Vague pain or throbbing in the midfoot and arch, usually occurring during or after periods of activity.
How long does it take to recover from accessory navicular surgery?
After 6 weeks, most patients can bear their full weight on the foot and start physical therapy, returning to their normal foot function after about 6 months of rehabilitation.
What is an OS Naviculare?
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. An accessory navicular is congenital (present at birth).
What percent of the population has accessory navicular syndrome?
An accessory navicular is an extra bone that is on the inner center arch of the foot. Up to 2.5 percent of individuals are born with the accessory navicular.
How successful is accessory navicular surgery?
Conclusions: When conservative measures fail to relieve the symptoms of a painful accessory navicular, simple excision of the accessory navicular and anatomic repair of the posterior tibialis tendon is a successful intervention. Overall, the procedure provides reliable pain relief and patient satisfaction.
What is Type 2 OS Naviculare?
Type II is a secondary ossification center of the navicular bone and is also referred to as “prehallux”, accounting for approximately 50-60% of accessory navicular bones. It is seen over the medial pole of the navicular bone at between nine and 11 years of age (3).
Is accessory navicular syndrome rare?
In summary, an accessory navicular is a fairly uncommon condition which is rarely symptomatic. Oftentimes nonsurgical treatment is successful. In the minority of cases, surgical intervention is required.
What is Type 2 Naviculare?
Where does the name OS naviculare pedis come from?
Its name (os naviculare pedis; scaphoid bone) derives from the human bone’s resemblance to a small boat. It articulates with four bones: the talus and the three cuneiforms; occasionally with a fifth, the cuboid. While rare in the general population, stress fractures of the tarsal navicular bone are frequently incurred by professional athletes.
Are there any stress fractures in the navicular bone?
While rare in the general population, stress fractures of the tarsal navicular bone are frequently incurred by professional athletes. The navicular unique anatomic location subjects it to medial and lateral compression forces from the first and second meta-tarso-cuneiform joints, respectively.
Where is the accessory navicularum located in the foot?
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.
What causes pain in the accessory navicular bone?
An accessory navicular bone may be present in individuals young and old. Athletes may find this condition to be painful over the inner aspect of the arch of the foot. The pain can occur in an acute setting from a traumatic injury that disrupts the connection between the accessory navicular and the adjacent bone.
