A New Z-Shaped Calcaneal Osteotomy for 3-Plane Correction of Severe Varus Deformity of the Hindfoot

Surgical treatment of varus hindfoot deformity may necessitate bony and soft-tissue corrections, as it is often associated with a cavovarus deformity of the foot. Different procedures have been suggested; most of the authors, however, recommend a calcaneal osteotomy to address the varus deviation of the heel, particularly if a rigid deformity is present. The popular Dwyer osteotomy shortens the heel and allows only limited correction in only 1 plane, and therefore, several modifications of the classic Dwyer osteotomy have been described. This article describes an attractive alternative procedure with a Scarf-like osteotomy, allowing to correct the heel in a frontal and transversal plane.
