- Finger fractures/breaks (both simple and complex)
- Tendon injuries that prevent the tip joint of the finger remaining straight, known as a mallet finger injury.
- Dislocated fingers (usually involving the ligaments of the joints)
- Thumb or finger sprains or strains
The thumb’s role equates to about 40% of our overall hand function. Some say that the little finger has the next highest functional value in the hand.
The middle joint of the finger, the proximal interphalangeal joint (PIP Joint), makes up for 85% of the bend in the finger in each finger.
The loss of movement in one finger, or one finger joint, will often affect the motion of the adjacent digits and consequently the whole hand. Motion and function can be affected.
Use of the tip joint of the finger, the distal interphalangeal joint (DIP joint), contributes approximately 20% of overall grip strength.
Each finger joint is important to using our hands and can greatly impact everyday activities if injured.
It is important to seek further professional opinion if you have an injury to your thumb, fingers or hand to maximise recovery potential following injury or disease processes, such as arthritis.
