Instep sprain swollen is fracture

If there is a definite history of injury accompanied by swelling of the instep, two possibilities need to be considered: the first is the common metatarsal fracture, especially the fifth metatarsal fracture; the second is due to ankle sprain, especially the lateral ankle sprain, resulting in lateral collateral ligament damage, will also show swelling of the instep lateral; their common manifestations are swelling, bruising, tenderness, and walking difficulties of the patient's foot. The most reliable way to rule out fractures is through reliable X-ray examinations, even CT and MRI. MRI can also see whether there are tears in ligament tissue and local hematoma.
