What is one function of Cotrel-Dubousset and Isola instrumentation?

The function of Cotrel-Dubousset and Isola instrumentation primarily involves the restoration of normal vertebral column alignment. These systems are designed for internal fixation and stabilization of the spine, particularly in cases such as scoliosis or spinal deformities. By providing rigid support, they help to maintain the alignment of the vertebral bodies, which is crucial for achieving proper spinal function and aesthetics post-surgery.

The instrumentation works by using a combination of rods, hooks, and screws to secure the spine in a corrected position, allowing for a more natural curvature and promoting healing. This alignment is essential not only for structural integrity but also for the prevention of neurological complications that can arise from misalignment.

The other functions mentioned—enhancing muscle repair, reducing inflammation in spinal tissues, and strengthening ligaments—are not direct functions of these instrumentation systems. While improving alignment may indirectly contribute to overall spinal health, the primary goal of Cotrel-Dubousset and Isola systems is to stabilize and correct the alignment of the vertebral column itself.
