Calcaneal fractures are categorized into two types : Intra-and Extrarticular fractures on the basis of subtalar joint involvement.
12.
The plantar fascia is a broad structure that spans between the medial calcaneal tubercle and the proximal phalanges of the toes.
13.
On the lateral side is commonly a tubercle called the "'calcaneal tubercle "'( or trochlear process ).
14.
In addition, footwear can create an impact on the forces that may cause a calcaneal fracture and can prevent them as well.
15.
A projection on the calcaneum bone called the calcaneal tuber is narrow and positioned downward relative to other lateral projections on the bone.
16.
Other morphologies include skeletal and anterior dentition, such as wrist and ankle apomorphies; all metatherians share derived pedal characters and calcaneal features.
17.
Radiography has little role in assessment of Achilles'tendon injury and is more useful for ruling out other injuries such as calcaneal fractures.
18.
A "'posterior calcaneal spur "'develops on the back of the heel at the insertion of the Achilles tendon.
19.
The two most common types of tarsal coalitions are calcaneo-navicular and talo-calcaneal, comprising 90 % of all tarsal coalitions.
20.
The Angle of Gissane, or " Critical Angle ", is the angle formed by the downward and upward slopes of the calcaneal superior surface.
