Bulbar part of digital cushion
Pars torica pulvini digitalis
Definition
The bulbar part of the digital cushion is the caudal, rounded portion of the digital cushion located beneath the bulbs of the heel (the bulbs of the frog) in the equine hoof.
It forms a fibro-elastic (often fibro-fatty) shock-absorbing mass that supports the heel region and contributes to the hoof’s deformation and energy dissipation during weight bearing.
