This 1938 monograph by Prof. P. Del Torto belongs to early twentieth-century orthopedic pathology and surgery literature. The work likely examines congenital pseudarthrosis of the tibia, addressing etiological hypotheses, anatomical alterations, clinical presentation, and therapeutic strategies available at the time. Structured as a focused clinical study, it probably integrates case documentation with surgical considerations and long-term prognosis. Its scholarly importance lies in contributing to the understanding of complex congenital bone disorders during a formative stage of modern orthopedic research.
