Direct Transpedicular C2 Fixation for the Surgical Management of Hangman's Fractures: A "Second Youth" for the Judet Approach.

ABSTRACT

PURPOSE: The optimal management of hangman's fractures is controversial and the standard of care has been neither established nor supported by strong evidence. The Judet approach has been introduced in 1970 as surgical option to treat selected cases of hangman's fractures, harboring the advantage to preserve motion of the craniovertebral junction and to restore the C2 vertebra anatomy by insertion of transpedicular screws through the fracture line. This paper reviews the literature on hangman's fractures surgically managed by Judet approach, and reports two new illustrative cases. METHODS: The PubMed database was searched for the review process. After initial screening of abstracts and papers, 13 manuscripts were included in the present review.Two cases of hangman's fractures, a Levine-Edwards type I and a type IIA, respectively, treated with direct transpedicular C2 screw fixation are reported. Surgical steps of the Judet approach are also described. RESULTS: Our literature review revealed that the technique described by Judet is gaining appeal only in recent years and there is no consensus on surgical indications.No surgery-related complications were observed in the two reported cases. Patients experienced a significant reduction of neck pain postoperatively. Motion of craniovertebral junction was preserved in both patients at 3-, 6-, and 12-month follow-ups. CONCLUSIONS: Direct transpedicular osteosynthesis of C2-pars interarticularis fracture has been already demonstrated as effective in type II and IIA hangman's fractures. The application of such technique in selected patients with atypical type I fractures should also be considered in order to achieve early mobilization and avoid external fixation.
