Nonunion of medial humeral condyle fractures due to functional exercise is less common.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>We report a 5-year-old patient with a nonunion HMCF due to excessive functional exercise, who bruised the elbow 1\u00a0year ago and had no positive findings on all imaging studies. On this physical examination, there was a snapping and palpable lump in the elbow joint during movement, but the patient did not feel any discomfort and the range of motion of the joint was normal. X rays and computed tomography (CT) showed that the left HMCF was discontinuous, the broken ends were dislocated, and the joint alignment was poor. Open reduction (OR) and screw fixation was used during the operation, and the patient recovered well at 3-month follow-up.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>The rarity and low radiographic appearance of displaced HMCF are easily overlooked and can eventually lead to nonunion HMCF, especially when radiographically difficult to visualize before age 5\u00a0years. Therefore, regardless of whether there are signs or imaging abnormalities in the growth process of adolescents, they should be vigilant, shorten the time interval for re-examination, and early detection and timely treatment can avoid some complications caused by this.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12891-022-05932-3","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T06:02:36Z","timestamp":1667887356000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Nonunion of humeral medial condyle fracture caused by excessive functional exercise: a case report and review of the literature"],"prefix":"10.1186","volume":"23","author":[{"given":"Liu","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Xia","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jia-chao","family":"Guo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao-lin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jin-peng","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0277-8476","authenticated-orcid":false,"given":"Jing-fan","family":"Shao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2022,11,8]]},"reference":[{"issue":"1","key":"5932_CR1","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1097\/01241398-200201000-00002","volume":"22","author":"AI Leet","year":"2002","unstructured":"Leet AI, Young C, Hoffer MM.
