We reviewed medical records of all our patients that underwent carpal tunnel release after scaphoid reconstruction surgery from August 2002 to December 2020. We identified a total of 7 out of 191 patients (3.7%). We investigated surgical parameters, pre- to postoperative changes, in three-dimensional measurements of the scaphoid and carpal tunnel morphometry. We found the preoperative intrascaphoid angle (ISA) and the postoperative change in ISA to correlate with an increased risk of postoperative CTS. Patients undergoing operative scaphoid reconstruction that require a high degree of geometric correction can be at risk to develop postoperative CTS, hence they should be subject to a lower threshold decision for prophylactic carpal tunnel release.<\/jats:p><jats:p>\n          Level of Evidence\u2003Level III.<\/jats:p>","DOI":"10.1055\/s-0043-1777406","type":"journal-article","created":{"date-parts":[[2023,12,22]],"date-time":"2023-12-22T23:40:28Z","timestamp":1703288428000},"page":"063-068","source":"Crossref","is-referenced-by-count":0,"title":["Carpal Tunnel Syndrome as a Complication of Surgical Scaphoid Reconstruction in Nonunion and Secondary Fracture Dislocation"],"prefix":"10.1055","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3494-0530","authenticated-orcid":false,"given":"Sophie","family":"Brackertz","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University Hospital Balgrist, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Octavian","family":"Andronic","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University Hospital Balgrist, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Reissner","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University Hospital Balgrist, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Torsten","family":"Pastor","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University Hospital Balgrist, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Schweizer","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University Hospital Balgrist, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ladislav","family":"Nagy","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, University Hospital Balgrist, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2023,12,22]]},"reference":[{"issue":"04","key":"ref1","doi-asserted-by":"crossref","first-page":"518","DOI":"10.1007\/s00776-010-1496-7","article-title":"Differential onset patterns and causes of carpal tunnel syndrome after distal radius fracture: a retrospective study of 105 wrists","volume":"15","author":"T Itsubo","year":"2010","journal-title":"J Orthop Sci"},{"issue":"01","key":"ref2","doi-asserted-by":"crossref","first-page":"76","DOI":"10.1016\/S0363-5023(98)80093-2","article-title":"Measurement of the scaphoid humpback deformity using longitudinal computed tomography: intra- and interobserver variability using various measurement techniques","volume":"23","author":"G I Bain","year":"1998","journal-title":"J Hand Surg Am"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"679","DOI":"10.1016\/0363-5023(89)90191-3","article-title":"Scaphoid malunion","volume":"14","author":"P C Amadio","year":"1989","journal-title":"J Hand Surg Am"},{"issue":"01","key":"ref4","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1016\/j.jhsa.2015.10.009","article-title":"Computer-assisted 3-dimensional reconstructions of scaphoid fractures and nonunions with and without the use of patient-specific guides: early clinical outcomes and postoperative assessments of reconstruction accuracy","volume":"41","author":"A Schweizer","year":"2016","journal-title":"J Hand Surg Am"},{"issue":"07","key":"ref5","doi-asserted-by":"crossref","first-page":"549","DOI":"10.1007\/BF00361053","article-title":"High-resolution computed tomography of the wrist in patients with carpal tunnel syndrome","volume":"15","author":"G L Merhar","year":"1986","journal-title":"Skeletal Radiol"},{"issue":"01","key":"ref6","first-page":"41","article-title":"Morphometry using computerized tomography of the wrist in idiopathic carpal tunnel syndrome.
