We focused on the clinical and radiographic results of SUPERhip procedures in patients with congenital femoral deficiency type 1b, according to Paley\u2019s classification, prior to femoral lengthening. Methods: We reviewed all records and radiographs of patients who underwent this procedure between 2005 and 2020. We included 26 patients, with clinical and radiographic assessments performed during pre- and post-operative evaluations. Results: There were twenty-six patients (15 right vs. 11 left), with a mean age of 7 years (1\u201318). Most of the patients were female (17 patients; 65.4%). Twenty (76.9%) patients were undergoing their first procedure and six (23.1%) had already undergone a previous surgery. There was a significant improvement in all radiographic parameters, with the mean preoperative and postoperative Neck-Shaft Angle (NSA) being 72.3 \u00b1 7.1\u00b0 vs. 133.1 \u00b1 12.7\u00b0, the Center-Edge Angle (CEA) 16.8 \u00b1 9.8\u00b0 vs. 33.5 \u00b1 14.1\u00b0, and the Acetabular Index (AI) 27.8 \u00b1 6.9\u00b0 vs. 16.4 \u00b1 6.8\u00b0, respectively. The complication rate was 15.4%, predominantly affecting patients under 5 years old. Conclusions: The SUPERhip procedure is an effective and reproducible technique for clinical and radiographic correction to a significant degree in patients with Paley\u2019s type 1b CFD, in preparation for bone lengthening surgery.<\/jats:p>","DOI":"10.3390\/children11010075","type":"journal-article","created":{"date-parts":[[2024,1,9]],"date-time":"2024-01-09T04:38:51Z","timestamp":1704775131000},"page":"75","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["SUPERhip Reconstruction Treatment in Patients with Congenital Femoral Deficiency of Paley\u2019s Classification Type 1b"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8139-1274","authenticated-orcid":false,"given":"Francisco H\u00e9lio","family":"Violante J\u00fanior","sequence":"first","affiliation":[{"name":"IAMSPE\u2013Instituto de Assist\u00eancia M\u00e9dica ao Servidor P\u00fablico Estadual, S\u00e3o Paulo 04029-000, SP, Brazil"},{"name":"Associa\u00e7\u00e3o de Assist\u00eancia \u00e0 Crian\u00e7a Deficiente\u2014AACD, S\u00e3o Paulo 04027-000, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8483-8000","authenticated-orcid":false,"given":"Fernando","family":"Farcetta J\u00fanior","sequence":"additional","affiliation":[{"name":"Associa\u00e7\u00e3o de Assist\u00eancia \u00e0 Crian\u00e7a Deficiente\u2014AACD, S\u00e3o Paulo 04027-000, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4122-9883","authenticated-orcid":false,"given":"Douglas Manuel Carrapeiro","family":"Prina","sequence":"additional","affiliation":[{"name":"IAMSPE\u2013Instituto de Assist\u00eancia M\u00e9dica ao Servidor P\u00fablico Estadual, S\u00e3o Paulo 04029-000, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5892-2532","authenticated-orcid":false,"given":"Monica Paschoal","family":"Nogueira","sequence":"additional","affiliation":[{"name":"IAMSPE\u2013Instituto de Assist\u00eancia M\u00e9dica ao Servidor P\u00fablico Estadual, S\u00e3o Paulo 04029-000, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1432","DOI":"10.2106\/00004623-200010000-00010","article-title":"Multiplier Method for Predicting Limb-Length Discrepancy","volume":"82","author":"Paley","year":"2000","journal-title":"JBJS"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2619","DOI":"10.1007\/s00264-016-3289-x","article-title":"Hip stability during lengthening in children with congenital femoral deficiency","volume":"40","author":"Eidelman","year":"2016","journal-title":"Int.
