Isolated Atraumatic Injury of the Supraspinous and Interspinous Ligaments

We reported a rare case of atraumatic injury to the supraspinous and interspinous ligaments in a 33-year-old woman. Without the typical history or imaging findings of trauma to the vertebral bodies, imaging findings associated with injury to the posterior ligament complex may be difficult to distinguish between posterior ligament complex rupture, lumbar strain, or fluid collection. This case highlighted the radiologic modalities and imaging findings that may aid in the diagnosis and treatment of equivocal cases.
