Ankle and Foot Conditions

Ankle valgus is a far less common deformity then ankle varus; however, these patients seem to be able to compensate better so they are likely out there but less symptomatic. Ankle valgus deformities develop more severe ankle DJD in general. The subtalar joint seems to be able to compensate for subtle deformities easier then ankle varus.
Research: Over 20,000 ankle radiographs were reviewed. Only mortise views were examined. Talocrural angles and tibial plafond position were compared with the anatomical axis of the tibia. All varus and valgus deformities were recorded that were > 5 degrees off the normal value of 89 degrees. All patients were cross-referenced with our clinical and surgical databases. Fifty-six cases of ankle valgus were identified. The valgus angulation ranged 5-24 degrees. The average was 5.2 degrees. The talocrural angle ranged from 7.4-22.6 with an average of 13.7. Only 12 of the 56 patients were seen in the clinic. Only one patient underwent ankle surgery.	Deformity of 10 degrees	More extreme deformity with very short medial malleolous
Symptomatic case which underwent surgical correction	Supramalleolar osteotomy was performed acutely and stabilized with Orthofix Sheffield Frame	Compare the two xrays. Both are standing ankle xrays. Also note that because the osteotomy occurred proximal to the actual CORA, the osteotomy needed to be translated to take into account the mechanical axis.
