The olecranon fracture of ulna was fixed with steel plate and taken out with external fixator 6 weeks after operation. Limited movement, stretching 140 degrees, bending.

First of all, all these things you said are normal phenomena in the process of normal recovery, so don't worry.

After 4 weeks of fixation, even normal people can't bend their joints, so your situation is not surprising. Swelling is also the most common phenomenon of fracture.

Secondly, functional exercise is a very painful process. Many patients I have managed are sweating all over or crying in pain, so I can tell you that rehabilitation training is very painful, but for the sake of joint function in the future, you must stick to it!

Your main problem now is limited flexion and extension. You can use hot compress first, and more importantly, you can practice flexion and extension by yourself. This is a positive activity. You can also ask your family for help. This is a passive activity. To put it bluntly, it is to help you mix, but not too violent. I have also seen my patients practice with a brick to let gravity straighten their arms. Of course, this is the time when the fracture has healed.

By raising the affected limb, the swelling can be reduced, and the swelling can also be reduced by taking drugs, which will gradually recover.

Finally, encourage me, the process is very painful, but stick to it and hope you can recover your function as soon as possible!
