In addition, we report here the clinical utility of a vascularized TM periosteal pedicled flap (VTMPF), supplied by the first dorsal metacarpal artery (FDMA), in a complex case of scaphoid nonunion.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Ten latex\u2010colored upper limbs from fresh human cadavers were used. Branches of the RA were dissected under 3x loupe magnification, noting the periosteal branches arising from the FDMA. The VTMPF was measured for both length (cm) and width (cm).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The FDMA provided a mean 12 periosteal branches (range 9 to 15), with a mean distance between branches of 0.5 cm (range 0.2\u20131.1), allowing for the design of a VTMPF which measured a mean 4 cm in length and 1.2 cm in width. We used a VTMPF to treat recalcitrant scaphoid nonunion, with a volar defect of 0.7 cm, in a 16\u2010year\u2010old boy. No bone graft was used. The patient experienced no postoperative complications. Successful consolidation was achieved three months after surgery, confirming the flap's survival. At 14\u2010months of postoperative follow\u2010up, the patient's VAS pain rating was 0 out of 100, and his DASH questionnaire score was 5. The patient had painless range that was 95% that of the contralateral limb. The patient's pinch and grip strengths were 6.5 kg and 28 kg, respectively (95% of unaffected side).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>VTMPF may be considered a valuable and reliable surgical option for scaphoid nonunion in complex clinical scenarios.<\/jats:p><\/jats:sec>","DOI":"10.1002\/micr.30233","type":"journal-article","created":{"date-parts":[[2017,9,14]],"date-time":"2017-09-14T15:23:03Z","timestamp":1505402583000},"page":"62-69","source":"Crossref","is-referenced-by-count":11,"title":["Vascularized thumb metacarpal periosteal pedicled flap for scaphoid nonunion: An anatomical study and pediatric case report"],"prefix":"10.1002","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6820-3494","authenticated-orcid":false,"given":"Sergi","family":"Barrera\u2010Ochoa","sequence":"first","affiliation":[{"name":"Pediatric Hand Surgery and Microsurgery Unit Hospital Sant Joan de Deu, Universitat de Barcelona Barcelona Spain"},{"name":"Hand and Microsurgery Unit Hospital Universitari Quiron\u2010Dexeus, ICATME Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerardo","family":"Mendez\u2010Sanchez","sequence":"additional","affiliation":[{"name":"Hand and Microsurgery Unit Hospital Universitari Quiron\u2010Dexeus, ICATME Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alfonso","family":"Rodriguez\u2010Baeza","sequence":"additional","affiliation":[{"name":"Human Anatomy and Embryology Department Faculty of Medicine, Universitat Aut\u00f2noma de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Kn\u00f6rr","sequence":"additional","affiliation":[{"name":"Pediatric Hand Surgery and Microsurgery Unit Hospital Sant Joan de Deu, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9890-5080","authenticated-orcid":false,"given":"Jayme Augusto","family":"Bertelli","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Governador Celso Ramos Hospital, Floriano\u00f3polis, Santa Catarina; Center of Biological and Health Sciences, Department of Neurosurgery, University of the South of Santa Catarina (Unisul) Tubar\u00e3o Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1759-9868","authenticated-orcid":false,"given":"Francisco","family":"Soldado","sequence":"additional","affiliation":[{"name":"Pediatric Hand Surgery and Microsurgery Unit Hospital Sant Joan de Deu, Universitat de Barcelona Barcelona Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,9,14]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/BPO.0000000000000102"},{"key":"e_1_2_7_3_1","doi-asserted-by":"crossref","first-page":"13","DOI":"10.1097\/BPO.0000000000000406","article-title":"Functional outcomes after treatment of scaphoid fractures in children and adolescents","volume":"36","author":"Bae D.
