Purpose or Case Report: In the second part of this exhibit, congenital bone anomalies of the lower extremity will be identified and reviewed. Through this exhibit, the reader will be able to: 1. Define the most common entities encompassing congenital lower extremity bone anomalies based on classic clinical presentation and demographics. 2. Highlight key multi-modality imaging characteristics to accurately differentiate between the various congenital bone anomalies of the lower extremity.
Methods & Materials: Patients with congenital lower extremity bone anomalies encountered in our institution were reviewed and selected to highlight pertinent clinical and radiologic features that are associated with each anomaly. Key imaging findings unique to each of these conditions will be highlighted.
Results: Multiple congenital bone anomalies of the lower extremity will be described based on clinical presentation and key imaging characteristics. These entities include: Proximal Focal Femoral Deficiency, Fibular Hemimelia, Tibial Hemimelia, Tarsal Coalition, Femoral Duplication, Achondroplasia, Split Hand-Foot Malformation, Coxa Valga, Tibial Bowing, Constriction/Amniotic Bands, and Developmental Dysplasia of the Hip.
Conclusions: The goal of this two-part exhibit is to highlight key imaging findings unique to each of these conditions to allow for efficient and accurate differentiation. This will provide a high yield approach to simplifying the diagnosis based on clinical presentation, demographics and imaging findings.
