Aug 10, 2024 · The talus (plural: tali 4), historically known as the astragalus, is a tarsal bone in the hindfoot that articulates with the tibia, fibula, calcaneus, and navicular bones. It has no muscular attachments and around 60% of its surface is covered by articular cartilage.

Conventional Radiography is the first line methodic in the evaluation of a potential talar fracture; however CT scans with MPR and VRT reconstructions are necessary to accurately assess and classify talar fractures.

Nov 3, 2024 · Talar fractures are an uncommon injury, accounting for <5% of all foot fractures. Recognition of the unique talar anatomy is important for correct diagnosis.

The talus is a frequent site of pathology and fracture, and therefore a detailed understanding its complex anatomy is critical for accurate assessment on imaging.

Jun 18, 2024 · Talus fractures (other than neck) are rare fractures of the talus that comprise of talar body fractures, lateral process fractures, posterior process fractures, and talar head fractures. Diagnosis is made radiographically with foot radiographs but CT scan is often needed for full characterization of the fracture.

Avascular Necrosis of the Talus: A Pictorial Essay. DH Pearce, CN Mongiardi, VL Fornasier, and TR Daniels. March 2005 RadioGraphics, 25, 399-410.

Aug 27, 2024 · Computed Tomography (CT) scans are often employed when X-rays are inconclusive or when a more detailed image is needed. CT scans provide cross-sectional images of the talus, allowing for a three-dimensional assessment of the bone and any fractures.

This document outlines restor3d’s recommended CT scan parameters. restor3d does not practice medicine and is making these recommendations for optimal design of patient-specific implants, instruments, and anatomic models as necessitated by surgeon prescription.

CT Scan Most useful assessment tool for surgical planning Confirms displacement Demonstrates subtalar joint reduction, comminution, osteochondral fractures/debris

Dec 16, 2017 · Cone Beam Computed Tomography (CBCT) arthrography is better suited for precise staging of cartilage lesions. The purpose of this pictorial review is to illustrate the strength of each imaging method. Osteochondral lesions (OCL) of the talus are defined as any damage involving both articular cartilage and subchondral bone of the talar dome.
