Proximal Junctional Kyphosis Despite Best Efforts in Planning and Execution
Concepts in spinal deformity surgery as well as the instrumentation used to surgically treat spinal deformities has constantly been evolving in the last few decades. The biomechanics of the growing, grown and degenerated spine, and the biomechanical effects of the implants used are not yet fully understood. After instrumented fusion, the interchange between the instrumented and non-instrumented spinal segments are referred to as junctional area.
