Os tibiale externum sagittal T2 YouTube
The os tibiale externum is also known as accessory navicular bone, os naviculare secundarium, accessory (tarsal) scaphoid, or prehallux. It is found within the tibialis posterior tendon near its insertion on the navicular bone. The os peroneum is a small sesamoid bone located within the peroneus longus tendon, adjacent to the cuboid.

For e.g., the accessory navicular bone is also known as tibiale externum, prehallux, os supranavicular, talonaviculare ossicle, and Pirie's bone [ 2 ].

An accessory bone or supernumerary bone is a bone that is not normally present in the body, but can be found as a variant in a significant number of people. It poses a risk of being misdiagnosed as bone fractures on radiography. [2] Wrist and hand [ edit] X-ray of the wrist, with most common accessory bones labeled. [3]

The accessory navicular—also known as the os naviculare or os tibiale externum—is a small bone that extends from the navicular bone, one of the tarsal bones near the instep. About 14 percent of the population has an accessory navicular, and about half of the people with the extra bone have it in both feet.

Its prevalence is approximately 30% and represents the classically known os tibiale externum. Type I accessory navicular are usually asymptomatic (Fig. 2). Interestingly, the os tibiale externum has been commonly described as a sesamoid in the literature [3-7], which represents a different concept from an accessory ossicle. The distinction.

Accessory navicular. The accessory navicular is also known as the os tibiale, os tibiale externum, or naviculare secundarium. Estimated prevalence has been set in between 4 and 21% [1,2,3].A recent long series by Kalbouneh et al. estimates it as 20.9% [].The accessory navicular is located adjacent to the postero-medial tuberosity of the bone, and three different configurations exist [].
Treating The Accessory Navicular In Young Athletes
Also known as 'os tibiale externum' or 'os navicularum', accessory navicular syndrome refers to a congenital abnormality related to the growth of an extra bone within the foot. This additional piece of bone is not present in a normal human foot and grows toward the middle inner part of the foot near the navicular bone.

The accessory navicular (os navicularum or os tibiale externum) 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 and can lead to Accessory Navicular Syndrome. An accessory navicular is congenital (present at birth).
Os tibiale externum Image
Os tibiale externum (OTE) also termed accessory navicular, os naviculare, or os navicularis is a common accessory bone in the foot located medial and sometimes proximal to the navicular tuberosity. It is attached and continuous with the tibialis posterior tendon and is present in 10 to 15% of the population either unilateral or bilateral.

Type I is a 2-3 mm sized sesamoid bone, also referred to as os tibiale externum and is located at the level of the inferior calcaneonavicular ligament within the tibialis posterior tendon. Type II is an accessory bone, also referred to as prehallux , connected to the navicular by a fibrocartilage or hyaline cartilage (synchondrosis).

Type 1: An os tibiale externum is a 2-3 mm sesamoid bone in the distal posterior tibialis tendon. Usually asymptomatic. Type 2: Triangular or heart-shaped ossicle measuring up to 12 mm, which represents a secondary ossification center connected to the navicular tuberosity by a 1-2 mm layer of fibrocartilage or hyaline cartilage.

Os tibiale externum (accessory navicular) is a large ossicle adjacent to the medial side of the navicular bone. The tibialis posterior tendon often inserts with a broad attachment onto the ossicle, which may cause a painful tendinosis due traction between the ossicle and the navicular. Such changes are best seen on MRI. Credit: Dr Donna D'Souza.
