The main objective of this work was to validate a method-Hip Congruency Index (HCI)-capable of objectively measuring the relationship between the acetabulum and the femoral head and associating it with the level of congruency proposed by the F\u00e9d\u00e9ration Cynologique Internationale (FCI), with the aim of incorporating it into a computer vision model that classifies HD autonomously. A total of 200 dogs (400 hips) were randomly selected for the study. All radiographs were scored in five categories by an experienced examiner according to FCI criteria. Two examiners performed HCI measurements on 25 hip radiographs to study intra- and inter-examiner reliability and agreement. Additionally, each examiner measured HCI on their half of the study sample (100 dogs), and the results were compared between FCI categories. The paired t-test and the intraclass correlation coefficient (ICC) showed no evidence of a systematic bias, and there was excellent reliability between the measurements of the two examiners and examiners\u2019 sessions. Hips that were assigned an FCI grade of A (n = 120), B (n = 157), C (n = 68), D (n = 38) and E (n = 17) had a mean HCI of 0.739 \u00b1 0.044, 0.666 \u00b1 0.052, 0.605 \u00b1 0.055, 0.494 \u00b1 0.070 and 0.374 \u00b1 0.122, respectively (ANOVA, p &lt; 0.01). Therefore, these results show that HCI is a parameter capable of estimating hip congruency and has the potential to enrich conventional HD scoring criteria if incorporated into an artificial intelligence algorithm competent in diagnosing HD.<\/jats:p>","DOI":"10.3390\/ani12172201","type":"journal-article","created":{"date-parts":[[2022,8,28]],"date-time":"2022-08-28T21:22:56Z","timestamp":1661721776000},"page":"2201","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Acetabular Coverage Area Occupied by the Femoral Head as an Indicator of Hip Congruency"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7925-4753","authenticated-orcid":false,"given":"Pedro","family":"Franco-Gon\u00e7alo","sequence":"first","affiliation":[{"name":"Department of Veterinary Science, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), 5000-801 Vila Real, Portugal"}]},{"given":"Diogo","family":"Moreira da Silva","sequence":"additional","affiliation":[{"name":"School of Science and Technology, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"given":"Pedro","family":"Leite","sequence":"additional","affiliation":[{"name":"Neadvance Machine Vision SA, 4705-002 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9842-1759","authenticated-orcid":false,"given":"Sofia","family":"Alves-Pimenta","sequence":"additional","affiliation":[{"name":"Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), 5000-801 Vila Real, Portugal"},{"name":"Department of Animal Science, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4879-8624","authenticated-orcid":false,"given":"Bruno","family":"Cola\u00e7o","sequence":"additional","affiliation":[{"name":"Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), 5000-801 Vila Real, Portugal"},{"name":"Department of Animal Science, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"}]},{"given":"Manuel","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Neadvance Machine Vision SA, 4705-002 Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6573-7511","authenticated-orcid":false,"given":"Lio","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"School of Science and Technology, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Department of Engineering, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Systems and Computer Engineering (INESC-TEC), Technology and Science, 4200-465 Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3747-6577","authenticated-orcid":false,"given":"V\u00edtor","family":"Filipe","sequence":"additional","affiliation":[{"name":"School of Science and Technology, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Department of Engineering, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Institute for Systems and Computer Engineering (INESC-TEC), Technology and Science, 4200-465 Porto, Portugal"}]},{"given":"Fintan","family":"McEvoy","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Sciences, Faculty of Health and Medical Sciences, University of Copenhagen, 1165 Copenhagen, Denmark"}]},{"given":"M\u00e1rio","family":"Ginja","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Veterinary and Animal Research Centre (CECAV), University of Tr\u00e1s-os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,26]]},"reference":[{"key":"ref_1","unstructured":"Congru\u00eancia (2022).
