Soft tissue masses may be encountered in the foot and ankle and may represent true neoplasms, malignant or benign, or other, nonneoplastic entities that mimic musculoskeletal tumors. This article reviews…
Impingement is a clinical syndrome of chronic pain and restricted range of movement caused by compression of abnormal bone or soft tissue within the ankle joint. It usually occurs following…
The metatarsophalangeal (MTP) joint complex is a weight-bearing structure important to the biomechanics of the standing position, walking, shoe wearing, and sport participation. Acute dorsiflexion injury of the first MTP…
Following a brief description of the normal anatomy and biomechanics of the midfoot, this article focuses on MR imaging features of common osseous, tendon, and ligament abnormalities that affect the…
Heel pain is common and due to a variety of osseous and soft tissue disorders. Causes of heel pain can be classified by the anatomic structure in which they arise…
Abnormalities of the medial ligaments and posterior tibial tendon can occur because of acute injury or chronic instability or malalignment. Medial ankle injuries may occur because of pronation or supination–external…
MR imaging is ideally suited for characterization of the soft tissue, cartilaginous, and osseous structures of the pediatric ankle. An understanding of the normal MR imaging appearance associated with the…
Acute and chronic ankle inversion injuries are a common source of pain and a diagnostic challenge. Several studies have shown a variety of injury patterns after inversion injury both in…
Accessory muscles around the ankle are commonly encountered as incidental findings on cross-sectional imaging. Mostly asymptomatic, accessory muscles sometimes mimic mass lesions. They have been implicated as the cause of…
There are many challenges involved in obtaining diagnostic MR images of the foot and ankle. The complex anatomy and morphology, with curved and angular structures localized to the periphery of…
