Trigger Finger

Stenosing tenosynovitis is commonly known as “trigger finger” or “trigger thumb.” The tendons that bend the fingers glide easily with the help of pulleys. These pulleys hold the tendons close to the bone. This is similar to how a line is held on a fishing rod (Figure 1). Trigger finger occurs when the pulley becomes…

A mallet finger is a deformity of the finger caused when the tendon that straightens your finger (the extensor tendon) is damaged. When a ball or other object strikes the tip of the finger or thumb and forcibly bends it, the force tears the tendon that straightens the finger (see Figure 1a and 1b). The force…

Dupuytren Contracture

Dupuytren’s contracture is an abnormal thickening of the tissue just beneath the skin. This thickening occurs in the palm and can extend into the fingers. Firm pits, bumps and cords (thick lines) can develop and cause the fingers to bend into the palm (Figures 1 and 2). This condition may also be known as Dupuytren’s Disease. Occasionally, the disease will…

Carpal Tunnel Syndrome

Carpal tunnel syndrome is essentially a pinched nerve in the wrist. There is a space in the wrist called the carpal tunnel where the median nerve and nine tendons pass from the forearm into the hand. Carpal tunnel syndrome happens when pressure builds up from swelling in this tunnel and puts pressure on the nerve. Causes Pressure on…
