What does accessory ossicle mean?
Accessory ossicles are well-corticated bony structures found close to bones or a joint. They result from unfused ossification centres and are frequently congenital. They may, however, also be the result of prior trauma.
How do you treat accessory ossicles?
These ossicles are not usually a problem but can become irritable with injury to the foot. Treatment can include rest, ice , elevation, and immobilization. This usually requires a boot extending up to the knee. The treatment period may require several weeks to achieve complete healing.
What is an ossicle in foot?
Ossicles are small bones. The ossicles which occur in the ankle are accessory ossicles – extra bones which form naturally during the development of the skeleton.

What is an accessory ossicle of the knee?
This accessory ossicle is typically found in the lateral head of gastrocnemius, as a sesamoid bone in the posterolateral capsule of the knee joint (Figure 2). Occasionally they are found in the medial head of gastrocnemius. Fibrocartilaginous in nature, they can articulate with the respective femoral condyle.
How common are accessory bones?

What is the function of accessory bone?
Their function is to protect the tendon from injury by reducing friction. In contrast, accessory ossicles are supernumerary bones that commonly derive from unfused primary or secondary ossification centres [1]. They are thought to be normal variants with no definite known function.
Are ossicles painful?
Accessory ossicles usually remain asymptomatic, but can become painful due to fractures, dislocations, degenerative changes, osteonecrosis, osteoarthritis, osteochondrial lesions, avascular necrosis, tumors, and irritation or impingement of adjacent soft tissues.

What is an accessory navicular ossicle?
An accessory navicular is a large accessory ossicle that can be present adjacent to the medial side of the navicular bone. The accessory navicular bone presents as a sesamoid in the posterior tibial tendon, in articulation with the navicular or as an enlargement of the navicular itself.
How do you treat an extra bone in your foot?
Nonsurgical Treatment Approaches
- Immobilization. Placing the foot in a cast or removable walking boot allows the affected area to rest and decreases the inflammation.
- Ice. To reduce swelling, a bag of ice covered with a thin towel is applied to the affected area.
- Medications.
- Physical therapy.
- Orthotic devices.
