Study Summary

The study is a reliability (reproducibility) study on a single measurement procedure. Reliability (reproducibility) will be assessed by repeating the whole measurement procedure twice. The measurement procedure studied is the generation of a long ankle view image based on a radiographic assessment followed by a manual assessment of the medial-distal tibial angle.

Eligibility Criteria

Inclusion

Inclusion

  • Clinical indication for a radiographic assessment of the lower half of one leg

Exclusion

Exclusion Criteria:

  • Previous bony procedures (surgery), fractures or anomalies of the lower leg, whichdoes not allow a reliable assessment of the MDTA
  • Symptomatic or clinically obvious malalignment at any level of the lower extremity

Study Description

The study is a reliability (reproducibility) study on a single measurement procedure. Reliability (reproducibility) will be assessed by repeating the whole measurement procedure twice. The measurement procedure studied is the generation of a long ankle view image based on a radiographic assessment followed by a manual assessment of the medial-distal tibial angle (MDTA).

In order to assess the value of different assessment methods of the MDTA, several variants will be considered, which are all applied to the same long ankle view image. To determine the intra- and interrater reliability of the manual assessment, this assessment will be done twice by different observers (one doctoral student, one radiologist) and repeated within each observer.
