Palmar digital arteries

Palmar digital arteries are a group of arteries that supply blood to the fingers of the hand. These arteries are crucial for the vascularization of the digits, ensuring that the tissues receive adequate oxygen and nutrients.

Anatomy

The palmar digital arteries are branches of the superficial palmar arch and the deep palmar arch. They are divided into two main types:

• Common palmar digital arteries: These arteries arise from the superficial palmar arch and run along the metacarpal bones. Each common palmar digital artery bifurcates into two proper palmar digital arteries.
• Proper palmar digital arteries: These arteries supply the sides of the fingers. They run along the sides of the phalanges and provide blood to the skin, subcutaneous tissues, and bones of the fingers.

Function

The primary function of the palmar digital arteries is to supply oxygenated blood to the fingers. This is essential for maintaining the health and function of the tissues in the digits, including the skin, muscles, and bones.

Clinical Significance

Damage or obstruction to the palmar digital arteries can lead to conditions such as ischemia or necrosis of the fingers. This can occur due to trauma, Raynaud's disease, or other vascular disorders. Proper diagnosis and treatment are essential to prevent permanent damage to the digits.
