Pediatric MO cases are even rarer. We report an 8-year-old girl who was diagnosed with a lateral humeral condyle fracture. She was treated surgically, and her elbow joint was fixed with plaster. Rehabilitation exercise was administered 1 month after the operation. Due to the wrong exercise method, a palpable bony mass appeared around the elbow 1 month later. The clinical radiological diagnosis showed MO, and conservative treatment was administered. After 3 years of follow-up, the affected limb functioned well, with no sign of recurrence. Here, we report this long-term follow-up case of MO resulting from excessive rehabilitation exercise.<\/jats:p>","DOI":"10.3389\/fped.2021.757147","type":"journal-article","created":{"date-parts":[[2021,11,12]],"date-time":"2021-11-12T06:43:46Z","timestamp":1636699426000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Case Report: Unusual Presentation of Myositis Ossificans of the Elbow in a Child Who Underwent Excessive Postoperative Rehabilitation Exercise"],"prefix":"10.3389","volume":"9","author":[{"given":"Jin","family":"Cao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hua Jiang","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing Hua","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huan Ye","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,11,12]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"451","DOI":"10.1007\/s002479900168","article-title":"Myositis ossificans traumatica in young children: report of three cases and review of the literature","volume":"30","author":"Gindele","year":"2000","journal-title":"Pediatr Radiol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"53","DOI":"10.1001\/archpedi.1995.02170130055012","article-title":"Radiological case of the month.
