This second annual volume of a mid-twentieth-century medical journal is dedicated to orthopedics and musculoskeletal surgery, continuing the scientific program established in its inaugural year. Anno II (1951) presents clinical research articles, operative case studies, and theoretical analyses concerning trauma, congenital deformities, and degenerative joint conditions. The publication reflects the consolidation of orthopedic specialization in postwar Italy, integrating anatomical research, radiological evaluation, and surgical methodology. Intended for orthopedic surgeons and medical academics, it documents the expanding institutional framework of orthopedic science.
