Robinson-Fournier Symptom

Robinson Fournier symptom is a pathognomonic sign of damage to the phrenic nerve. It is expressed in atony or hypotension of the diaphragm, in the absence of inspiration when raising the limbs above the horizontal plane (the “scissors” symptom). Clinically characterized by retraction of the abdominal wall with divergence of the rectus abdominis muscles in the act of exhalation, systolic trembling of the diaphragm. Surgical and conservative methods are used to treat damage to the phrenic nerves. Lack of effect is observed in 25–35% of patients with duplex forms of traumatic and compression injuries of long diaphragmatic fibers on
