title: Posterior instrumentation of the spine. An experimental comparison of various possible techniques.
abstract: Fourteen variations of posterior instrumentation were tested experimentally, using models based on polyester imitation vertebrae, to determine the most effective method for stabilization of a section of the spine following fracture and, in particular, pathologic fracture. The most rigid construction was a well-fitting steel rectangle fastened to the vertebrae with laminar wires. The addition of bone cement significantly improved rigidity.
