BACKGROUND: The target of this examine is to analyze the outcomes and security of utilizing percutaneous anterior C1/2 transarticular screw fixation as a salvage method for odontoid fracture if percutaneous odontoid screw fixation fails.
METHODS: Fifteen in 108 odontoid fracture sufferers (deliberate to be handled by percutaneous anterior odontoid screw fixation) had been didn’t introduce passable odontoid screw trajectory. To salvage this drawback, we selected the percutaneous anterior C1/2 transarticular screw fixation method in remedy of those sufferers. The visible analogue rating (VAS) of neck ache and Neck Incapacity Index (NDI) of all sufferers had been scored at pre-operation, three months after operation, and remaining follow-up. Further, technique-related problems had been recorded and picked up.
RESULTS: Percutaneous C1/2 transarticular screw fixation was carried out efficiently in all 15 sufferers whose odontoid screw fixation failed. No technique-related problems (similar to nerve damage, spinal wire damage, and esophageal damage) occurred. The VAS of neck ache and NDI rating improved considerably (P = zero.000) after operation, and no vital variations had been discovered when in comparison with 93 non-salvage sufferers who efficiently carried out the percutaneous anterior odontoid screw fixation. No screw unfastened or breakage occurred, all the odontoid fractures obtain radiographic fusion, bony fusion bridge could possibly be noticed on the C1/2 lateral articular side on 9/15 sufferers.
CONCLUSIONS: We recommend that percutaneous anterior C1/2 transarticular screw fixation is an efficient various salvage method if percutaneous odontoid screw fixation failed, and it’s a minimally invasive, possible, and protected method.
