Modified Halifax Interlaminar Clamp with Shaped Autograft Secured with Polydioxanone (PDS) Improves C1-C2 Fusion

Background: We describe the Halifax interlaminar clamp with shaped autograft secured technique with PDS(superscript ®) in C1-C2 fusion. Modem C1-2 fusion techniques have a potentially high risk of neurovascular injury and are highly technical. We hypothesize a Halifax interlaminar clamp with shaped autograft and PDS-secured technique for C1-2 instability is sufficient for stabilization. Methods: From May 1995 to June 2006, we conducted a retrospective review of thirty-eight consecutive patients with atlantoaxial instability who were administered a Halifax clamp with shaped bone graft, secured with PDS(superscript ®) and morselized grafts by the same neurosurgeon. Results: Over a ten-year period, thirty-eight patients received posterior stabilization of C1-2 surgery. Thirty-five patients had good results and three had complications. These cases had an average follow-up of 50 months (range 24-96 months). All patients attained solid fusion without instrument failure. Conclusions: A Halifax clamp with shaped bone graft, secured with PDS(superscript ®) and morselized grafts in C1-2 fusion, provides stability. There is no risk of neurovascular injury in sublaminar wiring, highly technical transarticular screw fixation or in lateral mass screw fixation.
