A talus fracture is typically caused by a high-energy trauma, such as a fall from a height or a motor vehicle accident. It can also be caused by a low-energy trauma, such as an ankle sprain or a twisted ankle.
Talus fractures can be diagnosed through physical examination and imaging tests, such as X-rays or CT scans. An X-ray can usually detect a fracture, while an MRI can provide more detailed information about the fracture.
Other conditions that may be considered in the differential diagnosis of a talus fracture include ankle sprains, ankle instability, osteoarthritis, and gout.
Treatment for a talus fracture will depend on the type and severity of the fracture. Treatment may include immobilization with a cast or splint, physical therapy to restore strength and range of motion, and, in some cases, surgery to repair the fracture.
The prognosis for talus fractures is generally good, though it will depend on the type and severity of the fracture. The majority of talus fractures heal without complications and without the need for surgery.
