Background
The calcaneus acts as the critical foundation upon which the human skeleton functions, and as such it is the site of many unique pathologies and abnormalities. This spectrum encompasses traumatic, congenital, and infectious anomalies as well as non-pathologic variations. Recognizing and understanding normal and pathological conditions in the calcaneus can be the key to getting patients back on their feet.

Educational Goals / Teaching Points
This exhibit will include a review of anatomy, as well as normal and benign variants, with demonstrations of focal and systemic conditions that may affect the calcaneus. There will be a multi-modality discussion of findings with radiography, CT and MRI. For indeterminate lesions, a differential diagnosis and suggestions on further evaluation will be provided.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
Benign findings and normal variations such as pseudolesions and vascular remnants will be discussed. Calcaneal anatomic variants and their potential symptoms will be reviewed including calcaneal coalition, the peroneal tubercle and the retrotrochlear eminence. Traumatic injuries will cover avulsion fractures, complex and stress fractures with the key findings related to surgical intervention highlighted. Chronic repetitive injuries of plantar fasciitis and Haglund deformity. Heel ulcerations and resultant osteomyelitis will be reviewed as well as calcaneal neoplasms including lipomas and aneurysmal bone cysts.

Conclusion
Detecting and differentiating the multitude of calcaneal findings is critical to achieving positive clinical results. After reviewing the exhibit, an observer should understand the key imaging findings related to each of the discussed diagnoses and be prepared to communicate relevant information to clinicians.
