“…Direct pars fixation with bilateral C2 screws conducted from a posterior approach has been discussed as a motion-preserving alternative surgical method for hangman's fractures that have limited disk and ligament injury. 7,47 , 48 , 49 , 50 In the systematic review, the fusion rate of type 3 fractures was similar for those treated posteriorly (39%) and anteriorly (43%). 35…”

“… 34 If surgery is deemed necessary, the posterior approach allows direct access to the C2–C3 facet joints for reduction (necessary in type 3 fractures) and correction of local kyphosis, but requires considerable muscle dissection followed by C1–C3 or C2–C3 instrumented fusion. 7 35 44 The anterolateral approach with autologous bone graft allows for a C2–C3 diskectomy and fusion if traumatic disk herniation compromises the spinal cord. Plate and screws may be used.…”

Study Design Retrospective study of a prospectively maintained database. Objective Our aim was to retrospectively review management and outcomes of patients with low-grade hangman's fractures, specifically looking at differences in outcomes between collars and halo immobilization. We also studied fracture patterns and their treatment outcomes. Methods Forty-one patients with hangman's fractures were identified from 105 patients with axis fractures between 2007 and 2013. Typical hangman's fractures were defined as traumatic spondylolisthesis of the axis causing a bilateral pars interarticularis fracture. Fractures involving the posterior cortex of C2 on one or both sides or an asymmetrical pattern were defined as atypical. Results There were 41 patients with a mean age of 59 years, with 13 (31.7%) typical and 28 (68.2%) atypical fractures. There were 22 (53.6%) type 1 fractures, 7 (41.4%) type 2 fractures, and 2 (4.9%) type 2a fractures in this series. Cervical collars were used to manage 11 patients (27% of all patients with hangman's fractures) and halo orthosis was used in 27 (65.8%). Three (7.3%) patients underwent surgical fixation of the fracture. Bony union was achieved in all patients on radiologic follow-up. Permanent neurologic deficit occurred in one patient due to associated injuries. Neck pain and stiffness were reported more commonly in the atypical group, but this finding was not statistically significant. Conclusions The majority of hangman type fractures can be treated nonoperatively. We found no difference in outcomes between a rigid collar or halo immobilization for treatment of low-grade fractures. Radiologic follow-up is essential to identify cases of nonunion.

“…[4–7] Hangman fractures have been explored and understood for several decades but treatment strategies still remain controversial. [8] Treatment methods included nonoperative treatments such as traction and various types of external immobilization, anterior cervical discectomy and fusion (ACDF) with or without anterior plating at C2--3, posterior fixation and fusion of C2-3, posterior fixation and fusion of C1--3, posterior percutaneous transpedicular screw fixation, and an anterior-posterior union approach. [9–13] Different studies have presented different concepts for the treatment of Hangman fractures with approximately 40 concepts in total according to previous reviews.…”

This research aims to explore the accurate incidence, severity and outcomes of dysphagia and dysphonia after Hangman fractures.A total of 93 patients were included in this study and clinical data were reviewed. The Bazaz grading system (0-None; 1-Mild; 2-Moderate; 3-Severe) was used for dysphagia evaluation and the Voice Handicap Index-10 used to evaluate dysphonia. In all of the patients, evaluation of dysphagia and dysphonia was performed preoperatively and at 1 week, 1 month, 3, 6, and 12 months after surgery. SPSS 22.0 software (SPSS Inc, Chicago, IL) was used for all statistical analyses.Posttraumatic immediate dysphagia was found in 8 patients and posttraumatic immediate dysphonia was observed in 3 patients. The incidence of dysphagia was 22.6% at the 1st week, 16.1% at the 1st month, and 9.7% at the 3rd month of follow-up. The incidence of dysphonia was 24.5% at the 1st week, 11.3% at the 1st month, and 3.8% at the 3rd month of follow-up.Posttraumatic immediate dysphagia and dysphonia occurred and the anterior surgical approach was associated with a higher incidence of dysphagia compared to posterior surgery and nonoperative patients. Most dysphagia and dysphonia were mild and gradually decreased during the subsequent 3 months after surgery. Future prospective, randomized studies with larger sample sizes are required to validate these data.
