Injuries that result in fractures (broken bones), ruptured ligaments and dislocations
Osteoarthritis - wear-and-tear arthritis. It can also cause deformity.
Tendinitis - irritation of the tendons
Dupuytren’s contracture - a hereditary thickening of the tough tissue that lies just below the skin of your palm. It causes the fingers to stiffen and bend.
Trigger finger - an irritation of the sheath that surrounds the flexor tendons. It can cause the tendon to catch and release like a trigger.
