Foot and ankle
Review the relevant anatomy and imaging question before deciding what the finding may mean for rehabilitation.
Key imaging concepts
- Different projections assess the malleoli, talar dome, mortise, midfoot and forefoot. Alignment of the mortise and tarsometatarsal joints may be key.
- Distinguish sprain from potential fracture and be aware of common missed injuries such as navicular, talar or Lisfranc patterns.
- Ottawa ankle/foot rules guide radiograph decisions only in appropriate acute trauma presentations and depend on reliable examination.
PT clinical connection
Concerning midfoot plantar bruising, disproportionate pain or inability to bear weight needs medical assessment even if the first X-ray is normal.
High-yield distinction
Mortise and midfoot: Check tibiotalar alignment and distal syndesmosis; clinical suspicion for Lisfranc injury warrants appropriate urgent assessment.
