Patients and methods: This study was designed as a cross-sectional observational analysis involving 90 individuals, divided into three groups: Group A consisted of 30 individuals diagnosed with rheumatoid arthritis without clinical signs of ulnar neuropathy at the elbow; Group B\nincluded 30 individuals with rheumatoid arthritis exhibiting clinical indicators of ulnar neuropathy at\nthe elbow; and Group C comprised 30 healthy controls. Each participant underwent a thorough medical\nhistory assessment, along with both clinical and neurological evaluations. Additionally, ultrasound and\nelectrophysiological assessments of the ulnar nerve were performed. Results: There was no significant demographic difference between the groups, except for age, which was notably lower in Group A compared\nto Group B. Additionally, abnormalities in nerve conduction studies and cross-sectional area were found\nto be significantly greater in Group B (p &lt;0.0001). The cross-sectional area demonstrated diagnostic accuracy rates of 52.22%, 62.22%, and 78.89% for identifying ulnar neuropathy at Guyon\u2019s canal, the medial\nepicondyle, and based on the elbow-to-wrist ratio, respectively. Conclusion: Ultrasonography exhibits\nhigh diagnostic accuracy, especially with the cross-sectional area at the medial epicondyle and the elbowto-wrist cross-sectional area ratio serving as important indicators for ulnar nerve entrapment in patients\nwith rheumatoid arthritis.<\/jats:p>","DOI":"10.15557\/jou.2025.0013","type":"journal-article","created":{"date-parts":[[2025,4,29]],"date-time":"2025-04-29T12:20:08Z","timestamp":1745929208000},"source":"Crossref","is-referenced-by-count":0,"title":["Point-of-care ultrasound: a viable alternative for assessing ulnar neuropathy in rheumatoid arthritis?"],"prefix":"10.15557","volume":"101","author":[{"name":"Department of Rheumatology and Rehabilitation, Faculty of Medicine, Al-Azhar University, Egypt","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6619-8855","authenticated-orcid":false,"given":"Adel","family":"Azzam","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-5239-7692","authenticated-orcid":false,"given":"Mohamed","family":"Mansy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-5573-2433","authenticated-orcid":false,"given":"Abdel Hamid","family":"Ghazaly","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4730-7010","authenticated-orcid":false,"given":"Hegazy","family":"Al-Tamimy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"6250","published-online":{"date-parts":[[2025,4,18]]},"container-title":["Journal of Ultrasonography"],"original-title":[],"link":[{"URL":"https:\/\/jultrason.pl\/assets\/pdf\/artykuly\/jou-00009-2025-azzam-pdf.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,29]],"date-time":"2025-04-29T12:20:10Z","timestamp":1745929210000},"score":1,"resource":{"primary":{"URL":"https:\/\/jultrason.pl\/index.php\/issues\/volume-25-no-101-open-issue\/point-of-care-ultrasound-a-viable-alternative-for-assessing-ulnar-neuropathy-in-rheumatoid-arthritis"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,15]]},"references-count":0,"journal-issue":{"issue":"25","published-online":{"date-parts":[[2025,4,18]]},"published-print":{"date-parts":[[2025,4,15]]}},"URL":"https:\/\/doi.org\/10.15557\/jou.2025.0013","relation":{},"ISSN":["2084-8404","2451-070X"],"issn-type":[{"value":"2084-8404","type":"print"},{"value":"2451-070X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,15]]}}}
