Although the etiology remains unknown, surgical identification of nerve torsions and recent advances in diagnostic imaging, particularly high-resolution ultrasound and MRI, have introduced a distinct entity known as hourglass-like constriction (HLC), which may be a manifestation of Parsonage-Turner syndrome.

Exploration showed a severe fibrous thickening of the anterior division was found, revealing an HLC. The unsalvageable nerve portion was resected, and direct suture was performed.
