Pediatr."],"abstract":"<jats:p>Chondroblastoma is a rare benign bone tumor that typically arises in the epiphysis. The primary treatment strategy involves complete curettage of the lesion. However, there is limited literature regarding the management of chondroblastoma specifically located in the femoral head. Following simple curettage alone, the femoral head is prone to collapse due to injury to the growth plate and the effects of weight-bearing stress. Arthrodiastasis can provide a conducive environment for healing and remodeling of the necrotic or grafted femoral head by maintaining continuous distraction of the hip joint space and reducing mechanical pressure. Analogous to the use of skeletal traction in fracture management, sustained arthrodiastasis can effectively counteract compressive forces exerted by muscular contraction on the femoral head. We present the case of a 15-year-old patient with a chondroblastoma localized in the right femoral head who demonstrated favorable clinical and radiographic outcomes following Trapdoor procedure combined with Arthrodiastasis treatment.<\/jats:p>","DOI":"10.3389\/fped.2025.1668112","type":"journal-article","created":{"date-parts":[[2025,11,6]],"date-time":"2025-11-06T12:54:43Z","timestamp":1762433683000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: Trapdoor procedure combined with arthrodiastasis treating chondroblastoma of the femoral head in adolescents"],"prefix":"10.3389","volume":"13","author":[{"given":"Yuyin","family":"Xie","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Can","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifan","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangfei","family":"Yi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhongwen","family":"Tang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Wen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sheng","family":"Xiao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,11,6]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e24.00080","DOI":"10.2106\/JBJS.RVW.24.00080","article-title":"The role of bone grafting vs. bone cement in the treatment of giant cell tumor of bone: a systematic review and meta-analysis on the risk of recurrence in 1,454 patients","volume":"12","author":"Costello","year":"2024","journal-title":"JBJS Rev"},{"key":"B2","doi-asserted-by":"publisher","first-page":"867","DOI":"10.5858\/arpa.2016-0281-RS","article-title":"Chondroblastoma: an update","volume":"141","author":"Chen","year":"2017","journal-title":"Arch Pathol Lab Med"},{"key":"B3","doi-asserted-by":"publisher","first-page":"925","DOI":"10.2106\/JBJS.N.00992","article-title":"Chondroblastoma of bone in the extremities: a multicenter retrospective study","volume":"97","author":"Xu","year":"2015","journal-title":"J Bone Joint Surg Am"},{"key":"B4","doi-asserted-by":"publisher","first-page":"944","DOI":"10.1016\/0046-8177(93)90107-r","volume":"24","author":"Turcotte","year":"1993","journal-title":"Hum Pathol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1007\/BF00361187","article-title":"Chondroblastoma: a clinical and radiological study of 104 cases","volume":"14","author":"Bloem","year":"1985","journal-title":"Skeletal Radiol"},{"key":"B6","doi-asserted-by":"publisher","first-page":"1112","DOI":"10.1016\/j.radcr.2024.10.143","article-title":"A rare case of soft tissue chondroblastoma of the quadratus femoris muscle: a case report and literature review","volume":"20","author":"Batou","year":"2025","journal-title":"Radiol Case Rep"},{"key":"B7","doi-asserted-by":"publisher","first-page":"233","DOI":"10.4103\/0970-9371.151144","article-title":"Fine needle aspiration cytology of chondroblastoma of the fibula","volume":"31","author":"Malukani","year":"2014","journal-title":"J Cytol"},{"key":"B8","doi-asserted-by":"publisher","first-page":"241","DOI":"10.4143\/crt.2009.41.4.241","article-title":"A case of spine origin chondroblastoma metastasis to lung","volume":"41","author":"Sohn","year":"2009","journal-title":"Cancer Res Treat"},{"key":"B9","doi-asserted-by":"publisher","first-page":"e28897","DOI":"10.7759\/cureus.28897","article-title":"Pulmonary metastases of chondroblastoma in a pediatric patient: a case report and review of literature","volume":"14","author":"Wing","year":"2022","journal-title":"Cureus"},{"key":"B10","doi-asserted-by":"publisher","first-page":"225","DOI":"10.5435\/JAAOS-21-04-225","article-title":"Chondroblastoma and chondromyxoid fibroma","volume":"21","author":"De Mattos","year":"2013","journal-title":"J Am Acad Orthop Surg"},{"key":"B11","doi-asserted-by":"publisher","first-page":"100691","DOI":"10.1016\/j.jbo.2025.100691","article-title":"Comparative analysis of x-ray, CT, and MRI images in patients with chondroblastoma in tubular and non-tubular bones","volume":"28","author":"Feng","year":"2025","journal-title":"J Bone Oncol"},{"key":"B12","doi-asserted-by":"publisher","first-page":"262","DOI":"10.1055\/a-1288-1209","article-title":"Chondrogenic bone tumors.
