Biologically and mechanically compatible titanium nickelide implants in the treatment of injuries of the thoracic and lumbar spine

Abstract

Based on the concept of biomechanic and biochemic compatibility of nikelide Ti implants with body tissues the application of devices with form memory effect as well as superelasticity for the treatment of uncomplicated compressive fractures of thoracic and lumbar spine was substantiated. Fixators played the role of so called endoprostheses for the injured posterior ligamentous apparatus resulted from superelasticity. In cases without severe disorders of spine mobility in postoperative period those fixators allowed early activization and rehabilitation of patients. On the basis of clinical outcomes of 32 patients with vertebral body fractures efficacy of posterior fixation by nikelide Ti brackets has been proven.
