Idiopathic anterior pes cavus and its surgical treatment

Abstract

19 feet of 15 patients who were operated for idiopathic anterior pes cavus between 1975 and 1988 were evaluated. The average follow-up was 4. 6 years. The procedures that were pertormed as primary procedures were as follows; anterior dorsal wedge osteotomy in 8 feet (42.1%). triple arthrodesis in 5 feet (26.3 %). Japas (tarsal V'' osteotomy) in 4 feet (12. 1 %). and Dwyer osteotomy in 2 patients (10.5%) with calcaneovarus deformity. Secondary deformities such as contracture of the Achilles tendon, hammer toe deformities and contracture of plantar fascia were also corrected. The results were evaluated according to the Massachusetts General Hospital criteria. There were anatomically 73.7% and functionally 68.4% good to excellent results. We think that satisfactory results can be obtained with anterior dorsal wedge osteotomy at the apex of the deformity (with additional sott tissue procedures) provided that the joints without functional and arthritic changes are protected.
