentes resultados de fiabilidad y reproductibilidad intra e inter-observador.
ABSTRACT

Purpose:

In 2010, James Davidson and Stephen Burkhart proposed the geometric classification of rotator cuff tears a system linking tear pattern to treatment and prognosis. The objective of this study is to validate by measuring the intra-examiner and interexaminer reproducibility and reliability of the geometrical classification.

Methods:

This is a retrospective cross-sectional assessment of the reproducibility and reliability of a new rotator cuff tears classification. A total of 76 patients with full thickness rotator cuff tears on preoperative mri were analyzed. Three observers independently evaluated the mri according to the geometrical classification. The observers had different levels of experience and were represented by one resident, one medical fellow and one consultant of the arthroscopy and arthroplasty shoulder section. The mri’s were review by the observers in two occasions with 4 weeks interval to evaluate the intra-observer reliability.

Results:

The overall inter-observer agreement was 85.1% Representing a kappa value of 0.951 (95% Ci 0.94-0.97). The highest inter-observer agreement was found between the resident and the consultant with 88.2% Producing a kappa value of 0.954 (95% Ci 0.92-0.97). The highest average intra-observer reliability was achieved by the fellow with a kappa value of 0.875 (Sd ±0.047). The resident, fellow and consultant reached an excellent/almost perfect agreement.

Conclusion:

The geometrical classification is comprehensive and easy applicable despite the level of experience of the raters. It is suspect as a very useful tool to communicate among orthopedic surgeons with excellent inter and intra-observer reproducibility.
