Vittorio Putti has been recognized as one of the founders of orthopedic science. He wrote a number of original papers on different topics from his vast experience of orthopedics. In a paper on bone grafting dated 1912, Putti demonstrated his modern way of thinking by his ability to study past experiences critically and by his willingness to compare his own experiences with those of other orthopedic surgeons.

Histological analysis of bone/heteroplastic implant interfaces in dog tibia.

Ann Anat

February 2004

Department of Anatomy, Methodist University of São Paulo, Rua do Sacramento, 230, São Bernardo do Campo, 09640-000, SP-Brazil.

This work presents histological analysis of interfaces between bone and heteroplastic implants in dog tibias. The study was performed in four tibias (of four mongrel dogs) into which cylindrical implants were inserted. One ceramic (titania) implant and three grit-blasted titanium implants (with sandblasted and acid-corroded surfaces) were chosen for histological analysis of the implant surface/bone tissue interface.

In the Rheumatological Institute in Prague the authors made a retrospective investigation in patients with ankylosing spondylitis affecting the hip joints where one or two endoprostheses of the hip joints were made. In all these patients they evaluated the subjective complaints of the operated extremity, they made a clinical examination of the extent of mobility and evaluated X-ray pictures. The group of 20 patients was examined in this retrospective investigation approximately five years after operation.

Cosmetic aspects and protection of the brain from mechanical injuries are the most common indications for the repair of traumatic and operative cranial defects. We suggest two additional indications: Cranioplasty is not only important in the treatment of space-occupying fluid cysts, but also in preventing or overcoming hemisphere collapse with its resultant displacement of the midline structures. This complication was almost exclusively found in patients subjected to extensive lateral craniotomies and also led to psycho-organic syndromes with disturbances of mood and drive.

The healing of standardized bony defects in the region of the mandible following implantation of various heterologous bony components was controlled in animal experiments via polychromatic sequential labeling. The implant of gelatin foam did not accelerate healing. The combination of gelatin and solcoseryl led to accelerated mineralization in the marginal area.
