犬隻骨盆骨折之長期預後評估

Abstract

目的: 評估預測犬隻骨盆骨折後步態恢復與便秘發生等相關長期預後之相 關因子。 材料與方法: 回朔性調查2005~2010年之間，因骨盆骨折或其併發症而於台 大動物醫院就診的病畜。分析Messmer分級系統1對於犬隻長期步態評估之應用，同時建立新式量測方法，測量骨盆腔傾斜比例(ilium body ratio, IBR)與角度(acetabulum angle, AcA)，分析其與長期步態評估的實用性；並且追蹤在骨盆骨折時，是否有特殊危險因子造成骨盆腔的持續狹窄，以及發生便秘狀況犬隻的骨盆腔直徑比例(pelvic canal diameter ratio, PCDr)。 結果: 髀臼骨折為影響犬隻長期步態最為顯著之因子。IBR與AcA因病例數不足而不具統計上的顯著差異。在同側腸骨體與坐骨體同時發生骨折，且股骨頭仍在髀臼關節窩內時，會造成PCDr的下降。PCDr小於0.64時發生便秘的機率增加。

Purpose: Evaluate the risk factors associated with fair long-term walking gait and the potential of constipation development in canine pelvic fractures. Materials and Methods: Over a 5-year-period(2005~2010), dogs admitted to the NTUVH with pelvic fractures or associated complications were identified retrospectively. Evaluate the application of Messmer classification on evaluating long-term walking gait. Establish the new measuring methods including ilium body ratio(IBR) and acetabulum angle(AcA) to evaluate their application on evaluating long-term walking gait. Analysis the specific risk factors associated with pelvic canal stenosis and the pelvic canal diameter ratio(PCDr) associated with constipation development. Conclusions: Acetabular fracture is the most prominent risk factor influencing the canine long-term walking gait. There are no statistical difference of IBR and AcA on predicting long-term walking gait because of lack of clinical cases. When ipsilateral ilium body and ischium body fracture simultaneously with hip joint intact, the PCDr would decrease after trauma. When PCDr less than 0.64, the potential of constipation development is increased.
