Deviation of Latitude Cut: A Simple Sign to Differentiate Total Hip Arthroplasty from Hemiarthroplasty in Radiography

This study aims to propose latitude cut deviation for differentiating hip arthroplasty types and evaluate its diagnostic utility in distinguishing total (THA) from hemiarthroplasty using radiography. After assessing various cup designs top manufacturers THA hemiarthroplasty, we conducted a retrospective on 40 patients (20 20 hemiarthroplasty). Three readers independently evaluated the radiographs, acetabular sparing, cup–bone interface texture, deviation. Diagnostic performance inter-observer agreement were compared receiver operating characteristic curves Fleiss kappa coefficient. Latitude measured implant ranged 19% 42% −12% 9% THA. The sensitivity, specificity, accuracy used distinguish 60–85%, 55–95%, 62.5–77.5% sparing; 100%, 50–80%, 75–90% texture; 90–100%, 95–100% Inter-observer moderate excellent (κ = 0.499, 0.772, 0.900, respectively). exhibited inter-reader offering concise way identify type.
