Experience in the treatment, especially in the pediatric population, is scarcely reported. The duration of conservative treatment is prolonged and poses the risks of non-union and development of coxa vara deformity. The recommended treatment is closed reduction and internal fixation; however, surgery on osteopetrotic bone is challenging due to defective bone marrow function, delayed consolidation and higher risk of intraoperative fractures. Slipped capital femoral epiphysis secondary to osteopetrosis is very rarely reported. This article presents the case of a\u00a05-year-old female patient with rapidly deteriorating physical function due to bilateral proximal femoral Salter-Harris type\u00a0II fractures with associated slippage of the growth plates secondary to confirmed autosomal recessive osteopetrosis. Operative treatment was performed in a\u00a0tertiary level orthopedic center with closed reduction and internal fixation with cannulated screws. A\u00a0loss of fixation with coxa vara deformity was seen on the left side 7\u00a0months postoperatively with increasing pain. A\u00a0revision surgery with reosteosynthesis and a\u00a0valgus osteotomy was thus performed which showed good subjective and objective results 1\u00a0year postoperatively with complete bony union.<\/jats:p>","DOI":"10.1007\/s00132-022-04278-x","type":"journal-article","created":{"date-parts":[[2022,7,8]],"date-time":"2022-07-08T08:13:19Z","timestamp":1657267999000},"page":"1015-1021","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pediatric patient with a\u00a0bilateral Salter-Harris II fracture and slipped capital femoral epiphysis secondary to autosomal recessive osteopetrosis","Kind mit beidseitiger Salter-Harris-II-Fraktur und Epiphyseolysis capitis femoris bei autosomal-rezessiver Osteopetrose"],"prefix":"10.1007","volume":"51","author":[{"given":"Ayham","family":"Jaber","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Schwarze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Verena","family":"Steinle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"G\u00f6tze","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e9bastien","family":"Hagmann","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,7,8]]},"reference":[{"key":"4278_CR1","first-page":"365","volume":"51","author":"H Albers-Schonberg","year":"1904","unstructured":"Albers-Schonberg\u00a0H (1904) R\u00f6ntgenbilder einer seltenen Knochenkrankung.
