Computed tomography of the calcaneus: normal anatomy

Area of Science:

• Orthopedic imaging
• Radiology
• Anatomy

Background:

• Accurate interpretation of calcaneus fractures relies on understanding normal anatomy.
• Computed tomography (CT) is a key imaging modality for calcaneus fractures.

Purpose of the Study:

• To describe the normal sectional anatomy of the calcaneus.
• To provide a background for interpreting CT scans of calcaneus fractures.

Main Methods:

• Multiplanar CT examination of the normal calcaneus was performed.
• Sections were correlated with a simplified anatomic model.

Main Results:

• The sectional anatomy in four key planes was described.
• A three-dimensional understanding of the calcaneus was facilitated.

Conclusions:

• This anatomical description aids in the interpretation of CT sections of the calcaneus.
• It improves the understanding of calcaneus fractures on CT, even in atypical planes.
