A 20-year-old man presents with severe ankle pain and deformity after a fall from a ladder. He is unable to bear weight. What is the likely diagnosis and what should be the next step?
The patient's symptoms suggest a potential ankle fracture, likely a bimalleolar equivalent or trimalleolar fracture, given the mechanism of injury and his inability to bear weight. The next step should be to immobilize the ankle, administer analgesics as needed, and obtain ankle X-rays to confirm the diagnosis and determine the extent of the fracture. This will likely require orthopedic evaluation for potential surgical intervention.
