Cartilaginous or non-ossified sesamoid bones
may be identified on ultrasound, which can also be useful in the evaluation of adjacent soft tissue for signs of inflammation and injury (6).
The patella is an example of a sesamoid bone
, as is the navicular bone, which is in the hoof of the horse at P3.
(18) Although much less common than stress fractures, avascular necrosis of the hallux sesamoid bones
should be considered in the differential diagnosis of persistent forefoot pain.
From the 46 sesamoid bones
assessed, their width was determined to be between 34.05 mm and 50.96 mm, with an average value of 42.39 mm.

: a report of two cases," The American Journal of Surgery, vol.
fractures of metacarpophalangeal joint of thumb are very rare.
The hair over the palmar aspect of each metacarpal region was shaved, from the base of the accessory carpal bone to the base of the proximal sesamoid bones
. Cross-sectional images of normal SDFT were obtained of the palmar aspect metacarpal region of each horse using an ultrasound unit (Aloka SSD-900) with a 7.5MHz linear transducer (Aloka UST-5710-7.5), an acoustic stand-off pad (Sonokit, Sonogel Vertriebs GmbH, Alemanha) and acoustic gel (Carbogel-ULT).
Reports of stress injuries to the great toe of ballet dancers have been published, and case series have been primarily focused on stress fractures of the great toe sesamoid bones
. Currently, to the best of our knowledge, there is no known published case of stress fracture of the distal phalanx of toes, in ballet dancers or elsewhere in the population.
It reinforces the plantar capsule and also attaches the hallux sesamoid bones
to the base of the proximal phalanx (Figure 15).
Racecourse vet Peter Webbon said: 'Having been taken off the course by ambulance for further assessment, the nature of the injury to the cannon and sesamoid bones
was such that they were impossible to repair.
