Morphometric and anatomic study of the hind limb of a dog

Objective-To obtain the anatomic and morphometric data required for biomech anical analysis of the hind limb in dogs. Animals-A healthy adult mixed-breed 23-kg male dog. Procedure-Following euthanasia of the dog, all muscles of the right hind li mb were identified and meticulously removed. Physiologic cross-sectional ar eas (PCSA) and architectural indices (Al) were calculated. The coordinates for the origin and insertion of each muscle were determined, using orthogon al right-handed coordinate systems embedded in the pelvis, femur, and tibia . Results-PCSA and Al were calculated for 29 muscles, and coordinates for the origins and insertions of these muscles were determined. Conclusions-Results provide the morphometric and anatomic data necessary fo r S-dimensional biomechanical studies of the hind limb in dogs.
