To diagnose accessory navicular syndrome, the foot and ankle surgeon will ask about symptoms and examine the foot, looking for skin irritation or swelling. The doctor may press on the bony prominence to assess the area for discomfort. Foot structure, muscle strength, joint motion and the way the patient walks may also be evaluated.
Projectional radiography, also known as conventional radiography, [1] is a form of radiography and medical imaging that produces two-dimensional images by X-ray radiation.The image acquisition is generally performed by radiographers, and the images are often examined by radiologists.
On the lateral side, the implant should be observed resting on the floor of the sinus tarsi. [13] In cases where deformities are present in both feet, bilateral arthroereisis can be performed. Dorsiflexion of the foot is accomplished with the knee extended post surgical repair.
Weight-bearing lateral X-ray showing the measurement of calcaneal pitch, which is an angle of the calcaneus and the inferior aspect of the foot, with different sources giving different reference points. [18] Calcaneal pitch is increased in pes cavus, with cutoffs ranging from 20° to 32°. [17]
Calcaneal spurs are typically detected by x-ray examination. [2] It is a form of exostosis. When a foot is exposed to constant stress, calcium deposits build up on the bottom of the heel bone. Generally, this has no effect on a person's daily life.
There are three x-ray views in a complete ankle series: anteroposterior (AP), lateral, and oblique (or "mortise view"). The mortise view is an AP x-ray taken with the ankle internally rotated 15-20 degrees since the foot is naturally externally rotated relative to the ankle. [9]
Same lateral X-ray showing the measurement of Meary's angle, which is the angle between the long axis of the talus and first metatarsal bone. [11] An angle greater than 4° convex downward is considered a flat foot, 15° - 30° moderate flat foot, and greater than 30° severe flat foot. [11]
The Angle of Gissane, or "Critical Angle", is the angle formed by the downward and upward slopes of the calcaneal superior surface. On a lateral radiograph, an angle of Gissane > 130° suggests fracture of the posterior subtalar joint surface. Böhler's angle, or the "Tuber Angle", is another normal anatomic landmark seen in lateral radiographs.
