Operative methods vary according to the source of donor tissue, as well as the anchor point of attachment. We present a surgical technique that diminishes tension of the repair with MCPJ flexion. Twenty-two EDC tendon stabilization procedures were performed between 2006 and 2017 using a tendon flap method. The selection criteria for this group of patients included completely dislocating extensor tendons with persistent complaints of pain and decrease in finger extension despite at least a 6-week conservative treatment attempt. All subjects underwent surgical treatment for tendon centralization using a distally based tendinous flap from the EDC sutured to the adjacent finger volar plate. A mathematical model was developed to analyze repair tension at 30, 60, and 90 degrees of MCPJ flexion calculating the flap length difference of 2 attachment points: deep transverse metacarpal ligament versus adjacent volar plate. Centralization was maintained in all digits with no evidence of subluxation at final postoperative evaluation. Clinical symptoms of pain and weakness resolved in all patients. Mathematical modeling provided evidence that translation of the anchor point of reconstructed flap to the volar plate of the adjacent finger resulted in lower tensile forces when compared with attachment at the intermetacarpal ligament. This optimized forces on reconstructed tendon flap experienced during MCPJ flexion.<\/jats:p>\n          <jats:p>\n                           <jats:bold>Level of Evidence:<\/jats:bold> Level IV\u2014therapeutic, case series.<\/jats:p>","DOI":"10.1097\/bth.0000000000000264","type":"journal-article","created":{"date-parts":[[2019,9,9]],"date-time":"2019-09-09T01:38:21Z","timestamp":1567993101000},"page":"20-25","source":"Crossref","is-referenced-by-count":4,"title":["A Reconstructive Extensor Tendon Centralization Technique for Sagittal Band Disruption"],"prefix":"10.1097","volume":"24","author":[{"given":"Oleksandra","family":"Vyrva","sequence":"first","affiliation":[{"name":"Christine M Kleinert Institute for Hand and Microsurgery, Louisville, KY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julie","family":"Kvann","sequence":"additional","affiliation":[{"name":"Christine M Kleinert Institute for Hand and Microsurgery, Louisville, KY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Karpinsky","sequence":"additional","affiliation":[{"name":"Sytenko Institute of Spine and Joint Pathology, Kharkiv, Ukraine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tuna","family":"Ozyurekoglu","sequence":"additional","affiliation":[{"name":"Christine M Kleinert Institute for Hand and Microsurgery, Louisville, KY"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2020,3]]},"reference":[{"key":"R1-20230901","doi-asserted-by":"crossref","first-page":"142","DOI":"10.1097\/00006534-196944020-00005","article-title":"Lumbrical loop operation for luxation of the extensor tendons of the hand","volume":"44","author":"McCoy","year":"1969","journal-title":"Plast Reconstr Surg"},{"key":"R2-20230901","first-page":"131","article-title":"Dislocation to extensor tendons of the hand caused by focal myoclonic epilepsy","volume":"12B","author":"Ovesen","year":"1987","journal-title":"J Hand Surg"},{"key":"R3-20230901","doi-asserted-by":"crossref","first-page":"492","DOI":"10.1016\/S0363-5023(80)80082-7","article-title":"Spontaneous recurrent ulnar dislocation of the long extensor tendons of the fingers","volume":"5","author":"Harve","year":"1980","journal-title":"J Hand Surg"},{"key":"R4-20230901","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1016\/j.jhsa.2016.10.008","article-title":"A reconstructive stabilization technique for nontraumatic or chronic traumatic extensor tendon subluxation","volume":"42","author":"Lee","year":"2017","journal-title":"J Hand Surg"},{"key":"R5-20230901","doi-asserted-by":"crossref","first-page":"79","DOI":"10.1016\/J.JHSB.2004.09.002","article-title":"Extensor mechanism laxity at the metacarpophalangeal joint as identified by a new provocative test: predisposition to dislocation","volume":"30B","author":"Shinohara","year":"2005","journal-title":"J Hand Surg (Br Eur Vol)"},{"key":"R6-20230901","doi-asserted-by":"crossref","first-page":"229","DOI":"10.2106\/00004623-197153020-00003","article-title":"Traumatic dislocation of the long finger extensor tendon","volume":"53A","author":"Kettelkamp","year":"1971","journal-title":"J Bone Joint Surg"},{"key":"R7-20230901","doi-asserted-by":"crossref","first-page":"324","DOI":"10.1302\/0301-620X.49B2.324","article-title":"Dislocation of the extensor tendons of the hand.
