Knuckle Pads (Symptoms,Causes and Treatment)

Knuckle pads, also known as knuckle calluses or Garrod’s pads, are benign and painless skin growths that typically occur on the dorsal (back) surface of the finger joints, particularly over the proximal interphalangeal (PIP) joints and metacarpophalangeal (MCP) joints. They may also appear on the toes.

Brief information about Knuckle Pads disease:

*Appearance: Knuckle pads are small, raised, and thickened areas of skin. They may be flesh-colored, reddish, or darker in appearance.

*Texture: The skin over knuckle pads is often smooth and firm, similar to calluses.

*Size: Knuckle pads can range in size from a few millimeters to a few centimeters in diameter.

*Causes: The exact cause of knuckle pads is not fully understood. They are believed to be caused by repeated friction or pressure on the knuckles, leading to the thickening of the skin.

*Associated Conditions: Knuckle pads can be associated with certain conditions, such as Dupuytren’s contracture and Ledderhose disease, which involve the formation of similar nodules in other parts of the body, such as the palms and feet.

*Symptoms: Knuckle pads are usually asymptomatic and do not cause pain or functional impairment. However, in some cases, they may be cosmetically bothersome or restrict joint movement if they become excessively thick.

*Treatment: In most cases, knuckle pads do not require treatment, as they are harmless. If they cause functional issues or cosmetic concerns, they can be treated with conservative measures such as topical corticosteroids or silicone gel sheets to soften and flatten the skin. Surgical removal is possible in some cases, but recurrence is possible.
