Part Description

LP72739-3   Homans sign
In medicine, Homans' sign is a sign of deep vein thrombosis (DVT). A positive sign is present when there is pain in the calf or popliteal region with examiner's abrupt dorsiflexion of the patient's foot at the ankle while the knee is flexed to 90 degrees This sign is frequently elicited in clinical practice because of the ease of use, although it is falling into disfavor because of poor reliability and because it is frequently positive in individuals without DVT. A positive Homans' sign does not positively diagnose DVT (poor positive predictive value), and a negative Homans' sign does not rule out the DVT diagnosis (poor negative predictive value). The use of Homans' sign is now discouraged by some as it may unlodge a thrombus leading to a thromboembolic event.
