To develop a standard method of measurement for femoral angles and report values for normal Labrador Retrievers, Golden Retrievers, German Shepherds, and Rottweilers.
Retrospective evaluation of canine pelvis and femoral radiographs.
Radiographs of Labrador Retrievers, Golden Retrievers, German Shepherds, and Rottweilers (n=100 for each breed).
Anatomic lateral distal and proximal femoral angle, mechanical lateral distal and proximal femoral angle, and femoral angle of inclination were measured from radiographs.
For the 4 breeds (Labrador Retrievers, Golden Retrievers, German Shepherds, and Rottweilers, respectively) anatomic lateral distal femoral angles were 97 degrees , 97 degrees , 94 degrees , and 98 degrees ; mechanical lateral distal femoral angles were 100 degrees , 100 degrees , 97 degrees , and 100 degrees ; anatomic lateral proximal femoral angles were 103 degrees , 98 degrees , 101 degrees , and 96 degrees ; mechanical lateral proximal femoral angles were 100 degrees , 95 degrees , 97 degrees , and 93 degrees ; and inclination angles were 134 degrees , 134 degrees , 132 degrees , and 137 degrees . Labrador Retrievers, Golden Retrievers, and Rottweilers had significantly higher values for both anatomic and mechanical lateral distal femoral angle than German Shepherds. Anatomic and mechanical lateral proximal angles were greatest for Labrador Retrievers and lowest for Rottweilers.
Anatomic and mechanical femoral joint angles vary between breeds of dogs.
Values for femoral joint angles may be clinically useful for angular limb deformity diagnosis, treatment, and assessment.
制定一种测量股骨角度的标准方法，并报告正常拉布拉多寻回犬、金毛寻回犬、德国牧羊犬和罗威纳犬的测量值。
对犬骨盆和股骨X线片进行回顾性评估。
拉布拉多寻回犬、金毛寻回犬、德国牧羊犬和罗威纳犬的X线片（每个品种n = 100）。
从X线片测量解剖学外侧远端和近端股骨角、力学外侧远端和近端股骨角以及股骨倾斜角。
对于这4个品种（分别为拉布拉多寻回犬、金毛寻回犬、德国牧羊犬和罗威纳犬），解剖学外侧远端股骨角分别为97度、97度、94度和98度；力学外侧远端股骨角分别为100度、100度、97度和100度；解剖学外侧近端股骨角分别为103度、98度、101度和96度；力学外侧近端股骨角分别为100度、95度、97度和93度；倾斜角分别为134度、134度、132度和137度。拉布拉多寻回犬、金毛寻回犬和罗威纳犬的解剖学和力学外侧远端股骨角值均显著高于德国牧羊犬。解剖学和力学外侧近端角度在拉布拉多寻回犬中最大，在罗威纳犬中最小。
犬的不同品种之间，解剖学和力学股骨关节角度有所不同。
股骨关节角度值可能在临床上有助于诊断、治疗和评估肢体成角畸形。
