This was a retrospective study. In a 12 month period we reviewed postero-anterior radiographs of 1287 patients seen at our radiology department, with complaints unrelated to the upper limb including the wrist and hand. We identified 23 cases (1.9%) of asymptomatic Lichtman stage II\u2013IV Kienb\u00f6ck\u2019s disease in our African population. The majority (63%) were male with an average age of 49 years, and 37% were female with an average age of 46.5 years. All cases were unilateral and all were in the dominant hand. Thirteen cases (57%) had an ulnar neutral wrist and the remaining ten (43%) had an ulnar negative variance. The vast majority (83%) were unemployed. Analysis of the data shed no further light on the aetiology. The relevance of ulnar variance as an aetiological factor is questioned.<\/jats:p>","DOI":"10.1177\/1753193408098481","type":"journal-article","created":{"date-parts":[[2009,5,20]],"date-time":"2009-05-20T05:55:15Z","timestamp":1242798915000},"page":"348-350","source":"Crossref","is-referenced-by-count":32,"title":["The Incidence of Asymptomatic Kienb\u00f6ck\u2019s Disease"],"prefix":"10.1177","volume":"34","author":[{"given":"U.","family":"MENNEN","sequence":"first","affiliation":[{"name":"From the Department of Hand and Microsurgery, University of Limpopo \u2013 MEDUNSA Campus and Dr George Mukhari Hospital, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"SITHEBE","sequence":"additional","affiliation":[{"name":"From the Department of Hand and Microsurgery, University of Limpopo \u2013 MEDUNSA Campus and Dr George Mukhari Hospital, South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2009,5,20]]},"reference":[{"key":"b1-0340348","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200103000-00006"},{"key":"b2-0340348","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-1383(03)00290-0"},{"key":"b3-0340348","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-197110000-00004"},{"key":"b4-0340348","doi-asserted-by":"publisher","DOI":"10.1016\/0363-5023(94)90010-8"},{"key":"b5-0340348","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(80)80013-X"},{"key":"b6-0340348","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-197557050-00017"},{"key":"b7-0340348","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-192504000-00015"},{"key":"b8-0340348","doi-asserted-by":"publisher","DOI":"10.3109\/00016922809176658"},{"key":"b9-0340348","first-page":"77","volume":"16","author":"Kienb\u00f6ck R","year":"1910","journal-title":"Fortschreiben Gebiet der R\u00f6ntgenstralen"},{"key":"b10-0340348","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681_86_90274-3"},{"key":"b11-0340348","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681_86_90275-5"},{"key":"b12-0340348","doi-asserted-by":"publisher","DOI":"10.3109\/17453676308999833"},{"key":"b13-0340348","doi-asserted-by":"publisher","DOI":"10.1007\/978-4-431-65874-0_10"},{"key":"b14-0340348","first-page":"169","volume":"18","author":"Peste JL","year":"1843","journal-title":"Bulletin of the Society of Anatomists, Paris"},{"key":"b15-0340348","unstructured":"SpeedKFractures and dislocation1916PhiladelphiaLea & Febiger826"},{"key":"b16-0340348","first-page":"962","volume":"9","author":"Taniguchi Y","year":"1993","journal-title":"Journal of the Japanese Society for Surgery of the Hand"},{"key":"b17-0340348","doi-asserted-by":"publisher","DOI":"10.1016\/0266-7681(93)90201-P"}],"container-title":["Journal of Hand Surgery (European Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1753193408098481","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/1753193408098481","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1753193408098481","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T22:43:09Z","timestamp":1777502589000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1753193408098481"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,5,20]]},"references-count":17,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2009,6]]}},"alternative-id":["10.1177\/1753193408098481"],"URL":"https:\/\/doi.org\/10.1177\/1753193408098481","relation":{},"ISSN":["1753-1934","2043-6289"],"issn-type":[{"value":"1753-1934","type":"print"},{"value":"2043-6289","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,5,20]]}}}
