Spontaneous Fusion of S2/S3 Spondyloptosis in an Adult

Background Spondyloptosis is grade V on the Meyerding classification. Traumatic spondyloptosis can occur throughout the spinal column, particularly at junctional levels, and finding an ideal surgical strategy to address it remains a challenge for spinal surgeons. The sacrum is considered a united bone in adults, and sacral intersegmental spondyloptosis is extremely rare. Case Report Herein, we present an unusual case of S2/S3 spondyloptosis in a 27-year-old female patient with spontaneous solid fusion. Conclusions This case demonstrates that similar distal sacral pathologies may be managed conservatively when there is no associated neurologic deficit, and the osteodiskoligamentous integrity of the lumbosacropelvic unit remains intact. Our report plus the very few published papers in the literature illustrate the natural history of uncomplicated traumatic spondyloptosis and support the role of in situ fusion and instrumentation as a reliable alternative to circumferential fusion in patients who cannot tolerate staged or prolonged operations.
