Finger Locking: Causes, Symptoms & Treatment Options

* Tendon injuries: These can occur due to overuse, trauma, or inflammation. When a tendon is injured, it can cause the finger to lock up because the tendon is no longer able to glide smoothly through its sheath.

* Ligament injuries: Ligaments are tough bands of tissue that connect bones together. When a ligament is injured, it can cause the finger to lock up because the ligament is no longer able to hold the bones in place.

* Fractures: A fracture is a broken bone. When a bone in the finger is fractured, it can cause the finger to lock up because the broken bone is no longer able to move properly.

* Dislocations: A dislocation is when a bone is moved out of its normal position. When a bone in the finger is dislocated, it can cause the finger to lock up because the bone is no longer able to move properly.

* Arthritis: Arthritis is a condition that causes inflammation of the joints. When arthritis affects the finger joints, it can cause the finger to lock up because the inflammation can cause the joints to become stiff and painful.
