“…Osteoarthritis may affect any joint in the mid-to forefoot, but it most commonly involves the joints of the medial longitudinal arch. The medial column, which is composed of the 1 st MTP joint, or middle column, which comprises the 2 nd and 3 rd MTP joints, are usually affected more than the lateral column, which includes the 4 th and 5 th MTP joints (30) . Patients present with pain aggravated by prolonged weight-bearing.…”

“…US reveals joint space narrowing with marginal osteophytosis, capsular thickening, and mild surrounding soft tissue swelling, possibly with hyperemia on Doppler imaging (Fig. 26) (30) . As the curvature of the articular surfaces and marginal osteophytosis limits accurate US assessment of joint space narrowing, radiographic correlation is useful in this regard.…”

“…If surgery is considered, CT optimizes delineation of osseous anatomy, disease extent, and severity, as well as alignment. Cone beam CT is a small footprint, self-shielded device, producing high-quality localized CT images of the mid-and forefoot, and is a useful emerging imaging modality for foot osteoarthritis, not least that the examination can be obtained in the weightbearing position (30) . MRI is advantageous in showing subchondral BME, which is moderately associated with pain with or without focal articular cartilage defects.…”

Radiography is the appropriate initial imaging modality to assess for midfoot and forefoot pathology before turning to advanced imaging techniques. While most lesions of the mid- and forefoot can be diagnosed clinically, the exact nature and severity of the pathology is often unclear. This review addresses the use of the ultrasound, as well as the added value of magnetic resonance imaging, in diagnosing conditions of the mid- foot and forefoot. Ultrasound allows a dynamic assessment as well as enabling imaging-guided interven- tions for diagnostic and therapeutic purposes. Practical tips for optimal examination of this area with ultra- sound and magnetic resonance imaging are provided. Metatarsal stress fracture, Chopart’s injury, Lisfranc injury, as well as the 1st metatarsophalangeal joint injury and lesser metatarsophalangeal plantar plate injury are injuries unique to the mid- and forefoot. The imaging anatomy of the 1st and lesser metatarsophalan- geal joints is reviewed, as such knowledge is key to correctly assessing injury of these joints. Characteristic imaging features of masses commonly encountered in the mid- and forefoot, such as ganglion cyst, Morton neuroma, gouty tophus, plantar fibroma, foreign body granuloma, and leiomyoma are reviewed. The use of ultrasound and magnetic resonance imaging in assessing degenerative and inflammatory joint disorders, and in particular rheumatoid arthritis, of the mid- and forefoot region is also reviewed. In summary, when necessary, most lesions of the mid-and forefoot can be adequately assessed with ultrasound, supplemented on occasion with radiographs, computed tomography, or magnetic resonance imaging.
