韓国人集団におけるトランストランスミナースクリュー配置の実現可能性：頸椎の形態計測分析

目的：コーラン集団における一方的および両側性的翻訳スクリューの配置の実現可能性を分析し、アメリカ人口で以前に報告されたデータを使用して受け入れ率を比較します。 材料と方法：回訳の長さ、厚さ、高さ、および矢状角角測定が行われました。実現可能性分析は、安全マージンから0.5 mm以内のCTスキャンの片側および両側3.5 mmの頸部ねじ配置を使用して実行されました。また、C3-C7での一方的および両側性翻訳のねじの配置の形態計測寸法と実現可能性のX線撮影分析を実行しました。 RESULTS: Korean population had similar or significantly shorter translaminar lengths and thickness (lengths and thickness in C7 among males; lengths in C6-C7 and thickness in C4 among females) than American population, but had similar or significantly longer translaminar heights and sagittal-diagonal measurements (heights in C3-C7 and sagittal-diagonal measurements in C3-C6 among males; heights in C7 and女性のC3-C7の矢状角測定）。一方的には、C3-C7のトランスラミナースクリューの受け入れ率は韓国人とアメリカの男性人口の間で類似していたが、C4-C6の率は韓国人とアメリカの女性人口の間で著しく小さかった。二国間では、C3およびC5-C6のトランスラミナースクリューの受け入れ率は韓国人とアメリカの男性人口の間で有意に大きかったが、C3-C7の率は韓国人とアメリカの女性人口の間で類似していた。 結論：一方的および両側性的翻訳のネジの配置の実現可能性は、民族によって異なります。韓国の男性人口の間の軸頸部片側翻訳のねじの配置と韓国の女性集団におけるC4-C7での両側の配置は、アメリカ人口よりも受け入れられています。

PURPOSE: To analyze the feasibility of unilateral and bilateral translaminar screw placement in Koran population, and compare the acceptance rate using previously reported data in American population. MATERIALS AND METHODS: The translaminar lengths, thickness, heights, and sagittal-diagonal measurements were performed. The feasibility analysis was performed using unilateral and bilateral 3.5 mm cervical screw placement on the CT scans within 0.5 mm of safety margin. We also performed radiographic analysis of the morphometric dimensions and the feasibility of unilateral and bilateral translaminar screw placement at C3-C7. RESULTS: Korean population had similar or significantly shorter translaminar lengths and thickness (lengths and thickness in C7 among males; lengths in C6-C7 and thickness in C4 among females) than American population, but had similar or significantly longer translaminar heights and sagittal-diagonal measurements (heights in C3-C7 and sagittal-diagonal measurements in C3-C6 among males; heights in C7 and sagittal-diagonal measurements in C3-C7 among females). Unilaterally, translaminar screw acceptance rates in C3-C7 were similar between Korean and American male population, but the rates in C4-C6 were significantly smaller between Korean and American female population. Bilaterally, translaminar screw acceptance rates in C3 and C5-C6 were significantly larger between Korean and American male population, but the rates in C3-C7 were similar between Korean and American female population. CONCLUSION: The feasibility of unilateral and bilateral translaminar screw placement is different depending on different ethnics. Subaxial cervical unilateral translaminar screw placement among Korean male population and bilateral placement at C4-C7 among Korean female population are more acceptable than American population.
