Grade I sprains and mild strains are usually self-diagnosed. Grade II and III sprains are often seen by a physician, who x rays the area to differentiate between a sprain and a fracture.
grade III
A grade 1 sprain is a mild injury where there is minimal stretching or tearing of ligaments. In contrast, a grade 2 sprain is a moderate injury involving partial tearing of ligaments, leading to more pain, swelling, and sometimes bruising. Grade 2 sprains typically take longer to heal and may require more intensive treatment.
grade III
grade III
The definition of a sprain is the tearing or stretching of ligaments. Sprains are usually classified in severity from grade I through grade III. To answer your question a twisted ankle can result in a grade I through III sprain or no sprain at all depending on the severity of the trauma (twisting).
Grade I or 1st degree sprains take the least time to heal because they caused the least damaged to the ligament or tendon.
Ankle sprains are defined the the location and severity of the overstretch or tear. An ankle sprain can range from grade 1 to 3 based on whether the sprain was mild, or represented a complete tear, or something in-between.
Grade III is the most serious injury. The 3 main ligaments of the lateral ankle are all torn. They heal more slowly than bone because they have very poor blood supply. If a second sprain were to occur before it completely heals, you could end up with a permanently unstable ankle. Therefore it is extremely important that it is completely healed before attempting any quick lateral movements. Depending on your age and ability to heal (how well blood flows to the area is key), I would estimate 6 months of healing and rehab before you are completely out of the "woods."

There are three stages of AC shoulder separation to heal. A grade one separation could heal on it's own in a couple of weeks, while a stage three separation often requires surgical repair and can take months to heal.
Not necessarily, it very much depends on different factors such as: exact type of fracture, whether there is any displacement of the fracture, the age and functional expectations of the patient etc. If you are talking about a displaced medial tibial plateaux fracture (Shatzker grade 4) in a young active person, then YES it would need to be fixed. An undisplaced fracture in an elderly patient with limited mobility probably would not need fixed surgically but treated in a cast brace.
