Individual Replacement of Bones and Joints the Foot in the Treatment of Degenerative Dystrophic Diseases

The aim of the investigation is to increase the efficiency of treatment of osteoarthrosis deformans of foot and ankle joints by developing and applying new hi-tech methods of treatment – individual replacement of the foot bones and joints.

Materiales and Methods. 39 patients with the specified pathology were surveyed. Standard total ankle replacement was performed in two of them (STAR, W. Link), 16 patients underwent the first MTP joint replacement with Total toe system. In five cases with the 1st MTPJ arthrosis there was observed total, subtotal and polylocal aseptic necrosis of the head of the first metatarsal bone. 10 patients had a similar picture of damage of the talus due to trauma. For these patients individual artificial implants of the talus and endoprostheses of the first MTPJ were developed. Modern techniques (CT, MRT) were used to early radiodiagnosis of posttraumatic talus damage.

Results and Discussion. There were developed new methods of surgical treatment of such consequences of trauma of the talus as total, subtotal and polylocal aseptic necrosis — individual total replacement of the talus by original patented technique and replacement of the first MTP joint in cases of severe aseptic necrosis of the 1st metatarsal bone’s head with the implant with the long stem (when standard joint replacement is noneffective). Pre-production models of implants and tools were made, and technical tests of designs were carried out.
