Which instrumentation system is used to restore normal vertebral column alignment?

The Cotrel-Dubousset and Isola systems are designed specifically for spinal surgeries where restoring normal vertebral column alignment is essential. These instrumentation systems utilize rods, screws, and hooks that help stabilize the spine during the healing process and are commonly used in cases of scoliosis or other spinal deformities. Their design allows for correction of the vertebral alignment while providing the necessary support to maintain structural integrity post-surgery.

In contrast, while the other systems mentioned may be involved in various surgical or monitoring procedures, they do not focus specifically on the restoration of vertebral alignment in the same manner as the Cotrel-Dubousset and Isola systems. The CMRR and CMRO are terms that relate more to neuromonitoring and anesthesia, while the Du Bois and Reymond system is not recognized in the same context of spinal alignment. TCD, or Transcranial Doppler, is an ultrasound method used for assessing cerebral blood flow rather than for orthopedic alignment. Thus, the specificity and design purpose of the Cotrel-Dubousset and Isola system make them the correct choice for restoring normal vertebral column alignment.
