Some clinical and other observations are made on cavus deformity of the foot, and a new surgical procedure is presented for the correction of anterior pes cavus. This procedure includes fasciotomy in the sole according to the technique of Steindler and a V-osteotomy of the tarsus that permits the correction of deformity at the most prominent point without the disadvantages of the classic techniques (shortening of the foot, delay in consolidation, and interference with tarsal motion). The results in seventeen feet followed for from two to six years have been encouraging.
