MSK-13 · Foot: Stress Fractures, Plantar Fasciitis, Morton, Lisfranc, and Deformities

Foot: Stress Fractures, Plantar Fasciitis, Morton, Lisfranc, and Deformities. Part of the Musculoskeletal series of the Reflex PM&R Board Review podcast. Audio corrections: (1) In the audio: with weight bearing as tolerated for four to six weeks. — Correct: A Zone 1 tuberosity avulsion is managed in a hard-soled shoe or walking boot with weight bearing as tolerated, but radiographic union averages 6 to 8 weeks (about 7 weeks in a boot and about 9 weeks in a shoe in the largest comparative series), not 4 to 6. (2) In the audio: The five sites are the femoral neck, the anterior tibial cortex, the fifth metatarsal zone, the navicular and the talus. — Correct: Those five are the most quoted, but the board-tested high-risk list also includes the patella, the medial malleolus and the great toe sesamoids: eight sites sharing high tensile load and low blood flow. (3) In the audio: there is a pathognomonic clinical finding, plantar ecchymosis. — Correct: Plantar ecchymosis after midfoot trauma is highly suggestive of a Lisfranc injury and mandates weight-bearing radiographs, but it is not pathognomonic; the diagnosis rests on the fleck sign and first-second metatarsal base widening. The written chapter is correct. Full correction register: https://www.reflexpmr.com/errata.
