Abstract

AIM: To investigate the feasibility of placing a screw in the C2 lamina and evaluate the reliability of the surface of the dorsal arch of C2 as a landmark for determining the optimal site of screw entry. MATERIAL and METHODS: 88 adult human C2 spines were used. Seven measurements were determined for screw entry points, trajectories, and lengths for placement of intralaminar screws. RESULTS: The average width of right C2 lamina (1/3 upper segment) was 2.6 mm (1.2 to 4.1 mm). The average width of left C2 lamina (1/3 upper segment) was 2.6 mm (1 to 4 mm). The average width of right C2 lamina (1/3 middle segment) was 4.9 mm (2.6 to 6.8 mm). The average width of left C2 lamina (1/3 middle segment) was 4.9 mm (2.3 to 7.6 mm). The average width of right C2 lamina (1/3 lower segment) was 5.7mm (3.3 to 8.2 mm). The average width of left C2 lamina (1/3 lower segment) was 5.8 mm (2.2 to 9.6 mm). CONCLUSION: The width of the upper one-third of C2 lamina is not appropriate for the placement of intralaminar screws. On the other hand, the width of the middle and lower one-third of C2 lamina is more convenient for intralaminar screw delivery.

Özet

AMAÇ: Optimal vida giriş yerini tanımlamak için bir landmark olarak C2'nin dorsal arkının yüzeyinin güvenilirliğini değerlendirmek ve C2 laminasına bir vida yerleştirmenin yapılabilirliğini incelemek. YÖNTEM ve GEREÇ: 88 adet yetişkin insan C2 vertebrası kullanıldı. 7 ölçümde intralaminar vida yerleştirmek için vida giriş noktası, seyri ve uzunluğu tanımlandı. BULGULAR: Sağ C2 laminasının ortalama eni (1/3 üst segment) 2.6 mm (1.2- 4.1 mm) idi. Sol C2 laminasının ortalama eni (1/3 üst segment) 2.6 mm (1-4 mm) idi. Sağ C2 laminasının ortalama eni (1/3 orta segment) 4.9 mm (2.6-6.8 mm) idi. Sol C2 laminasının ortalama eni (1/3 orta segment) 4.9mm (2.3-7.6 mm) idi. Sağ C2 laminasının ortalama eni (1/3 alt segment) 5.7 mm (3.3-8.2 mm) idi. Sol C2 laminasının ortalama eni (1/3 alt segment) 5.8 mm (2.2-9.6 mm) idi. SONUÇ: C2 Lamina 1/3 üst kısmının eni intralaminar vida uygulamaya uygun değildir. Diğer yandan C2 Lamina orta ve alt 1/3 kısmının eni intralaminar vida uygulamaya daha uygundur.
