validity and reliability in qualitative research

Medial-column injuries were relatively difficult to identify (mean rate, 60.7%). Three-column injuries were most likely to be recognized (mean rate, 92.1%), followed by intermediate-lateral-column injuries (mean rate, 81.5%). ResultsĪll inter- and intra-observer reliabilities were moderate to very good (all κ coefficients > 0.4). The surgeons were then asked to suggest one of two treatment options (surgery or conservative treatment) for each case based on the radiographs and subsequently on the CT images.

A senior and junior surgeon independently completed two assessments of the same set of anonymised conventional radiographs at least 3 months apart. Diagnosis was confirmed using computed tomography. This retrospective study included 307 patients with, and 100 patients without, Lisfranc injury from January 2017 to December 2019. We aimed to determine the diagnostic validity and reliability of conventional radiography for Lisfranc injury and whether computed tomography can alter clinical decision-making. However, existing studies on conventional radiographs in Lisfranc injury lack a large population-based sample, influencing the validity of the results.

Most medical institutions prefer to use conventional radiography. Lisfranc injuries mainly involve the tarsometatarsal joint complex and are commonly misdiagnosed or missed in clinical settings.
