I have 2 fingers on right hand 4th & 5th won't bend after fracture healed. is there a way to get them to bend again, an what is cause?

Probably/Unsure: After a fracture and the immobilization required to let the fx heal, the joints can freeze up. You should work with your doctor, the orthopedist or whomever and see a physical therapist who specializes in pt of the hand. You may gain some or all of your motion. If not, you may have to see a hand surgeon to see if there is more treatment to restore your motion. Don't delay.

Depends: Hard to answer without more detailed info i.E when was the fracture, what type, into the joint?, etc... But if it healed right and in good position, therapy should help. You should see someone to have it evaluated. Best of luck.

Finger motion: It is very common for fingers to become stiff after immobilization from surgery and or injury. The fingers have a sophisticated system of pulleys and cables that allow for the complex motion to smoothly occur between the joints. Scar tissue after healing limits the gliding/sliding of pulley and cables. Therefore, aggressive therapy aimed at restoring rom is needed. Follow your doctors guidelines.
