Thumb CMC/Basal Joint Arthritis
Arthritis is an inflammatory condition of joints. There are several types of arthritis; the most common type is osteoarthritis or wear-and-tear arthritis that affects the joint at the base of the thumb. Thumb arthritis is more common in women than men, and usually occurs after the age of 40 years. Patients who have arthritis of the fingers may have swelling, pain, stiffness, and malformation all of which interfere with use of the hand.

The ability to bend the fingers is governed by supportive tendons that connect muscles to the bones of the fingers. The tendons run along the length of the bone and are kept in place at intervals by tunnels of ligaments called pulleys. When the fingers bend or are straightened, a slippery coating called tenosynovium helps the tendons smoothly glide through the ligaments with reduced friction.

Fingers are fine structures of the human body that assist in daily activities through coordinated movements. The five fingers of each hand are comprised of 14 bones called phalanges. Injury to these bones can have a huge impact on your quality of life. A fracture of the finger may disrupt the alignment of the whole hand causing pain and stiffness.

Finger dislocation is a condition in which the bone of your finger has moved away from its normal position. Dislocation can be caused from jamming or overextending the finger during sports activities, or during a fall with an outstretched hand.

Finger and Thumb Sprain
Injuries that involve tearing or stretching of the ligaments of your thumb or fingers are termed as sprains. Sprains in the fingers and thumb are most often caused from a fall when you extend your arms to reduce the impact of the fall, or from over-use or repetitive activity of the thumb such as with texting.

Flexor Tendon Lacerations
Tendons are bands of fibrous tissue that connect muscles to bone. When a muscle contracts, the tendon pulls the bone, causing it to move. The movement of the fingers is controlled by muscles in the forearm. Tendons attached to these muscles run through the wrist and help the fingers to move.

Mallet finger is a condition where the end of the finger is bent and does not straighten. It occurs when the extensor tendon on the back of the finger is damaged. The finger joint is a hinge-joint that allows bending and straightening of the fingers. Each finger is composed of 3 phalanges bones, joined by 2 interphalangeal joints (IP joints).

Finger Tip Injuries
Injuries to the fingertip can involve crushing, tearing, or amputation (cutting-off) of the tips of the fingers, which can occur at home, work or during play. Fingertip injuries can occur during every-day activities while using a knife, a lawnmower or snow blower, or when we jam our hands/fingers in the door.

Dupuytren's Contracture is a hand condition where thickening of the underlying fibrous tissues of the palm cause the fingers to bend inward. Patients with this condition are unable to fully straighten the affected fingers.

A laceration is a tear or ragged opening in the skin usually caused by an injury or trauma. A laceration may be either a partial laceration or a complete laceration. Tendons connect muscles to bones and allow coordinated movement of the joints. A deep cut or laceration on the palm side of the hand can damage the flexor tendons, which control movement in your hand.
