To radiographically define the anatomic origin and insertion of the cranial cruciate ligament translated to the lateral radiographic projection of the stifle (CrCL-Lo and CrCL-Li, respectively), to correlate these landmarks for identification of the CrCL-Lo intraoperatively, and to compare the isometry of the CrCL-Lo to the lateral fabella.
Experimental study.
Pelvic limbs (n = 12) from dogs weighing 13-26 kg.
A radiographic quadrant method was used to localize the CrCL-Lo. Mediolateral radiographic projections of each stifle were taken through a range of motion. Maximum percent change in length between each tibial marker and femoral marker during range of motion determined isometry.
The CrCL-Lo is located at the caudal 33% and distal 50% of the lateral femoral condyle using Blumensaat's line or a line from the origin of the long digital extensor (LDE) to the lateral fabella, with no significant difference (P = .766) between the 2 reference lines. The CrCL-Li is located at the proximal 20% of the tibial plateau. No significant difference (P < .05) in isometry was found between the CrCL-Lo and lateral fabella.
The CrCL-Lo is located at the caudal 1/3 and distal ½ of the lateral femoral condyle. The CrCL-Lo and lateral fabella are not significantly different in isometry when used as a proximal anchor point in extracapsular stifle stabilization.
通过X线片确定颅交叉韧带在膝关节外侧X线投影上的解剖起点和止点（分别为CrCL-Lo和CrCL-Li），关联这些标志以便术中识别CrCL-Lo，并比较CrCL-Lo与外侧腓肠豆的等长性。
实验研究。
体重13 - 26千克犬的骨盆肢（n = 12）。
采用X线象限法定位CrCL-Lo。在一系列运动过程中拍摄每个膝关节的内外侧X线投影。通过运动范围内每个胫骨标记和股骨标记之间长度的最大百分比变化来确定等长性。
使用布卢门萨特线或从长指伸肌（LDE）起点到外侧腓肠豆的线时，CrCL-Lo位于股骨外侧髁的尾侧33%和远侧50%处，两条参考线之间无显著差异（P = 0.766）。CrCL-Li位于胫骨平台的近侧20%处。CrCL-Lo与外侧腓肠豆之间在等长性方面未发现显著差异（P < 0.05）。
CrCL-Lo位于股骨外侧髁的尾侧1/3和远侧1/2处。当用作关节外膝关节稳定术的近端锚点时，CrCL-Lo与外侧腓肠豆在等长性方面无显著差异。
