BackgroundTraumatic spondylolisthesis or hangman's fracture is a common cervical spine fracture. Most cases of traumatic spondylolisthesis are treated nonoperatively with external immobilization. The indications for surgery have generally included fracture instability or failed nonoperative management. Operative stabilization can be performed through either anterior or posterior approaches and has generally required instrumentation using open methods. We propose a technique for surgical repair of hangman's fracture that is minimally invasive and motion preserving using recent advances in 3-dimensional image-guidance technology. We believe this method represents another option in the treatment of hangman's fractures, because it allows for immediate stabilization, prompt recovery, and quick mobilization.Case DescriptionWe present the case of 2 patients with hangman's fractures who had undergone surgical unilateral transfixation with minimally invasive percutaneous screw placement. In both cases, we used 3-dimensional neuronavigation and bidirectional intraoperative fluoroscopy. The operative time from incision to closure was <30 minutes. Preparation and positioning after intubation varied from 40 to 150 minutes. No intraoperative complications occurred. Both patients were discharged within 48 hours postoperatively. The follow-up examinations at 3 months, 12 months, and 5 years revealed healthy bony fusion on computed tomography imaging and an excellent clinical recovery.ConclusionWe have provided 2 examples in which minimally invasive unilateral fixation of hangman's fractures proved to be safe and effective. In both cases, the patients were immediately relieved of their pain, quickly mobilized, and promptly discharged. The achievement of successful fusion confirmed at the follow-up examinations.Copyright © 2018 Elsevier Inc. All rights reserved.
