Homans sign
Homans' Sign
Homans' Sign (pronounced: HOE-manz sign) is a clinical sign that is often used in the diagnosis of Deep Vein Thrombosis (DVT). It was named after the American physician John Homans, who first described it in 1944.
Etymology
The term "Homans' Sign" is derived from the name of its discoverer, Dr. John Homans. Dr. Homans was a prominent American surgeon and a pioneer in the field of vascular surgery.
Definition
Homans' Sign is a physical examination finding that is suggestive of a Deep Vein Thrombosis (DVT). It is elicited by dorsiflexion of the patient's foot with the knee bent, which may cause pain in the calf muscle. However, it is important to note that the presence or absence of Homans' Sign is not definitive for DVT and further diagnostic testing is usually required.
