A 45-year-old woman undergoes surgical treatment for hallux valgus. One year later she presents with the painless foot deformity shown in Figure A. All of the following variables can lead to the development of this deformity EXCEPT:
Resection of the fibular sesamoid
Resection of the tibial sesamoid
Avascular necrosis (AVN) of the first metatarsal head secondary to a distal osteotomy
Excessive postoperative bandaging
Excessive medial capsular reefing

The procedure shown in Figure A would be most appropriate for which of the following scenarios?
HVA = 10, IMA = 6, DMAA= 7, congruent joint
HVA = 40, IMA = 20, DMAA = 8, advanced MTP arthritic changes
HVA = 20, IMA = 10, DMAA = 20, congruent joint
HVA = 16, IMA = 12, DMAA = 14, congruent joint, TMT hyper-mobility
HVA = 18, IMA = 12, DMAA = 9, congruent joint
A 47-year-old female presents with persistent left great toe pain. Two years prior, she underwent hallux valgus corrective surgery with a Chevron osteotomy. Figure A exhibits her most recent radiograph. What is the most likely diagnosis and appropriate treatment?
Post-traumatic arthritis of the metatarsal head and MTP arthrodesis
Osteonecrosis of the metatarsal head and intraarticular osteotomy
Osteonecrosis of the metatarsal head and MTP arthrodesis
Hallux varus and lateral capsular imbrication
Hallux valgus recurrence and conservative management
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?
Keller resection arthroplasty
Distal first metatarsal osteotomy (Chevron) with lateral metatarsophalangeal joint soft-tissue release (modified Mcbride)
Proximal first metatarsal osteotomy (Scarf) with lateral metatarsophalangeal joint soft-tissue release (modified Mcbride)
Metatarsal cuneiform fusion (Lapidus) with lateral metatarsophalangeal joint soft-tissue release (modified Mcbride)
Lateral metatarsophalangeal joint soft-tissue release (modified Mcbride)
A 47-year-old woman that works as an attorney has a 3-year history of bilateral painful forefeet that is exacerbated with the dress shoes she wears for work. Physical examination reveals bursal inflammation and calluses at the medial eminence of the first metatarsal with a 1st metatarsalphalangeal (MTP)joint 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 23 degrees and the intermetatarsal angle (IMA) is measured at 12 degrees. Which of the following surgical interventions is most appropriate for correction of her deformities?
Distal metatarsal osteotomy (Chevron)
Closing wedge osteotomy of the proximal phalanx (Akin) combined with distal soft tissue release (Modified Mcbride)
Resection of medial eminence (Silver bunionectomy)
Proximal metatarsal osteotomy and first MTP arthrodesis
Metatarsal cuneiform fusion (Lapidus)
A 57-year-old administrative assistant complains of pain over the bunion on her right foot. Physical exam is notable for tenderness over the medial prominence of the first metatarsophalangeal joint and hypermobility of the first ray. Shoe modifications have failed to provide relief. A clinical photograph and radiograph are provided in figures A and B. Surgical treatment with metatarsocuneiform arthrodesis is chosen. Each of the following are associated with a better clinical outcome EXCEPT:
Multiple screw fixation across the metatarsocuneiform arthrodesis
Augmentation of the metatarsocuneiform arthrodesis with bone grafting
Dorsiflexion unloading of the first metatarsal
Correction of the first intermetatarsal angle
Failure of conservative treatments prior to surgery
A 67-year old female presents with the bilateral foot deformity shown in Figures A and B. All of the following contribute to the risk of recurrence after surgery EXCEPT:
Resection of the lateral sesamoid
Lack of lateral capsular release
Lack of medial metatarsophalangeal joint capsule closure
Use of an Akin procedure alone for a moderate to severe deformity
Undercorrection of the widened 1-2 intermetatarsal (IMA) angle
A 57-year-old female underwent surgery for severe hallux rigidus. Postoperative radiographs are shown in Figure A. One year later she complains of pain at the 2nd metatarsal head and her exam shows a plantar callosity under the 2nd metatarsal head. What procedure could have been combined with her initial operation to prevent this outcome?
Second metatarsalphalangeal joint arthrodesis
Second metatarsal osteotomy (Weil) with extensor tendon and dorsal capsular release
Flexor to extensor tendon transfer (Girdlestone-Taylor)
Second metatarsal osteotomy (Helal) with extensor tendon and dorsal capsular release
Second metatarsal head resection with extensor tendon and dorsal capsular release
