Broken Ankle TREATMENT and Surgery Doctors usually place a splint on the injured ankle for some days to 14 days until the swelling decreases around the joint . The kind of fracture and the balance of the fractured joint will determine the type of splint which will be utilized, or whether surgery is necessary.If the ankle bones aren’t aligned and/or dislocation is suspected properly, the physician might realign them before placing the splint. If the bones cannot be realigned in the emergency department properly, the patient may require an operation. Surgery could be needed if any bone has broken through your skin also. If the bone breaks through the skin, the fracture is called a compound fracture.
