Final answer:
Lateral process fractures of the talus usually require surgical repair with open reduction and internal fixation when displaced more than a certain threshold, commonly 0.2 to 0.5 cm, but the exact value may vary depending on various factors.
Step-by-step explanation:
Lateral Process Fractures of the Talus
Lateral process fractures of the talus are typically repaired with open reduction and internal fixation when the fractures are displaced by a certain threshold. While specifics are not provided in the reference material, it is commonly accepted in orthopedic practice that when fractures are displaced more than 0.2 to 0.5 cm, surgical intervention is suggested to ensure proper alignment and healing. Open reduction and internal fixation may consist of the use of metal plates and screws to stabilize the fracture, similar to the surgical treatment described for unstable fractures of the radius.
In the context of fractures and their treatment, it is important to realize that the actual displacement requiring surgery can depend on multiple factors, including the specific bone involved, the type of fracture, the patient's age, activity level, and overall health. Therefore, the exact numerical value for when surgery is indicated for lateral process fractures of the talus should be confirmed based on current medical guidelines and practice.
