目的:研究樞椎椎弓根關節突復合體的解剖結構特征,探討該解剖概念的臨床意義。方法:觀察80具樞椎干骨標本椎弓根關節突部位的解剖結構特征。并隨機抽取其中20具標本,在椎弓骨背側表面做樞椎經椎弓根螺釘固定及經關節(C1-2)螺釘固定釘道投影畫線,另2具標本按兩種螺釘內固定方式設置直徑3.5 mm釘道,并螺旋CT掃描多平面重建(MPR)釘道斷面影像,了解兩種釘道與椎弓根關節突結構的解剖關系。回顧性分析25例外傷致樞椎椎弓根關節突部位骨折的CT資料,包括其中12例樞椎螺釘內固定術后CT,研究該部位骨折特點及釘道所在的斷面解剖。結果:樞椎解剖學上,無嚴格定義下完整的椎弓根。而樞椎椎弓根關節突作為復合體,具有解剖結構上整體性特征,其周圍界線清楚。外傷致樞椎椎弓根關節突復合體骨折可分為椎弓根上關節突骨折、關節突間部骨折及單純上關節突骨折。樞椎經椎弓根螺釘固定及經關節(C1-2)螺釘內固定的釘道均通過椎弓峽部中心,但起點不同,走向不同。結論:樞椎椎弓根關節突復合體作為臨床解剖概念,具有解剖結構的完整性。明確該解剖概念及各構件對該區域骨折分類與螺釘內固定手術具有指導作用。
