Accessory navicular bone
The Accessory Navicular Bone (Pronunciation: ak-ses-uh-ree na-vik-yuh-lur bohn) is an extra bone or piece of cartilage located on the inner side of the foot just above the arch. It is incorporated within the posterior tibial tendon, which attaches in this area.
Etymology
The term "Accessory Navicular" is derived from the Latin words "accessorius" meaning additional, and "navicularis" meaning shaped like a ship. The term "bone" is derived from the Old English "bān".
Anatomy
An accessory navicular bone is not always present and is not part of normal skeletal anatomy. It is a congenital anomaly, meaning it is present at birth. It is located on the medial side of the foot, proximal to the navicular and continuous with the tibialis posterior tendon. It is a type of sesamoid bone, which means it is embedded within a tendon.
Clinical Significance
The accessory navicular bone can be asymptomatic, causing no problems. However, for some people, it can cause significant pain, especially when walking or participating in activities that put pressure on the foot. This condition is often referred to as Accessory Navicular Syndrome.
Treatment
Treatment for Accessory Navicular Syndrome typically begins with non-surgical approaches such as rest, ice, immobilization, and physical therapy. If these methods are unsuccessful, surgery may be considered. The surgical procedure to remove the accessory navicular bone is called a Kidner procedure.
