French to English Medical Medical (general)

This term appears in the physical examination report on a patient who suffered a right shoulder injury. The sentence in question reads as follows: “La palpation de la région sternoclaviculaire et acromio-claviculaire du côté gauche est indolore et ne démontre aucune chaleur, aucun empattement.” I assume that “empattement” should be “empâtement”. If so, does “empâtement” here refer to thickening (such as the thickening of tendons)?
