Recent evidence has demonstrated that the dorsal ligament group is imperative for joint stability and that CMC-I joint instability may occur as a consequence of trauma and ligamentous laxity, and other conditions, with possible CMC-I subluxation and the development of osteoarthritis. Although various surgical techniques have been introduced for the treatment of ligamentous CMC-I instability, the Eaton-Littler reconstruction has been regarded as the gold standard. It is widely accepted that impaired hand function may still be present following the reconstruction of the CMC-I joint ligaments, demonstrating the existing limitations of current surgical techniques. In this paper, a novel extra-articular technique relating to CMC-I joint instability and focusing on the dorsal ligament group is described. A graft taken from the abductor pollicis longus tendon is utilized to reconstruct the dorsal radial ligament and posterior oblique ligament. This technique may provide a less invasive alternative than the gold standard procedure and the hypothesis is that it will lead to a better outcome.<\/jats:p>","DOI":"10.1097\/bth.0000000000000327","type":"journal-article","created":{"date-parts":[[2020,11,24]],"date-time":"2020-11-24T06:24:08Z","timestamp":1606199048000},"page":"169-174","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":4,"title":["First Carpometacarpal Joint Instability: Dorsal Ligament Reconstruction"],"prefix":"10.1097","volume":"25","author":[{"given":"Nenad","family":"Zeba","sequence":"first","affiliation":[{"name":"HandCenter G\u00f6teborg"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Horvath","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine and Clinical Nutrition, Institute of Medicine, Sahlgrenska Academy, Gothenburg, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anders","family":"Wallmon","sequence":"additional","affiliation":[{"name":"HandCenter G\u00f6teborg"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","published-online":{"date-parts":[[2021,9]]},"reference":[{"key":"R1-20250512","doi-asserted-by":"crossref","first-page":"1088","DOI":"10.1177\/1753193418789828","article-title":"Quantitative analysis of in-vivo thumb carpometacarpal joint kinematics using four-dimensional computed tomography","volume":"43","author":"Wang","year":"2018","journal-title":"J Hand Surg Eur Vol"},{"key":"R2-20250512","doi-asserted-by":"crossref","first-page":"66","DOI":"10.1097\/BTH.0000000000000035","article-title":"Dorsoradial ligament imbrication for thumb carpometacarpal joint instability","volume":"18","author":"Birman","year":"2014","journal-title":"Tech Hand Up Extrem Surg"},{"key":"R4-20250512","doi-asserted-by":"crossref","first-page":"238","DOI":"10.1016\/0363-5023(93)90354-6","article-title":"Contact patterns in the trapeziometacarpal joint: the role of the palmar beak ligament","volume":"18","author":"Pellegrini","year":"1993","journal-title":"J Hand Surg"},{"key":"R5-20250512","doi-asserted-by":"crossref","first-page":"182.e1","DOI":"10.1016\/j.jhsa.2017.07.028","article-title":"In vivo 3-dimensional kinematics of thumb carpometacarpal joint during thumb opposition","volume":"43","author":"Kawanishi","year":"2018","journal-title":"J Hand Surg"},{"key":"R6-20250512","doi-asserted-by":"crossref","first-page":"1468","DOI":"10.2106\/JBJS.K.00329","article-title":"Macroscopic and microscopic analysis of the thumb carpometacarpal ligaments: a cadaveric study of ligament anatomy and histology","volume":"94","author":"Ladd","year":"2012","journal-title":"J Bone Joint Surg Am Vol"},{"key":"R7-20250512","doi-asserted-by":"crossref","first-page":"310","DOI":"10.1016\/j.jhsa.2006.12.002","article-title":"Effects of the deep anterior oblique and dorsoradial ligaments on trapeziometacarpal joint stability","volume":"32","author":"Colman","year":"2007","journal-title":"J Hand Surg"},{"key":"R8-20250512","doi-asserted-by":"crossref","first-page":"386","DOI":"10.2519\/jospt.2003.33.7.386","article-title":"The carpometacarpal joint of the thumb: stability, deformity, and therapeutic intervention","volume":"33","author":"Neumann","year":"2003","journal-title":"J Orthop Sports Phys Ther"},{"key":"R9-20250512","doi-asserted-by":"crossref","first-page":"1655","DOI":"10.2106\/00004623-197355080-00010","article-title":"Ligament reconstruction for the painful thumb carpometacarpal joint","volume":"55","author":"Eaton","year":"1973","journal-title":"J Bone Joint Surg Am Vol"},{"key":"R10-20250512","doi-asserted-by":"crossref","first-page":"692","DOI":"10.1016\/S0363-5023(84)80015-5","article-title":"Ligament reconstruction for the painful thumb carpometacarpal joint: a long-term assessment","volume":"9","author":"Eaton","year":"1984","journal-title":"J Hand Surg"},{"key":"R11-20250512","doi-asserted-by":"crossref","first-page":"967","DOI":"10.1016\/S0363-5023(10)80054-1","article-title":"Osteoarthritis of the trapeziometacarpal joint: the pathophysiology of articular cartilage degeneration.
