Six fresh-frozen, below-knee amputation specimens were axially loaded. The results demonstrate that a properly positioned triple arthrodesis produced deltoid ligament forces that were similar to those seen with an intact tibialis posterior tendon. A triple arthrodesis in combination with a lateral displacement calcaneal osteotomy produced deltoid ligament forces that were 76% greater than those seen with the intact tibialis posterior tendon ( P &lt; .05). A triple arthrodesis in combination with a medial displacement calcaneal osteotomy produced deltoid ligament forces that were 56% less than those seen with the lateral displacement calcaneal osteotomy ( P &lt; .01).<\/jats:p>\n                  <jats:p>Patients with longstanding ruptures of the tibialis posterior tendon and associated peritalar subluxation\/dislocation may have less than optimal clinical results after triple arthrodesis, unless the hindfoot can be properly reduced, due to persistent elevated forces in the deltoid ligament and resulting ligament laxity. This study suggests that a medial displacement calcaneal osteotomy in combination with a triple arthrodesis may be a viable treatment when the hindfoot cannot be positioned properly.<\/jats:p>","DOI":"10.1177\/107110079501600104","type":"journal-article","created":{"date-parts":[[2013,3,3]],"date-time":"2013-03-03T03:31:12Z","timestamp":1362281472000},"page":"14-20","source":"Crossref","is-referenced-by-count":99,"title":["Deltoid Ligament Forces after Tibialis Posterior Tendon Rupture: Effects of Triple Arthrodesis and Calcaneal Displacement Osteotomies"],"prefix":"10.1177","volume":"16","author":[{"given":"Ronald B.","family":"Resnick","sequence":"first","affiliation":[{"name":"Former Foot Fellow, Hospital for Joint Diseases-Orthopaedic Institute, New York, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Melvin H.","family":"Jahss","sequence":"additional","affiliation":[{"name":"Chief Foot Service, Hospital for Joint Diseases-Orthopaedic Institute, and Professor, Orthopaedic Surgery, Mount Sinai School of Medicine, New York, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jack","family":"Choueka","sequence":"additional","affiliation":[{"name":"Orthopaedic Resident, Hospital for Joint Diseases-Orthopaedic Institute."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fred","family":"Kummer","sequence":"additional","affiliation":[{"name":"Associate Director, Biomechanics Department, Hospital for Joint Diseases-Orthopaedic Institute."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan C.","family":"Hersch","sequence":"additional","affiliation":[{"name":"Orthopaedic Resident, Long Island Jewish Medical Center, Long Island, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enyi","family":"Okereke","sequence":"additional","affiliation":[{"name":"Chief, Foot Service, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1995,1,1]]},"reference":[{"key":"bibr1-107110079501600104","unstructured":"1.
