REPRODUCIBILIDAD INTRA E INTEROBSERVADORES DE LA EVALUACIÓN RADIOGRÁFICA DE PARÁMETROS CRANEALES

ABSTRACT

Objective:

To evaluate the intra- and interobserver reproducibility of radiographic cranial parameters.

Method:

A study of the reproducibility of the radiographic cranial parameters (cranial incidence, cranial tilt, cranial slope and spinocervical angle) of 40 patients by 4 observers with different levels of experience.

Results:

Cranial incidence (CI) showed poor intraobserver concordance; for the other cranial parameters, good to excellent concordance was observed. In the assessment of interobserver concordance, all the parameters analyzed showed statistical significance, with good CI concordance.

Conclusion:

Cranial parameters are easily reproducible by orthopedists with different levels of experience. CI showed good interobserver concordance, but only reasonable intraobserver concordance among more experienced observers. Level of evidence IV; Diagnostic Study.
