Clinically, STT joint osteoarthritis is frequently observed on plain radiographs though its role in the mechanics of the wrist joint remains unclear.<\/jats:p><jats:p>\n          Questions\/Purposes\u2003Our purpose was to use a model of normal wrist types, to predict STT motion upon load.<\/jats:p><jats:p>\n          Patients and Methods\u2003Five normal computed tomography scans of a wrist type 1 and five wrist type 2 were used to model the wrist. A 200-N force was split and applied to the trapezoid and capitate to replicate forces during a knuckle pushup. The bony movement was predicted by the model as bony movement using finite element analysis.<\/jats:p><jats:p>\n          Results\u2003We found differences in force transfer through the STT joint between the two wrist types when loading the index and middle fingers. Type 1 wrists moved quantitatively more anterior-posterior, type 2 wrists moved more medially-laterally and more proximally-distally. The trapezium in type 1 wrists moved more in the coronal plane than in type 2 wrists. The trapezoid moved more from distal to proximal in a type 2 wrist, p\u2009=\u20090.03.<\/jats:p><jats:p>\n          Conclusion\/Clinical Relevance\u2003This study found differences in motion upon loading through the STT joint between type 1 and 2 wrists. Type 2 wrists moved more radially toward the proximal scaphoid and scapholunate ligament. This study may provide a mechanical basis for degenerative configurations. By linking observed patterns of degeneration to their mechanical causes we can aid in prevention of arthritis.<\/jats:p>","DOI":"10.1055\/s-0043-1761287","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T23:39:04Z","timestamp":1674689944000},"page":"413-417","source":"Crossref","is-referenced-by-count":4,"title":["Force Transfer through the Scaphotrapeziotrapezoid (STT) Joint"],"prefix":"10.1055","volume":"12","author":[{"given":"Nicholas","family":"Parody","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, School of Medicine, New York University, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shengnan","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, School of Medicine, New York University, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Catherine","family":"Petchprapa","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, School of Medicine, New York University, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9092-3930","authenticated-orcid":false,"given":"Ronit","family":"Wollstein","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, School of Medicine, New York University, New York"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2023,1,25]]},"reference":[{"issue":"04","key":"ref1","doi-asserted-by":"crossref","first-page":"539","DOI":"10.1016\/j.hcl.2005.08.001","article-title":"Scaphotrapeziotrapezoid arthrodesis for arthritis","volume":"21","author":"R Wollstein","year":"2005","journal-title":"Hand Clin"},{"issue":"01","key":"ref2","doi-asserted-by":"crossref","first-page":"227","DOI":"10.1016\/j.ocl.2015.08.002","article-title":"Scapholunate advanced collapse: motion-sparing reconstructive options","volume":"47","author":"K Kruse","year":"2016","journal-title":"Orthop Clin North Am"},{"key":"ref3","first-page":"242159","article-title":"Osteoarthritis of the wrist STT joint and radiocarpal joint","volume":"2012","author":"R Wollstein","year":"2012","journal-title":"Arthritis (Egypt)"},{"issue":"06","key":"ref4","doi-asserted-by":"crossref","first-page":"778","DOI":"10.1177\/1753193409345201","article-title":"An association between lunate morphology and scaphoid-trapezium-trapezoid arthritis","volume":"34","author":"J M McLean","year":"2009","journal-title":"J Hand Surg Eur Vol"},{"issue":"02","key":"ref5","first-page":"134","article-title":"Pyrolytic carbon arthroplasty versus suspensionplasty for trapezial-metacarpal arthritis","volume":"6","author":"M A Vitale","year":"2017","journal-title":"J Wrist Surg"},{"issue":"01","key":"ref6","doi-asserted-by":"crossref","first-page":"47","DOI":"10.1016\/j.jhsa.2006.10.021","article-title":"The clinical implications of scaphotrapezium-trapezoidal arthritis with associated carpal instability","volume":"32","author":"S C Tay","year":"2007","journal-title":"J Hand Surg Am"},{"issue":"05","key":"ref7","doi-asserted-by":"crossref","first-page":"899","DOI":"10.1053\/jhsu.2000.4582","article-title":"The scaphotrapezio-trapezoidal joint.
