A composite thermoplastic elastomeric lumbar disc spacer = : Ein thermoplastischer elastomerer Verbundwerkstoff als Bandscheibenersatz für die Lendenwirbelsäule

The spinal disc may be displaced or damaged due to trauma or a disease process. Although fusion is an excellent method of eliminating symptoms, it results in total loss of motion of the fused vertebral joint. Obviously, a more desirable situation would involve replacing the damaged disc (or part the... Full description

520 |a The spinal disc may be displaced or damaged due to trauma or a disease process. Although fusion is an excellent method of eliminating symptoms, it results in total loss of motion of the fused vertebral joint. Obviously, a more desirable situation would involve replacing the damaged disc (or part thereof) with a suitable mechanical equivalent so as to allow near normal joint motion. Unfortunately, the complex mechanical properties of the lumbar disc can not be duplicated with homogeneous synthetic materials (polymers). To overcome this fundamental problem, a rational design utilizing biocompatible thermoplastic elastomers of various durometers (stiffness) was developed. Biocompatible polysiloxane modified styreneethylene/butylene (SEBS) block copolymers of various durometers were used in a unique two-step compression molding process. All discs were tested in compression and compression/torsion. A range of compressive and torsional properties can be achieved using the design concept, materials and fabrication techniques described.
