1. The document discusses various surgical procedures for correcting hallux valgus deformity, including distal soft tissue procedures, osteotomies of the first metatarsal, and phalangeal osteotomies.
2. Common procedures described are the modified McBride bunionectomy, Mitchell osteotomy, Chevron osteotomy, and Ludloff osteotomy.
3. Patient factors like age, severity of deformity, and joint arthritis help determine which procedure is most appropriate. Soft tissue procedures are preferred for milder cases while more severe deformities may require metatarsal osteotomies.
16. first variant , the articular surface of the metatarsal head is offset, resembling a scoop of ice cream sitting at an angle on a cone This has been described as the distal metatarsal articular angle Second variant the articular angle of the base of the proximal phalanx in relation to its longitudinal axis is offset. This has been described as the phalangeal articular angle
