Limb length discrepancy is a common problem in patients with Ollier\u2019s and Maffucci\u2019s enchondromatosis. There are multiple reports about lengthening bones in patients with enchondromatosis using external fixators. However, there are no case series regarding the use of implantable lengthening technology. The purpose of this paper is to describe our experience with implantable nail lengthening in patients with enchondromatosis. A retrospective chart and radiographic review of patients with enchondromatosis who underwent implantable nail limb lengthening was performed. Seven patients with 14 bony segments were reviewed. A total of 11\/14 lengthenings were completed without difficulty. There were no issues in terms of fixation location in patients with Ollier\u2019s disease. One patient with Maffucci\u2019s syndrome experienced migration of the nail during two lengthenings due to a combination of intralesional fixation and preconsolidation. One patient with Ollier\u2019s disease developed a knee extension contracture requiring manipulation under anesthesia. No other complications were recorded. The use of implantable nail lengthening to resolve limb length discrepancies in patients with Ollier\u2019s disease appears to be safe and effective.<\/jats:p>","DOI":"10.3390\/children8060502","type":"journal-article","created":{"date-parts":[[2021,6,14]],"date-time":"2021-06-14T10:30:25Z","timestamp":1623666625000},"page":"502","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Lengthening the Lower Extremities of Children with Ollier\u2019s and Maffucci\u2019s Enchondromatosis Using Implantable Lengthening Nails"],"prefix":"10.3390","volume":"8","author":[{"given":"Aaron J.","family":"Huser","sequence":"first","affiliation":[{"name":"Paley Institute, West Palm Beach, FL 33407, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7065-0656","authenticated-orcid":false,"given":"Jason Shih","family":"Hoellwarth","sequence":"additional","affiliation":[{"name":"Paley Institute, West Palm Beach, FL 33407, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1849-2862","authenticated-orcid":false,"given":"Valentino","family":"Coppa","sequence":"additional","affiliation":[{"name":"Paley Institute, West Palm Beach, FL 33407, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David S.","family":"Feldman","sequence":"additional","affiliation":[{"name":"Paley Institute, West Palm Beach, FL 33407, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8249-3459","authenticated-orcid":false,"given":"Dror","family":"Paley","sequence":"additional","affiliation":[{"name":"Paley Institute, West Palm Beach, FL 33407, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1007\/s11914-020-00639-7","article-title":"Enchondromatosis and growth plate development","volume":"19","author":"Zhang","year":"2021","journal-title":"Curr.
