To measure pelvic canal diameter in dogs from a ventrodorsal radiographic view of the pelvic region, to define a normal pelvic canal diameter, to evaluate risk factors associated with stenosis of the pelvic canal secondary to sacroiliac separation, and to determine clinical signs associated with pelvic canal stenosis.
Retrospective case series.
84 case-group and 46 control-group dogs.
Medical records and radiographs of dogs with conditions unrelated to pelvic fracture (control group) and dogs with sacroiliac separation (case group) in which radiographs were obtained before surgery, after surgery, or after fracture healing were reviewed. Discriminant analysis was used to determine a normal pelvic canal diameter. An ANOVA and Dunnett's two-sided test were used to determine factors associated with pelvic canal stenosis.
Pelvic canal diameter ratio determined from control-group dogs was > or = 1.1. Pelvic canal diameter ratios were significantly less for case-group dogs on radiographs obtained before surgery and after fracture healing than for control-group dogs, regardless of fracture type or treatment, except for dogs with ilial fractures treated conservatively. Pelvic canal diameter ratios did not differ for case-group dogs on radiographs obtained after surgery from those for control-group dogs, except when ilial fractures were surgically reduced. None of the dogs had clinical signs associated with pelvic canal stenosis.
Pelvic canal diameter in dogs can be determined from a ventrodorsal radiographic view of the pelvic region. Dogs with pelvic fractures that have a normal pelvic canal diameter before surgery tend to have a normal pelvic canal diameter after fracture healing.
从骨盆区域的腹背位X线片测量犬的骨盆管直径，确定正常骨盆管直径，评估与骶髂关节分离继发骨盆管狭窄相关的危险因素，并确定与骨盆管狭窄相关的临床症状。
回顾性病例系列。
84只病例组犬和46只对照组犬。
查阅与骨盆骨折无关的犬（对照组）以及骶髂关节分离犬（病例组）的病历和X线片，这些X线片是在手术前、手术后或骨折愈合后获得的。采用判别分析确定正常骨盆管直径。采用方差分析和Dunnett双侧检验确定与骨盆管狭窄相关的因素。
对照组犬的骨盆管直径比≥1.1。无论骨折类型或治疗方式如何，病例组犬在手术前和骨折愈合后的X线片上的骨盆管直径比均显著低于对照组犬，但保守治疗的髂骨骨折犬除外。病例组犬手术后X线片上的骨盆管直径比与对照组犬相比无差异，除非髂骨骨折进行了手术复位。所有犬均无与骨盆管狭窄相关的临床症状。
犬的骨盆管直径可从骨盆区域的腹背位X线片确定。术前骨盆管直径正常的骨盆骨折犬在骨折愈合后骨盆管直径往往正常。
