This portal is ulnar to the extensor pollicis longus tendon and 1 cm distal to the V\u2010shaped cleft at the juncture of the index and thumb metacarpal bases. The entry site is marked before the tourniquet is elevated to allow palpation or Doppler ultrasound of the radial artery in the anatomic snuffbox. A 22\u2010gauge needle is inserted with proximal, radial, and palmar angulation to penetrate the joint space, which is viewed from either the 1\u2010R or 1\u2010U portal. A small skin incision is made and is followed by the insertion of a blunt trocar and cannula. An anatomic dissection of 5 cadaveric hands revealed that branches of the superficial radial nerve passed within 3.2 mm, the radial artery was 3.8 mm away, the first dorsal metacarpal artery was within 2.8 mm of this portal, and the cephalic vein was within 2.8 mm of this portal. On average, the D\u20102 portal was 17.2 mm from the 1\u2010U portal (range, 12 to 20 mm). This study provides a safe, standardized approach to the D\u20102 portal for trapeziometacarpal arthroscopy, which is useful for evaluation of the dorsal capsular ligaments, provides access to medial osteophytes during an arthroscopic partial trapeziectomy, aids in the reduction of intra\u2010articular metacarpal base fractures, and facilitates triangulation of the instruments.<\/jats:p>","DOI":"10.1016\/j.arthro.2006.12.020","type":"journal-article","created":{"date-parts":[[2007,12,1]],"date-time":"2007-12-01T01:14:04Z","timestamp":1196471644000},"source":"Crossref","is-referenced-by-count":19,"title":["The Use of a Dorsal\u2010Distal Portal in Trapeziometacarpal Arthroscopy"],"prefix":"10.1002","volume":"23","author":[{"given":"David J.","family":"Slutsky","sequence":"first","affiliation":[{"name":"Private Practice South Bay Hand Surgery Center Torrance California U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,11,1]]},"reference":[{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(96)90198-X"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(98)80067-1"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(97)80052-4"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-0712(21)00236-5"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0749-8063(03)00119-1"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2004.11.011"}],"container-title":["Arthroscopy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0749806307000229?httpAccept=text\/xml","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.elsevier.com\/content\/article\/PII:S0749806307000229?httpAccept=text\/plain","content-type":"text\/plain","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.arthro.2006.12.020","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/full-xml\/10.1016\/j.arthro.2006.12.020","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1016\/j.arthro.2006.12.020","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,3,15]],"date-time":"2026-03-15T08:40:53Z","timestamp":1773564053000},"score":1,"resource":{"primary":{"URL":"https:\/\/arthroscopyjournals.onlinelibrary.wiley.com\/doi\/10.1016\/j.arthro.2006.12.020"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,11]]},"references-count":6,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2007,11]]}},"alternative-id":["10.1016\/j.arthro.2006.12.020"],"URL":"https:\/\/doi.org\/10.1016\/j.arthro.2006.12.020","archive":["Portico"],"relation":{},"ISSN":["0749-8063","1526-3231"],"issn-type":[{"value":"0749-8063","type":"print"},{"value":"1526-3231","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007,11]]}}}
