This study aimed to evaluate the use of a one-stage extension shortening osteotomy of the proximal phalanx for patients with syndromic camptodactyly without tendon surgery. Forty-nine cases of syndromic camptodactyly were included. Forty fingers (81.6%) were associated with arthrogryposis multiplex congenita, and nine (18.4%) with other syndromes. Six fingers presented with a moderate form (30\u00b0 to 60\u00b0) of camptodactyly, whereas 43 fingers manifested the severe form (&gt;60\u00b0). The mean age at the time of surgery was 8.5 years, and the patients were followed for a mean of 3.9 years. The mean length of the shortening of the proximal phalanx was 4.9 mm, which averaged 17.8% of the proximal phalanx\u2019s original preoperative length. The mean operative time was 25.8 min, and the PIP joint was fixed using Kirschner wires with an average flexion position of 7.6\u00b0. The mean flexion contracture improved from 76\u00b0 preoperatively to 41\u00b0 postoperatively. The mean preoperative active arc of motion was 23\u00b0, which improved to 49\u00b0 postoperatively. A one-stage extension shortening osteotomy is a straightforward and effective technique for the improvement of finger function through the indirect lengthening of volar structures without the flexor tendon lengthening. The osteotomy could simultaneously correct bony abnormalities. This simple procedure is especially suitable for surgery on multiple fingers in patients with syndromic camptodactyly.<\/jats:p>","DOI":"10.3390\/jcm9113731","type":"journal-article","created":{"date-parts":[[2020,11,20]],"date-time":"2020-11-20T09:46:18Z","timestamp":1605865578000},"page":"3731","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["One-Stage Extension Shortening Osteotomy for Syndromic Camptodactyly"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0063-2457","authenticated-orcid":false,"given":"Byoung Kyu","family":"Park","sequence":"first","affiliation":[{"name":"Graduate School, Yonsei University College of Medicine, Seoul 03722, Korea"},{"name":"Department of Orthopaedic Surgery, Inje University Haeundae Paik Hospital, Busan 48108, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8576-1877","authenticated-orcid":false,"given":"Hyun Woo","family":"Kim","sequence":"additional","affiliation":[{"name":"Division of Pediatric Orthopaedic Surgery, Severance Children\u2019s Hospital, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8063-3742","authenticated-orcid":false,"given":"Hoon","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Gangnam Severance Hospital, Yonsei University College of Medicine, Seoul 06273, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min Jung","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, National Health Insurance Service Ilsan Hospital, Goyang 10444, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0420-8402","authenticated-orcid":false,"given":"Kee-Bum","family":"Hong","sequence":"additional","affiliation":[{"name":"Division of Pediatric Orthopaedic Surgery, Severance Children\u2019s Hospital, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8839-4870","authenticated-orcid":false,"given":"Kun Bo","family":"Park","sequence":"additional","affiliation":[{"name":"Division of Pediatric Orthopaedic Surgery, Severance Children\u2019s Hospital, Yonsei University College of Medicine, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"154","DOI":"10.1097\/00003086-197403000-00019","article-title":"An overview on new procedures in surgery of the hand","volume":"99","author":"Jones","year":"1974","journal-title":"Clin.
