Question: The knuckle on my middle finger on both hands, where the finger joins the hand, goes out of joint under normal use. There is no pain when this happens, but sometimes the joint becomes sore and it's very aggravating. What causes this and can anything be done to prevent it?
Dr. Hibberd's Answer:
You have an inherited hyperlaxity of ligamantous structures.
There is no known preventive therapy that is effective for preventing deterioration except to avoid repeated overstressing of these joints and avoid "popping" these joints.
If dislocation recurs, you may be able to find some therapeutic options through consultation with a hand surgery specalist (often orthopedics or plastic surgeons).
