Abstract:

Objective-To obtain the anatomic and morphometric data required for biomechanical analysis of the hindlimb in dogs. 

Animals-A healthy adult mixed-breed 23-kg male dog. 

Procedure-Following euthanasia of the dog, all muscles of the right hind limb were identified and meticulously removed. Physiologic cross-sectional areas (PCSA) and architectural indices (Al) were calculated. The coordinates for the origin and insertion of each muscle were determined, using orthogonal 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 ofthese muscles were determined. 

Conclusions-Results provide the morphometric and anatomic data necessary for S-dimensional biomechanical studies of the hind limb in dogs.
