Spinal instrumentation is a method of straightening and stabilizing the spine after spinal fusion, by surgically attaching hooks, rods, and wire to the spine in a way that redistributes the stresses on the bones and keeps them in proper alignment.
.performed by a neuro and/or orthopedic surgical team. The surgeon strips the muscles away from the area to be fused. The surface of the bone is peeled away. After the fusion site is prepared, the rods, hooks, and wires are inserted.
Several common types of spinal instrumentation are. Harrington Rod.Luque rods.Drummond instrumentation, also called Harri-Drummond instrumentation.Cotrel-Dubousset instrumentation.Zeilke instrumentation.The Kaneda device.Wisconsin instrumentation
Spinal instrumentation is used to treat instability and deformity of the spine. Instability occurs when the spine no longer maintains its normal shape during movement.
Spinal instrumentation carries a significant risk of nerve damage and paralysis.
Since the hooks and rods of spinal instrumentation are anchored in the bones of the back, spinal instrumentation should not be performed on people with serious osteoporosis. To overcome this limitation, techniques are being explored.
Spinal instrumentation is used to treat instability and deformity of the spine. Such instability results in nerve damage, spinal deformities, and disabling pain. Spinal deformities may be caused by: birth defects.fractures.tumors.scoliosis.
Spinal instrumentation carries a significant risk of nerve damage and paralysis. there is a risk of infection or an inflammatory reaction due to the presence of the foreign material in the body. the instrumentation may move or break.
Not all patients require instrumentation with their spinal fusion. For some patients, a rigid external brace can provide the required rigidity to allow the bones to fuse.
Many young people with scoliosis heal with significantly improved alignment of the spine. Results of spinal instrumentation done for other conditions vary widely.
types of spinal instrumentation. Zeilke instrumentation is similar to Cotrel-Dubousset instrumentation, but is used to treat double curvature of the spine. It requires wearing a brace for many months after surgery.
types of spinal instrumentation. Drummond instrumentation, also called Harri-Drummond instrumentation, uses a Harrington rod on the concave side of the spine and a Luque rod on the convex side.
types of spinal instrumentation. Cotrel-Dubousset instrumentation uses hooks and rods in a cross-linked pattern to realign the spine and redistribute the biomechanical stress.

During the fusion operation, a set of rods, wires, or screws will be attached to the spine. This instrumentation allows the spine to be held in place while the bones fuse.
types of spinal instrumentation. The Kaneda device is used to treat fractured thoracic or lumbar vertebrae when it is suspected that bone fragments are present in the spinal canal.
