Patient: Description (onset time, main symptoms, hospital, etc.): I am 25 years old, male, in my 12 years ago due to an accident I fractured my left arm, after surgery and then because of the lack of strengthening exercise, the arm can only be straightened in a state of tension, and there is no added force to extend backwards also not straight, I would like to ask, my condition can be treated well? I am now a bachelor’s degree graduate and have been ashamed of this condition for 12 years without wearing short sleeves, so far I have not been able to find a job, if you can help me to treat it, I will be very grateful to you, how can I straighten it? Answer: Your situation is worthy of sympathy, but first you have to establish confidence in life, you are an undergraduate student, your own ability to decide you can contribute to society, can not give up the pursuit of life because of some local body function is not complete, our beloved Premier Zhou because of the elbow injury, the elbow joint can not be straight, but he was respected by the people of the world with his personal charisma. From your description, you are triceps (the muscle that controls elbow joint extension) weakness, can straighten with the help of external force, indicating that your elbow joint mobility is normal, so what you can do is to exercise the triceps against resistance, a puller is a better tool. If your triceps strength gradually increased still can not straighten, you can go to the hospital to ask a specialist to check whether you can do the tightening of the triceps tendon, this surgical method is not in the books, just from the theoretical speaking can do this surgery.
