The presentation will consider low energy and repetitive injuries to the Pelvis and proximal femur; Knee; Tibia and Fibula; Ankle and finally forefoot. Bony pathologies discussed will include stress, insufficiency and avulsion injuries. Muscle injuries will be demonstrated using US and MRI, and include acute and chronic tears, contusion and myositis ossificans. Discussion of ligament injuries will emphasise the relative roles of US, MRI, and MR arthrography, and associated disorders in adjacent tendons, the sinus tarsi and subtalar articulation.
