Twenty-two cases of RDA of the shoulder were retrospectively reviewed. Clinical outcomes for 15 cases who underwent shoulder arthroplasty were evaluated at an average of 41.4 months. The mean age of patients was 73.7 years (range 50\u201383 years), and there were 20 women and 2 men. The mean time from onset of symptoms to head collapse was 6.8 months (range 1\u201312 months). The mean t-score of bone mineral density was \u22123.1. Nine patients had pseudoparalysis. Based on radiographic appearance, a diversity of types of head destruction with subchondral fracture, bone marrow edema, joint effusion, and synovitis were observed in all cases. In conclusion, RDA due to SIF of the shoulder, presenting with severe short-term pain and functional disability, commonly occurred in elderly women with bone fragility. MRI revealed bone marrow edema, extensive joint effusion, and synovitis as well as a diversity of types of head destruction with subchondral fracture within several months from onset of symptoms.<\/jats:p>","DOI":"10.3390\/diagnostics10110885","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T09:29:32Z","timestamp":1604050172000},"page":"885","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Rapid Destructive Arthrosis Due to Subchondral Insufficiency Fracture of the Shoulder: Clinical Characteristics, Radiographic Appearances, and Outcomes of Treatment"],"prefix":"10.3390","volume":"10","author":[{"given":"Chul-Hyun","family":"Cho","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, Daegu 4260, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Byung-Woo","family":"Min","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, Daegu 4260, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4811-574X","authenticated-orcid":false,"given":"Kyung-Jae","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, Daegu 4260, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun-Young","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, School of Medicine, Catholic University, Daegu 42601, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Du-Han","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Keimyung University Dongsan Hospital, Keimyung University School of Medicine, Daegu 4260, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,30]]},"reference":[{"key":"ref_1","first-page":"251696","article-title":"Rapid destruction of the humeral head caused by subchondral insufficiency fracture: A report of two cases","volume":"2015","author":"Goshima","year":"2015","journal-title":"Case Rep.
