Is the calcaneus a weight bearing?
The posterior surface provide attachment place for the Achilles tendon; the roughed inferior surface forms the major weight bearing area of the calcaneus (Keener and Sizensky, 2005). This surface provides attachment for the plantar aponeurosis, plantar muscles and ligaments (Fig. 23.6).
Is the calcaneus bone axial?
The calcaneus axial view is part of the two view calcaneus series assessing the talocalcaneal joint and plantar aspects of the calcaneus. As technology advances, computed tomography (CT) has widely been used 1 to better visualize and characterize calcaneum fragment displacements and fracture lines.
How much do you angle for a calcaneus xray?
From this point another line is drawn to (3) – the upper edge of the anterior process of the calcaneus. Bohler’s angle is normally between 28-40 degrees.
What is calcaneus foot?
The calcaneus is the large bone at the heel of the foot. It is usually fractured after a fall from a great height or in a motor vehicle accident.
Is fibula a weight-bearing?
It is the main weight-bearing bone of the two. The fibula supports the tibia and helps stabilize the ankle and lower leg muscles. Tibia and fibula fractures are characterized as either low-energy or high-energy.
How do you use the axial view calcaneus?
- patient is supine or seated with the affected limb extended.
- the posterior aspect of the ankle is resting on the image receptor.
- foot is dorsiflexed until the plantar surface is running perpendicular to the image receptor.
What is calcaneus?
What is calcaneus Secundarius?
An os calcaneus secundarius is an accessory ossicle of the anterior calcaneal process present in up to 5% of the population at cadaveric examination. The ossicle can be a cause of ankle pain and may mimic bifurcate ligament avulsion fracture of the anterior calcaneal process.
How do you measure the angle of a calcaneal pitch?
The calcaneal inclination angle (also known as the calcaneal pitch) is drawn on a weight-bearing lateral foot radiograph between the calcaneal inclination axis and the supporting horizontal surface.
What is the calcaneus axial view?
The calcaneus axial view is part of the two view calcaneus series assessing the talocalcaneal joint and plantar aspects of the calcaneus. As technology advances, computed tomography (CT) has widely been used 1 to better visualise and characterise calcaneum fragment displacements and fracture lines.
What is a weight bearing dorsoplantar foot radiograph?
The weightbearing dorsoplantar foot radiograph is a specialized projection of the foot. Nonweightbearing views (e.g. DP foot) are inadequate for the assessment of alignment because the bones of the feet are not in a functional position.
What are the indications for calcaneus radiographs?
Calcaneus radiographs are performed for a variety of indications including: An ankle series and/or foot series may be required after the initial investigation to rule out further pathology. 1. Emergency Radiology: Imaging and Intervention. Springer. ISBN:354026227X.
What projection shows the posterior articular facet of the calcaneus?
Purpose and Structures Shown To demonstrate posterior articular facet of calcaneus to determine presence of joint involvement in cases of comminuted fracture. Anterior portion of the posterior facet is shown best in the 40-degree projection. 10-degree projection shows posterior portion.
