This study aimed to evaluate dogs with pelvic fractures and treated conservatively during locomotion on a pressure-sensing walkway. The hypothesis was that dogs may present changes in kinetic and temporospatial parameters because of the fractures, which may interfere with the symmetry index. Thirty dogs were selected and divided into two groups: Group 1-healthy group (n = 15) and Group 2-conservatively treated group (n = 15). The dogs were of similar body size. The body weight distribution percentages and symmetry indices of the peak vertical force, vertical impulse, stance time, swing time, percentage of stance time, and percentage of swing time of the hind limbs were evaluated.
In Group 2, the time interval between fracture occurrence and patient evaluation was between 4 and 87 months (mean of 20 months). Four dogs had lower percentage of body weight distribution on one of the hind limbs while three dogs had greater weight distributed toward both hind limbs. Four of these dogs had alterations in the temporospatial and/or kinetic symmetry indices.
Dogs with pelvic fractures treated conservatively may present changes in percentage of body weight distribution and symmetry indices of the kinetic and temporospatial parameters. The conservative treatment can cause persistent abnormal gait.
本研究旨在评估骨盆骨折且在压力感应步道上进行保守治疗的犬在运动时的情况。假设是骨折可能导致犬的动力学和时空参数发生变化,进而可能影响对称指数。选取30只犬并分为两组:第1组为健康组(n = 15),第2组为保守治疗组(n = 15)。这些犬的体型相似。评估了后肢垂直力峰值、垂直冲量、站立时间、摆动时间、站立时间百分比和摆动时间百分比的体重分布百分比及对称指数。
在第2组中,骨折发生至患者评估的时间间隔为4至87个月(平均20个月)。4只犬的一条后肢体重分布百分比降低,3只犬的体重向两条后肢分布更多。其中4只犬的时空和/或动力学对称指数有改变。
保守治疗的骨盆骨折犬可能出现体重分布百分比以及动力学和时空参数对称指数的变化。保守治疗可导致持续异常步态。
