Flashcards in Foot Anomalies Deck (10):
Congenital fibrous or bony union of the tarsal bones
The two most common tarsal coalitions are:
Calcaneonavicular (50%), and talocalcaneal (35%)
What radiographic view is best for visualizing calcaneonavicular coalition?
Medial oblique ankle
What is a tell-tale sign of talocalcaneal coalition on a lateral ankle radiograph?
The 1st metatarsal bone is short relative to the 2nd
Failure of union of the secondary growth center at the posterior talus, resulting in a fragment of bone. May produce posterior ankle pain on plantar flexion
Secondary ossification center of the medial navicular. Has 3 types
Accessory Navicular (Os tibiale externum)
Accessory ossicle between first and second metatarsal
An ossicle near the cuboid bone (posterior to it)
