Radiologic and anatomic observations of plantar sesamoid bones at the tarsometatarsal articulations of greyhounds.
In Greyhounds, 2 plantar sesamoid bones were identified in radiographs taken of the intact tarsus and also of the tarsometatarsal fibrocartilage, that had been dissected free from the joints. Anatomic dissections defined the precise position of each sesamoid. A prominent sesamoid was present on the lateral side of the tarsometatarsal articulation in 50% of the tarsi; it is proposed that this bone be named the lateral plantar tarsometatarsal sesamoid bone. A smaller bone was detected on the medial side of the tarsometatarsal articulation in 27% of the tarsi; it is proposed that this bone be named the intra-articular tarsometatarsal sesamoid bone.
