A retrospective study was undertaken to assess the safety and efficacy of nonrigid immobilization in the treatment of these fractures.<\/jats:p><jats:p content-type=\"fine-print\">Records of 64 patients with hangman's fracture treated over a 19-year period (1975\u20131994) at one institution were reviewed. Thirty-nine of these patients presented with a displacement of C-2 onto C-3 measuring less than 6 mm and no contiguous cervical fractures. All these patients were treated with nonrigid immobilization, consisting primarily of a Philadelphia hard collar worn for 10 to 14 weeks; all showed stable fracture healing on follow-up flexion\u2014extension radiographs. None of the patients experienced neurological sequelae or significant disability at follow-up review.<\/jats:p><jats:p content-type=\"fine-print\">The results of this series indicate that the majority of patients with hangman's fractures, including all patients with displacement measuring less than 6 mm and no contiguous fractures, may be treated successfully with nonrigid immobilization. This management regimen avoids the increased morbidity and cost associated with rigid immobilization using a halo orthosis.<\/jats:p>","DOI":"10.3171\/jns.1996.85.4.0550","type":"journal-article","created":{"date-parts":[[2009,6,8]],"date-time":"2009-06-08T21:57:42Z","timestamp":1244498262000},"page":"550-554","source":"Crossref","is-referenced-by-count":75,"title":["Treatment of traumatic spondylolisthesis of the axis with nonrigid immobilization: a review of 64 cases"],"prefix":"10.3171","volume":"85","author":[{"given":"Domagoj","family":"Coric","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John A.","family":"Wilson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David L.","family":"Kelly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","unstructured":"Benzel EC:Biomechanics of Spine Stabilization.
