The DuVries modification of the McBride procedure was investigated in 72 feet in 47 patients with hallux valgus deformity. Overall, the patient satisfaction rate was 92%. The hallux valgus averaged 32 degrees preoperatively, and 16 degrees postoperatively. The intermetatarsal angle averaged 14 degrees preoperatively and 9 degrees postoperatively. Anatomic realignment of the remaining tibial sesamoid was achieved in 28% of the feet. As a result of realignment of the first metatarsophalangeal joint, the intractable plantar keratosis beneath the second metatarsal head was resolved in 19 of 20 feet. Six patients developed a hallux varus deformity that averaged 7.5 degrees. All cases of hallux varus had medial displacement of the tibial sesamoid. The number of patients who could withstand unrestricted shoe wear increased from ten patients preoperatively to 30 patients postoperatively. The patient activity level increased in two thirds of the cases. The distal soft-tissue procedure produces the most predictable correction in patients with a hallux valgus deformity measuring less than 30 degrees. In more severe deformities, a proximal metatarsal osteotomy should be added to the procedure.
