The pathogenesis of spinal posterior ring apophysis separation (PRAS) remains controversial, and spontaneous regression of PRAS has not been established previously. This is a case report about a 33-year-old man with a PRAS of the posterior superior end plate of S1 who presented with spontaneous low back pain followed by right leg pain. The patient was managed conservatively. A control lumbar spinal computed tomography scan performed 3 years later revealed complete spontaneous regression of the detached bony fragment.
Case Details
Disease Location
S1 vertebrae
Personal Characteristics
33-year-old military man
Clinical Characteristics
Presented with a 3-month history of spontaneous low back pain followed by right leg pain. CT scan revealed a defect in the superior end plate of s1 with avulsion of underlying posterior bony fragment and a combined right paramedian l5-s1 disk herniation
Remission Characteristics
3 years later, a new CT scan was performed showing a spontaneous regression of the posterior bony fragment
Treatment & Mechanisms
Clinical Treatment
Nonsteroidal antiinflammatory drugs
