Homans sign

Homans' sign is a medical sign that is often used to test for Deep vein thrombosis (DVT). It was named after John Homans, an American surgeon who described the sign. However, it is no longer recommended for clinical use due to its poor sensitivity and specificity.

Definition

Homans' sign is defined as pain in the calf or popliteal region (the area behind the knee) upon forced dorsiflexion of the foot with the knee fully extended. This is thought to stretch the gastrocnemius and soleus muscles, which may be tender if a clot is present in the deep veins of the calf.

Clinical significance

While Homans' sign can be present in cases of DVT, it is not a reliable sign. Many patients with DVT do not have a positive Homans' sign, and many patients without DVT do have a positive Homans' sign. Therefore, it is not recommended for use in clinical practice.

History

Homans' sign was first described by John Homans in 1944. However, it has been largely replaced by more accurate diagnostic tests for DVT, such as ultrasound and D-dimer testing.
