Sesamoiditis (Subscribe)  

Athletic foot injuries can be difficult to properly diagnose and treat. Bearing the weight of the entire body, the foot is under tremendous stress. In many sports, the foot absorbs tremendous shearing and loading forces, sometimes reaching over 20 times the person's body weight. Physicians who treat these disorders must...

From Applied Radiology Appl Radiol. 2007;36(10):28-37. Accessory Ossicles and Sesamoid Bones: Spectrum of Pathology and Imaging Evaluation Dr. Kalantari; Dr. Seeger; Dr. Chow; Dr. Motamedi Author Information Abstract (full text avaialble)
The authors describe a spectrum of accessory ossicle and sesamoid pathology and suggest appropriate imaging modalities. While they are considered to be normal...

The hallux sesamoids can be associated with acute or stress fractures. 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. The tibial sesamoid is more likely to fracture than the fibular sesamoid because of...

Part of a page describing injuries in dancers.
The sesamoids provide a support surface while the dancer is on demi-pointe. The tendon that runs between the sesamoids can become inflamed, causing sesamoiditis, a form of tendinitis. Pain is focused under the big toe on the ball of the foot. With sesamoiditis,...

Two pea-sized bones, called sesamoids, are embedded within the soft tissues under the main joint of the big toe. Even though they are small in size, the sesamoids play an important role in how the foot and big toe work. If the sesamoids are injured, they...

Discussion of anatomy, function, consequences of excision, radiographs and patho-anatomy

Discussion notes, differential diagnosis, radiographs, acute treatment, treatment of stress fractures and excision of sesamoids

Pain related to the great toe sesamoids is uncommon in a general foot and ankle practice, but may be commoner where there is a large sports medicine component to the practice.
The hallux MTP sesamoids are embedded in the tendons of flexor hallucis brevis. They are subjected to the stresses of...

Sesamoid bones are commonly found in and around joints. While sesamoid bones can be found around any joint in the foot, they are consistently found within the joint of the great toe. The great toe joint contains 2 sesamoid bones, the tibial and fibular sesamoids.

Sesamoiditis is an inflammatory condition of the sesamoid bones which are located on the plantar (bottom) aspect of the first metatarsal phalangeal joint (1st MPJ or big toe joint). Sesamoiditis occurs at the articulation or joint found between the sesamoid and the overlying 1st metatarsal. Sesamoiditis is usually... Uncertain

inflammation and swelling around the sesamoid (tibial> fibular) and FHB can be secondary to trauma, infection, AVN, stress fractures, or a systemic disorder;
- sesamoiditis may also be precipitated by a cavus foot w/ excessive wt bearing under the...
