Fusion of cervical vertebrae from a basal archosauromorph from the Middle Triassic Denwa Formation, Satpura Gondwana Basin, India.

This report describes two adjacent, longitudinally-fused anterior cervical vertebrae from a basal archosauromorph. The specimen was collected from the Denwa Formation, Satpura Gondwana Basin, India. The differential diagnosis of the fusion includes genetic or environmentally-mediated congenital malformations, nonspecific spondyloarthopathy, and various infectious agents. These observations represent the first published recognition of archosauromorph vertebral pathology from specimens that were discovered in India. The observations affirm that basal archosauromorphs suffered from disorders that have been observed in later dinosaurs and modern-day vertebrates. Considering the process of orderly differential diagnosis is an important aspect of understanding lesions of ancient bones.

History of spine surgery for tuberculous spondylodiscitis.

For those stricken with tuberculosis, a disease that was present in ancient times, treatment was originally limited to conservative treatment including high altitude, fresh air, rest, and immobilization, manual reduction devices, and surgical procedures. Mortality and morbidity were high until the advent of antitubercular chemotherapy in the 1940s. Today multidrug regimen enable good disease clearance and also make direct surgical debridement without complications possible. Antitubercular drugs have reduced mortality by 72.5%. Surgical intervention is reserved for selected situations.
