Abstract
T
he use of multidetector CT with multi planar reconstruction MPR allows better visualization of fracture lines, dislocation, and comminution of calcaneal fractures, especially intraarticular fractures.
This work included 44 feet of 41 patients (three bilateral); 35 males and 6 females, representing 85.4% and 14.6% of all patients respectively, their mean age (34.22 years), lwe observed that calcaneal fractures commonly occur in male than female.
In this study multi detector CT calcaneus was done for all cases after suspecting calcaneal fracture either by clinical examination or by conventional radiography, and the patients were classified as extra and intra articular fracture according to posterior facet affection.
Involvement of the posterior facet of the subtalar joint is used to identify fracture type according to the Sanders classification system for intraarticular 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.
Extraarticular 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.
Soft-tissue involvement is an essential part of calcaneal fracture assessment because it has been linked with poor functional outcomes.
Fracture calcaneus occasionally extends anteriorly to the calcaneocuboid joint, CT images allowed to assess the degree of calcaneocuboid joint involvement before surgery.
