Digital Imaging Measurement of Hip Joint Range of Motion in Dogs

本研究探討以數位影像分析量測犬髖關節活動度之可行性，並了解影響髖關節活動度量測之可能因子。共納入41頭一至八歲齡（median，3.6歲）之健康中大型犬隻，並已排除任何臨床或放射影像下之骨骼肌肉系統異常。受測犬隻於全身麻醉後置於側臥姿，受測髖部之屈曲、伸展、外展、內展、外旋、內旋等活動範圍均由數位攝影系統加以記錄，並由同一位測試者加以分析。研究結果顯示，除外展角之外，犬隻間之年齡、性別、品種、左右側之間之各項測試角度均無統計差異，左肢之外展角平均大於右肢，而體重與外展角間成顯著負相關。數位影像分析於量測犬髖關節活動度上具有簡易且可靠之優點，但因外展角度於量測時出現較大之差異性，測試者於進行該項目之量測時應特別注意適當之出力以獲得可靠之數值。

Digital image analysis was applied to establish a simplified procedure in measuring canine hip range of motion (ROM). Factors affecting hip ROM were also investigated in healthy dogs. Forty-one healthy, 1 to 8 years old (median, 3.6 years), medium to large breed dogs without clinical or radiological orthopedic abnormalities were used in this study. Dogs were anesthetized and positioned in lateral recumbency. Ranges of hip flexion, extension, abduction, adduction, internal and external rotation were recorded with digital image and analyzed by one investigator. No significant differences were observed in age, gender, breed, and between right and left joints, except the abduction angles on the left were greater than the right. Body weight was significantly negatively correlated to abduction angles. Digital image analysis is simple and reliable in determining canine hip ROM angles. Because greater variability was noted in abduction angles, a proper manual force applied by the examiner during ROM measurement should be warranted.
