What is the outlook for elbow hyperextension?
You should see your doctor right away if you experience symptoms of elbow hyperextension. They can help diagnose the extent of your injury. They can also suggest the best treatment options to help your elbow heal correctly.
In the short term, you should expect to keep your elbow immobilized for at least a few days. If your elbow is severely injured and you require surgery, you will need to keep it immobilized for longer. In most cases, it should heal within a month. You may need physical therapy to help regain your full strength and range of motion. If your elbow doesn’t heal properly or you it repeatedly, you might develop chronic elbow instability. Over time, this can raise your risk of arthritis.
I am not sure if the month comment is for the post surgery scenario or just the run of the mill hyperextension.
Most websites are just saying anti-inflammatory meds, rest, ice and brace, so he may be good to go next week.
