    Abstract:
    The importance of correction of the high proximal articular set angle with a subluxed joint in hallux abducto valgus for long-term correction is cited. I have shown that if the laterally deviated facet is not corrected, pronatory forces continue to act on the first ray. When force is applied to a still laterally tilted first metatarsophalangeal joint, further side-slipping of the joint will occur even though modification of the Silver, McBride, or osteotomy procedures of the first metatarsal have been performed successfully. A review of the standard procedures for the correction of a high proximal set angle alone usually did not correct the high intermetatarsal angle usually associated with this problem. Combination procedures sometimes created complications. These include dorsal dislocation of the distal fragment in correction of the sagittal plane deformity causing metatarsalgia, limited dorsal range of motion, and damage to the sesamoids or sesamoid grooves on the plantar aspect of the first metatarsal. Angulational transpositional derotation and hallux set (ATDH) is offered to correct four deformities using one or two 1-cm incisions together with "stab" incisions. This method overcomes the many disadvantages of previous procedures and can be used in the presence of biomechanical pronatory forces to reduce the proximal articular set and intermetatarsal angles; to derotate the hallux; to neutralize the forces that pull the proximal phalanx off the first metatarsal head; and if necessary, to correct the sagittal plane deformity of the first metatarsal so that weight bearing is not disturbed.(ABSTRACT TRUNCATED AT 250 WORDS)
