Cotrel–Dubousset Instrumentation

Cotrel–Dubousset Instrumentation is a type of spinal instrumentation used in orthopedic surgery to correct spinal deformities. It was developed by French surgeons Yves Cotrel and Jean Dubousset in the 1980s.

History[edit | edit source]

The Cotrel–Dubousset Instrumentation was introduced in 1984 as a revolutionary approach to treating severe spinal curvature. Prior to its development, surgeons relied on the Harrington rod, which had limitations in terms of rotational correction and preservation of sagittal balance. The Cotrel–Dubousset system offered a more comprehensive solution, allowing for three-dimensional correction of the spine.

Design[edit | edit source]

The Cotrel–Dubousset Instrumentation consists of metal rods, hooks, and screws that are implanted into the spine. The rods are contoured to match the desired spinal alignment, and the hooks and screws are used to anchor the rods to the vertebrae. The system is designed to provide both anterior and posterior support to the spine, allowing for correction in all three planes: coronal, sagittal, and axial.

Procedure[edit | edit source]

During the spinal fusion surgery, the surgeon makes an incision in the patient's back to expose the spine. The hooks and screws are then inserted into the vertebrae, and the rods are attached. Once the rods are in place, the surgeon adjusts them to correct the spinal deformity. The procedure is typically followed by a period of physical therapy to help the patient regain strength and mobility.

Complications[edit | edit source]

As with any surgical procedure, there are potential complications associated with the Cotrel–Dubousset Instrumentation. These can include infection, nerve damage, and failure of the instrumentation. However, the system has been widely used for over three decades and has a proven track record of safety and efficacy.
