[Patellar dimensions related to canine body mass for use in the manufacture of prosthesis: cadaver study]

ABSTRACT The aim of this study was to measure the canine cadaver patellar dimensions and evaluate its relationship with body mass. 70 cadavers of adult dogs were used, with a body mass between 1 and 50kg, without clinical evidence of affection in the stifle joint. The external and internal lengths, external width in the middle third, width and thickness of the proximal, middle and distal thirds were measured using a pachymeter. The width was also measured in the proximal third, middle third and distal third, depth in the proximal third, middle third and distal third of the trochlear groove; these measurements were exclusively internal. A strong correlation was observed between the patellar dimension and body mass of canine cadavers. Under this study conditions, it is possible to conclude that the patellar size varies according to the canine body mass and these measures should be considered when planning a prosthetic replacement.

摘要 本研究旨在测量犬尸体髌骨的尺寸，并评估其与体重的相关性。本研究选取70具成年犬尸体，其体重介于1至50千克之间，且膝关节无临床可见的病变征象。使用测厚仪测量了髌骨的内外长度、中1/3段的外宽度，以及髌骨近段、中段和远段1/3的宽度与厚度。此外，还测量了滑车沟近段、中段和远段1/3的宽度，以及滑车沟同三段的深度；上述测量均为内部测量。研究结果显示，犬尸体的髌骨尺寸与体重之间存在显著的强相关性。在本研究的实验条件下，可得出结论：犬髌骨尺寸随其体重变化而改变，因此在规划假体置换手术时应考虑此类测量数据。
