Seventy\u2010five varus proximal osteotomies were performed on 44 children (26 females, 18 males) for hip dysplasia. Thirty\u2010nine patients had spastic CP and five had spastic diplegia; 35 patients used a wheelchair for mobility and nine could walk. Mean age at time of surgery was 8 years (SD 4 years), range 2 years 6 months to 15 years. Preoperative, immediate postoperative, and follow\u2010up (0 to 6 months, 6 months to &lt;1 year, 1 year to &lt;2 years, 2 years to &lt;4 years, 4 years to &lt;6 years, and 6 years to &lt;8 years) radiographs were reviewed. Neck\u2010shaft angles were measured. Correlations to examine the relationship between age at time of surgery and ambulatory status with postoperative changes in neck\u2010shaft angles were reviewed. Remodeling of the proximal femur does occur after varus osteotomy as long as the physes of the proximal femur show growth potential. Remodeling was quite variable between patients: children younger than 4 years old at the time of surgery remodeled more than children who were older than 4 years. Ambulatory status has little effect on the magnitude of remodeling. This study reinforces the need to follow these patients with periodic hip radiographs until completion of growth.<\/jats:p>","DOI":"10.1017\/s0012162204000660","type":"journal-article","created":{"date-parts":[[2004,5,24]],"date-time":"2004-05-24T07:38:54Z","timestamp":1085384334000},"page":"412-415","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Remodeling of the proximal femur after varus osteotomy in children with cerebral palsy"],"prefix":"10.1111","volume":"46","author":[{"suffix":"MD","given":"John M","family":"Mazur","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"MD","given":"Aileen M","family":"Danko","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"MD","given":"Shawn C","family":"Standard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"MD","given":"Eric A","family":"Loveless","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"MD","given":"R Jay","family":"Cummings","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,3,2]]},"reference":[{"key":"e_1_2_1_2_1","first-page":"337","article-title":"Femoral varus derotational osteotomy in cerebral palsy","volume":"24","author":"Atar D.","year":"1995","journal-title":"Am J Orthop"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-199301000-00007"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-199405000-00003"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-199709000-00004"},{"key":"e_1_2_1_6_1","doi-asserted-by":"crossref","first-page":"1397","DOI":"10.2106\/00004623-196345070-00006","article-title":"Varus\u2010producing and derotational subtrochanteric osteotomy in the treatment of congenital dislocation of the hip","volume":"45","author":"Chuinard EG.","year":"1963","journal-title":"J Bone Joint Surg Am"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/01241398-198705000-00005"},{"key":"e_1_2_1_8_1","first-page":"168","article-title":"Varus derotational osteotomy of the femur in cerebral palsy","volume":"125","author":"Eilert RE.","year":"1977","journal-title":"Clin Orthop"},{"key":"e_1_2_1_9_1","first-page":"1","article-title":"Some aspects of congenital dysplasiaofthe hip","volume":"43","author":"Eyre\u2010Brook AL.","year":"1968","journal-title":"Ann R Coll Surg Engl"},{"key":"e_1_2_1_10_1","doi-asserted-by":"crossref","first-page":"152","DOI":"10.1302\/0301-620X.59B2.873975","article-title":"Sub\u2010capital coxa valga after varus osteotomy for congenital dislocation of the hip","volume":"59","author":"Jones DA.","year":"1977","journal-title":"J Bone Joint Surg Br"},{"key":"e_1_2_1_11_1","doi-asserted-by":"crossref","first-page":"666","DOI":"10.1302\/0301-620X.48B4.666","article-title":"Pitfalls in the management of congenital dislocation of the hip","volume":"48","author":"Lloyd\u2010Roberts GC.","year":"1966","journal-title":"J Bone Joint Surg Br"},{"key":"e_1_2_1_12_1","first-page":"285","article-title":"Spontaneous straightening of the femoral neck following adduction osteotomy in congenital dysplasia of the hip","volume":"43","author":"Mau H.","year":"1961","journal-title":"J Bone Joint Surg Am"},{"key":"e_1_2_1_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469-8749.1979.tb01696.x"},{"key":"e_1_2_1_14_1","doi-asserted-by":"crossref","first-page":"169","DOI":"10.1097\/00003086-198303000-00022","article-title":"The untreated unstable hip in severe cerebral palsy","volume":"173","author":"Pritchett JW.","year":"1983","journal-title":"Clin Orthop Rel Res"},{"key":"e_1_2_1_15_1","first-page":"237","article-title":"Treatment of hip problems in cerebral palsy","volume":"36","author":"Root L.","year":"1987","journal-title":"Instr Course Lect"}],"container-title":["Developmental Medicine &amp;
