Spinal instrumentation refers to the use of various devices, such as screws, rods, plates, and cages, to stabilize and support the spine during spinal fusion surgery or to correct spinal deformities. These instruments are implanted along the spine to provide stability while fusion occurs or to realign and maintain proper spinal alignment.

In spinal fusion surgery, instrumentation is used to immobilize the spine and promote the fusion of adjacent vertebrae, which can help alleviate pain and stabilize the spine in cases of instability or degenerative conditions.

In cases of spinal deformities such as scoliosis or kyphosis, spinal instrumentation is often combined with spinal fusion to correct the curvature of the spine and maintain proper alignment.

Spinal instrumentation can be made of various materials, including titanium, stainless steel, or non-metallic materials, and may be customized to fit the individual patient’s anatomy and specific surgical needs.
