A sesamoid is a bone, embedded within a tendon, which serves to modify pressure and alter the direction of muscle forces [2].
In an acute event, fracture margins seem relatively nonsclerotic and bone fragments generally fit together, as "pieces of a puzzle." In the bipartite sesamoid, margins become rounded and sclerotic.
Imaging studies may not be necessary in cases of suspected sesamoiditis because such studies are often negative for sesamoiditis and stress fractures of the sesamoids, and because they typically would not affect how the injury is initially treated.
lateral and dorsoplantar views of the foot and a special axial projection of the sesamoids) is initially recommended which usually present as small, well corticated, ovoid or nodular masses close to the bone surface.
The change in force distribution can lead to secondary problems in the foot, such as a soft corn, bursitis, neuroma, stress fracture of the second or third metatarsal, transfer lesion (callous formation under the head of the second metatarsal), sesamoid degeneration, achillodynia, posterior tibial tendonitis, and arthritis.
Probably the proximal center of tibia shows the preformed joint of sesamoid to tibia and in addition is a tool to reinforce the joint of quadriceps femoris muscle, too.
Stress fractures of the medial great toe sesamoids in athletes.
Chevron osteotomy does not correct pronation and only partially corrects the sesamoids. A phalangeal osteotomy can be added to improve alignment.
These marsupials may climb using claws (instead of a prehensile manus) as a response to the rigidity produced by the presence of a flexor plate with a sesamoid (the L pattern), which might preclude versatile palmar mobility (as is the case in many lizards; Virginia Abdala, personal observations).
