【摘要】：目的通过解剖膝关节来确定一个手术切口的安全区域和角度,在获取股薄肌和半腱肌肌腱时尽可能避免损伤隐神经及隐神经髌下支。方法选择膝关节新鲜标本10例,分离出隐神经及其髌下支分支。以髌韧带在胫骨结节止点的内缘处定为标志点A。经A点做一条水平线,与隐神经主干的交点定为标志点C,与隐神经髌下支的交点定为标志点B。分别测量标志点A至标志点C的距离AC和标志点A至标志点B的距离AB。通过分析和统计学计算得出手术安全区范围和切口角度。结果手术切口安全范围:A至隐神经(C点)的距离AC为(5.5±0.3)cm,A至隐神经髌下支(B点)的距离AB为(3.5±0.2)cm。手术切口的安全角度:隐神经髌下支走向为(50.7±4.8)°,隐神经胫骨结节下分支走向(43.3±5.4)°。结论手术切口的安全范围为距髌韧带在胫骨结节止点的内缘(A点)的内侧(3.5±0.2)cm以内,角度为(50.7±4.8)°。
[Abstract]:Objective to determine the safe area and angle of a surgical incision by dissecting the knee joint, and to avoid damage to the saphenous nerve and the subpatellar branch of the saphenous nerve when obtaining the tendinous and semitendinosus tendons. Methods Ten fresh specimens of knee joint were selected. The saphenous nerve and its subpatellar branch were separated. The patellar ligament was used as the mark point A at the inner edge of the tibial tubercle. A horizontal line was made through point A. The intersection with the main trunk of the saphenous nerve was taken as the marker point C, and the intersection point with the subpatellar branch of the saphenous nerve as the marker point B. the distance between marker A and marker point C was measured by measuring the distance between marker A and marker point C and the distance between marker point A and marker point B. through analysis and statistics, the distance between marker A and marker point B was measured. The range of safe area and the angle of incision were calculated. Results the distance between the safe range of surgical incision from: a to point C of saphenous nerve (AC = 5.5 卤0.3 cm) to point B of inferior patellar branch of saphenous nerve (AB) is 3.5 卤0.2 cm. The safe angle of surgical incision is: saphenous nerve. The direction of the subpatellar branch is 50.7 卤4.8 掳, and the direction of the subtubercular branch of the saphenous nerve is 43.3 卤5.4 掳. Conclusion the safe range of the surgical incision is within 3.5 卤0.2 cm of the medial side of the patellar ligament. The angle was 50.7 卤4.8 掳.
