Zielke Instrumentation

It uses a flexible rod attached to the convexity or outside of the curve with screws. Correction is achieved by compression of the curve. Other systems which can be used for an anterior procedure include the Dwyer, which is similar to the Zielke, the TSRH and the Isola, as well as others. An anterior fusion may be performed alone or frequently in conjunction with a posterior fusion.

Zeilke instrumentation is similar to Cotrel-Dubousset instrumentation, but is used to treat double curvature of the spine. It requires wearing a brace for many months after surgery.
