C1–C3 Lateral Mass Screw-Rod Fixation and Fusion for C2 Pathologies and Hangman’s Fractures

다국어 초록 (Multilingual Abstract)

Study Design: Retrospective clinical study.
Purpose: We report our experience of eight patients treated with C1–C3 lateral mass rod-screw stabilization and fusion in the treatment of Hangman’s fracture and other axis pathologies.
Overview of Literature: Different surgical approaches, both anterior and posterior, have been described for treating Hangman’s fracture and other pathologies where surgery is indicated.
Methods: All patients who underwent surgical treatment for Hangman’s fracture and axial pathology where C1–C3 lateral mass screw-rod stabilization and fusion done, following reduction of the fracture or removal of the pathology were included in this series.
The recorded patient management data was retrospectively studied.
Results: There were 8 cases in total. All were male, with an average age of 40.75 years. Hangman’s fracture occurred in 6 cases (75%), one with metastatic squamous cell carcinoma and the remaining with plasmocytoma. Among the Hangman’s fractures 4 (66.66%) had no neuro-deficit. Reduction and bilateral C1–C3 lateral mass screw and rod fixation with posterior fusion by bone graft was performed in all cases. In 2 cases, a C2 body tumor was removed transorally. All patients with neuro-deficit fully recovered, except one who expired in the early post-operative period. Rest of all patients were leading a normal life till last follow up.
Conclusions: Although the number of cases was very small with a relatively short follow up period, C1 and C3 lateral mass screwrod fixation followed by fusion showed promise as an effective and biomechanically sound way for the treatment of properly selected Hangman’s fracture cases, and may also be suitable in other axial pathologies.
