To determine which of 3 different plate angles (20°, 25°, 30°) used in double pelvic osteotomy (DPO) would result in the most similar acetabular angle (AA) achieved with a 20° triple pelvic osteotomy (TPO) technique in dogs.
Experimental anatomic study.
Cadaveric canine pelves (n = 8).
Transverse plane computed tomographic images of cadaveric pelves with intact sacroiliac joints, mounted in a custom jig, were made (baseline) and again after DPO (20°, 25°, 30°) and TPO (20°) and pelvic angles measured in 6 transverse planes. Pelvic angles of the 3 DPO techniques were compared with TPO using concordance correlation to determine which DPO angle resulted in an acetabular ventroversion angle closest to TPO.
Mean ± SD AAs were 32.89 ± 2.23 (baseline), 47.39 ± 4.39 (20° DPO), 51.43 ± 5.06 (25° DPO), 54.75 ± 4.38 (30° DPO), and 50.20 ± 5.76 (20° TPO). Concordance correlations for the AA compared with 20° TPO were 0.027 (baseline), 0.721 (20° DPO), 0.902 (25° DPO), and 0.593 (30° DPO). A concordance correlation of ≥ 0.8 indicates good correlation.
A 25° DPO is most similar in acetabular ventroversion to 20° TPO (concordance correlation, 0.902).
确定在双骨盆截骨术（DPO）中使用的3种不同钢板角度（20°、25°、30°）中，哪一种能使犬类达到与20°三骨盆截骨术（TPO）技术最相似的髋臼角（AA）。
实验解剖学研究。
犬类尸体骨盆（n = 8）。
对安装在定制夹具中的、骶髂关节完整的犬类尸体骨盆进行横断面计算机断层扫描成像（基线），在DPO（20°、25°、30°）和TPO（20°）后再次成像，并在6个横断面上测量骨盆角度。使用一致性相关性将3种DPO技术的骨盆角度与TPO进行比较，以确定哪种DPO角度能产生最接近TPO的髋臼前倾角。
平均±标准差的髋臼角分别为32.89±2.23（基线）、47.39±4.39（20° DPO）、51.43±5.06（25° DPO）、54.75±4.38（30° DPO）和50.20±5.76（20° TPO）。与20° TPO相比，髋臼角的一致性相关性分别为0.027（基线）、0.721（20° DPO）、0.902（25° DPO）和0.593（30° DPO）。一致性相关性≥0.8表明相关性良好。
25° DPO在髋臼前倾角方面与20° TPO最相似（一致性相关性，0.902）。
