To characterize the computed tomographic (CT) and cross-sectional anatomic features of myofascial compartments and soft tissue spaces in the manus of cadavers of dogs without forelimb disease.
33 cadavers of adult medium- to large-breed dogs without forelimb disease.
Forelimbs were removed from the cadavers within 4 hours after euthanasia or within 6 hours after thawing from initial freezing. Specimens were then frozen for variable periods and thawed for approximately 16 hours before use. Each manus of 60 forelimbs underwent CT before and after injection of a radiopaque, blue-staining contrast medium into locations where soft tissue spaces and myofascial compartments were predicted (on the basis of pilot study data [6 forelimbs]). Two veterinary radiologists reviewed CT images and recorded the presence or absence of a discrete space or compartment at each injection site. Each manus was subsequently dissected or sectioned transversely. Locations of blue-staining contrast medium accumulation were compared with locations of contrast enhancement in CT images. Anatomic structures within each soft tissue space or myofascial compartment were described.
13 soft tissue spaces and 5 myofascial compartments were identified in the manus. Three myofascial structures that were examined were determined not to be compartments.
Knowledge of soft tissue spaces and myofascial compartments are used to map the likely spread of disease in the hands and feet of humans. Thus, understanding the locations and extent of similar structures in the canine manus may improve the effectiveness of surgical interventions in dogs with injury or inflammation of this region of the forelimb.
描述无前肢疾病犬尸体手部肌筋膜间隙和软组织间隙的计算机断层扫描（CT）及横断面解剖特征。
33具无前肢疾病的成年中大型犬尸体。
在安乐死后4小时内或从初次冷冻解冻后6小时内从尸体上取下前肢。然后将标本冷冻不同时间，并在使用前解冻约16小时。在向预测的软组织间隙和肌筋膜间隙位置（根据前期研究数据[6只前肢]）注射不透射线的蓝色染色造影剂前后，对60只前肢的每只手部进行CT检查。两名兽医放射科医生查看CT图像，并记录每个注射部位是否存在离散间隙或间隔。随后对每只手部进行横向解剖或切片。将蓝色染色造影剂积聚的位置与CT图像中造影剂增强的位置进行比较。描述每个软组织间隙或肌筋膜间隙内的解剖结构。
在手部识别出13个软组织间隙和5个肌筋膜间隙。经检查，确定3个肌筋膜结构不是间隙。
软组织间隙和肌筋膜间隙的知识可用于绘制人类手部和足部疾病可能的传播途径。因此，了解犬手部类似结构的位置和范围可能会提高对该前肢区域有损伤或炎症的犬进行手术干预的效果。
