A 53-year-old woman has had progressive hallux valgus deformity of her right great toe for the last 12 years. She has failed nonoperative management including shoe modifications and padded inserts. Her surgeon recommends a Lapidus procedure (1st metatarsal cuneiform arthrodesis). Which of the following is an indication for this procedure?

Hallux valgus angle: 40°
Age > 50-years-old
Flexible cavovarus deformity
1st tarsometatarsal arthritis
A 65-year-old female presents with persistent pain in the left great toe. She is interested in surgery as she has been seeing a podiatrist for many years who had prescribed wider shoewear and an unknown kind of orthotic. Her exam shows pes planus which reconstitutes with heel raise, calluses under the first MTP. The 1st TMT joint shows excessive passive plantar and dorsiflexion. While examining the rest of the lower extremity, both knees are able to hyperextend to about 15 degrees but show no other malalignment. Additionally, she shows she is able to reproduce the finding shown in Figure A. Her current radiographs are shown in Figure B. What is the best surgical option to address her deformity?
Double metatarsal osteotomy with sesamoidectomy
Double metatarsal osteotomy with modified McBride
Metatarsophalangeal joint arthrodesis with modified McBride
Modified McBride with Akin osteotomy
Tarsometatarsal joint arthrodesis with modified McBride
Which of the following pre-operative measurements would call for a surgical plan involving both a proximal 1st metatarsal osteotomy and a distal-medial closing wedge osteotomy?

HVA 45, IMA 12, HVI 8, DMAA 8
HVA 30, IMA 16, HVI 8, DMAA 16
HVA 45, IMA 16, HVI 14, incongruent MTP

A 38-year-old woman has a 2-year history of left greater than right foot pain. Physical examination demonstrates full 1st metatarsalphalangeal (MTP)joint dorsiflexion and plantarflexion with a deformity that passively corrects. A clinical image is shown in Figure A and a radiograph is shown in Figure B. The hallux valgus angle (HVA) is measured at 31 degrees and the intermetarsal angle(IMA) is measured at 16 degrees. Which of the following surgical interventions is most appropriate for correction of her deformities?
