| 摘 要： | Objective： To compare the potential incidence of nerve root （ventral and dorsal ramus） injury caused by cervical transarticular screws and Roy-Camille lateral mass screws. Methods ： Insertion techniques with Klekamp transarticular screws and Roy-Camille lateral mass screws were respectively performed in this study. Each technique involved four specimens and 40 screws, which were inserted from C3 to C7. And 20-mm-long screws were used to overpenetrate the ventral cortex. The anterolateral aspect of the cervical spine was carefully dissected to allow observation of the screw-ramus relationship. Results ： The overall percentage of nerve invasion was significantly lower with Klekamp （45%） technique than with Roy-Camille （ 85 %） technique （ P 〈 0.05 ）. The largest percentage of nerve invasion for Klekamp transarticular screws was found at the dorsal ramus （25 % ）, followed by the ventral ramus （ 15 % ） and the bifurcation of the ventral dorsal ramus （ 5 % ）. The largest percentage of nerve invasion for Roy-Camille lateral mass screws was found at the ventral ramus （80 % ）. Conclusion ： The potential risk of nerve root invasion is lower with Klekamp transarticular screws than with Roy Camille lateral mass screws.

| Abstract: | OBJECTIVE: To compare the potential incidence of nerve root (ventral and dorsal ramus) injury caused by cervical transarticular screws and Roy-Camille lateral mass screws. METHODS: Insertion techniques with Klekamp transarticular screws and Roy-Camille lateral mass screws were respectively performed in this study. Each technique involved four specimens and 40 screws, which were inserted from C(3) to C(7). And 20-mm-long screws were used to overpenetrate the ventral cortex. The anterolateral aspect of the cervical spine was carefully dissected to allow observation of the screw-ramus relationship. RESULTS: The overall percentage of nerve invasion was significantly lower with Klekamp (45%) technique than with Roy-Camille (85%) technique (P less than 0.05). The largest percentage of nerve invasion for Klekamp transarticular screws was found at the dorsal ramus (25%), followed by the ventral ramus (15%) and the bifurcation of the ventral dorsal ramus (5%). The largest percentage of nerve invasion for Roy-Camille lateral mass screws was found at the ventral ramus (80%). CONCLUSION: The potential risk of nerve root invasion is lower with Klekamp transarticular screws than with Roy-Camille lateral mass screws. |
