Flexor tetanus, a medical condition affecting the muscles, can also be referred to by various synonyms. One such synonym is Tonospasm, which characterizes the muscle stiffness and sustained contraction typically seen in patients with this condition. Another synonym is Lockjaw, which highlights the clenched jaw and restricted movement of the jaw muscles, often associated with flexor tetanus. Moreover, Opisthotonos is another term used to describe the intense muscle stiffness, particularly in the neck and back, resulting in the patient assuming an arched position. These synonyms allow healthcare professionals and patients to better understand and communicate the symptoms and characteristics of flexor tetanus, facilitating accurate diagnosis and appropriate treatment.
