Abstract
Multi detector CT allow better visualization of
fracture lines, dislocation, and comminution of calcaneal
fractures, especially intraarticular fractures. Involvement
of the posterior facet of the subtalar joint is used to
identify fracture type according to the Sanders
classification system for intra articular fractures, which
represent the majority of calcaneal fractures. The
Sanders system has proved useful, having been shown to
correlate with management and prognosis, without
significant interobserver variability. Extra articular
fractures include all fractures that do not involve the
posterior facet, and they are classified on the basis of
their anatomic location on the anterior process, body, or
posterior tuberosity of the calcaneus.
Bohler’s angle is an important parameter in the
assessment and diagnosis of the Calcaneal fracture, It
normally measures between 20o and 40o degrees, if an angle of Bohler less than 20° indicates posterior facet
collapse from an underlying calcaneal fracture.
Fracture calcaneus occasionally extends anteriorly
to the calcaneocuboid joint, CT images allowed to
assess the degree of calcaneocuboid joint involvement
before surgery.
Radiologists must be familiar with injuries of the
calcaneus, their anatomy, mechanisms, classification,
and implications to help guide the treating physicians.
