Abstract
We report a case of valgus ankle degenerative arthritis due to chronic isolated deltoid insufficiency combined with tibial varus that was treated successfully with ankle joint preserving surgery. A 63-year-old male complained of right lateral ankle pain with 10 minutes of maximal pain-free walking time. The assessed American Orthopaedic Foot and Ankle ankle-hindfoot scale score was 33 points. The ankle joint showed 18° of valgus deformity with 6° of tibia varus. Medial displacement calcaneal osteotomy, supramalleolar open wedge osteotomy, and deltoid ligament imbrication were performed. At the 2-year follow-up examination, the ankle joint showed 10° of valgus and the tibial plafond showed flattening. The hindfoot showed 7° of valgus. He could run for 2 hours on the treadmill without pain. The American Orthopaedic Foot and Ankle ankle-hindfoot scale score was 90 points. In conclusion, valgus ankle degenerative arthritis with isolated deltoid insufficiency and tibial varus could be treated successfully with realignment using a double osteotomy and additional deltoid imbrication.
