This orthopaedic monograph, Le scoliosi by Ugo Del Torto, in its second edition (1975), presents a structured clinical and therapeutic analysis of spinal deformities, with emphasis on the classification, diagnosis, and treatment of scoliosis. The work combines anatomical, biomechanical, and radiological perspectives, and reflects Italian orthopaedic practice in the pre-molecular, pre-digital imaging era. It includes case studies and discusses both conservative and surgical approaches, offering a reference for specialists in orthopaedics, rehabilitation, and postural medicine. Its systematic structure made it a teaching and clinical tool in Italy’s 1970s medical environment.
