What does OS Tibiale Externum mean?

What happens after accessory navicular surgery?
In most instances, a patient’s recovery will be as follows: 0-6 weeks: Immobilization (in cast or cast boot) non-weight-bearing or touch weight-bearing. 6-10 weeks: Increasing activity in a cast boot. Physical therapy to work on strength and balance.
What causes the navicular bone to stick out?
This can result from any of the following: Trauma, as in a foot or ankle sprain. Chronic irritation from shoes or other footwear rubbing against the extra bone. Excessive activity or overuse.
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 rare?
