U-implants of Ukrainian production at lumbar spine stenosis (making and clinical application)
Keywords:spinal stenosis, interspinous fixation, U-implant, neurogenic claudication
The purpose. To evaluate the possibility of U-implants of Ukrainian production application at treatment of lumbar spine stenosis.
Material and methods. Numerous studies (chemical, microscopic, phase analysis) of alloy and strength characteristics of Coflex implant were conducted that gave a possibility to create and successfully conduct clinical trials of new Ukrainian U-implant, characterized from their foreign counterparts both in composition and form, and also to obtain a certificate of state registration.
Results. Chemical analysis showed that the product, according to the classification adopted in the world, corresponds to alloy Grade 5, or Ti-6Al-4V, the analogue of the alloy BT6. This alloy application provides better strength characteristics of the product while maintaining it’s plasticity. Application of the Ukrainian implant in clinical practice in 11 cases allowed to reach full recourse of clinical symptoms in the early postoperative period.
Conclusions. Application of a new Ukrainian U-implant after interspinous fixation and preliminary decompression is an effective method for treatment at lumbar spine stenosis.
U-implant of Ukrainian production has a number of positive technical features that improve it’s characteristics.
