Minimally invasive surgery (MIS) technique of sacroiliac luxation in toy breed dogs using cannulated screws has not been described.
The purpose of this study was to evaluate the effectiveness of pelvic canal recovery, the reproducibility of successful surgery outcomes, and the acceptable difficulty of the procedure in MIS of sacroiliac luxation in toy breed dogs.
MIS using 2.3-mm cannulated screws was demonstrated in 12 toy breed dog cadavers with sacroiliac luxation artificially induced. Pre and postoperative radiographs were used to evaluate the pelvic canal diameter ratio (PCDR), hemipelvic canal width ratio (HCWR), and reduction rate. Dorsoventral angle (DVA) and craniocaudal angle (CCA) of the inserted screw were obtained postoperative computed tomographic scan.
The statistically significant difference between the mean pre and postoperative PCDR was found (1.10 ± 0.12 and 1.26 ± 0.11, respectively; = 0.002), and the mean HCWR close to 1.0 meaning symmetric pelvis also was obtained (0.97 ± 0.07). The mean DVA and CCA were 2.26° ± 1.33° and 2.60° ± 1.86°, respectively.
MIS of sacroiliac luxation using 2.3-mm cannulated screws is applicable to toy breed dogs with acceptable difficulty.
在玩具犬种中，使用套管螺钉微创治疗骶髂关节脱位的技术尚未见报道。
本研究旨在评估骨盆管恢复的有效性、手术结果的可重复性以及在玩具犬种中微创治疗骶髂关节脱位的可接受难度。
在 12 只患有人工诱导的骶髂关节脱位的玩具犬种尸体上，采用 2.3mm 套管螺钉进行微创治疗。术前和术后的 X 射线用于评估骨盆管直径比（PCDR）、半骨盆管宽度比（HCWR）和复位率。术后计算机断层扫描获得插入螺钉的背腹角（DVA）和头尾角（CCA）。
发现平均术前和术后 PCDR 有统计学显著差异（分别为 1.10±0.12 和 1.26±0.11； = 0.002），且接近 1.0 的平均 HCWR 表示骨盆对称（0.97±0.07）。平均 DVA 和 CCA 分别为 2.26°±1.33°和 2.60°±1.86°。
使用 2.3mm 套管螺钉微创治疗骶髂关节脱位适用于玩具犬种，难度可接受。
