Influence of investigator experience on reliability of adult acquired flatfoot deformity measurements using weightbearing computed tomography

© 2018 European Foot and Ankle Society Background: Our purpose was to assess the reliability of measurements of adult-acquired flatfoot deformity (AAFD) taken by investigators of different levels of clinical experience using weightbearing computed tomography (WBCT). Methods: Nineteen AAFD patients underwent WBCT. Three investigators with different levels of clinical experience made AAFD measurements in axial, coronal, and sagittal planes. Intra- and interobserver reliability were assessed. Mean values for each measurement were compared between investigators. Results: After a training protocol, substantial to perfect intra- and interobserver reliability was observed for most measures, regardless of the investigator's experience level. Significant differences between investigators were observed in 2 of 21 measured parameters: medial cuneiform–first metatarsal angle (P = 0.003) and navicular–medial cuneiform angle (P = 0.001). Conclusions: AAFD radiographic measurements can be performed reliably by investigators with different levels of clinical experience using WBCT. Level of evidence: Level II, prospective comparative study.
