Introduction
The Aaro Anterior Spine System is applied on the convex side of the deformity.
It uses a simplified technique which permits an optimal correction of the spine with low profile instrumentation.
The implant consists of a rod with a rectangular profile connected to a plate. Cancellous screws are used to fixate the plate to the vertebral body. A setscrew fixates the rod.
Correction of the rotation is achieved by the rectangular profile of the rod.
All components are made of titanium alloy (TI6AL4V).
Gentle technique
The system is designed to facilitate complicated corrections of thoracic, thoraco/lumbar or lumbar scoliosis.
Some patients with neuro muscullary scoliosis develop osteoporosis. The Aaro Anterior Spine System is well suited for these patients:
- Application of the components and correction is performed with a gentle technique that places minimal stress on the spine.
- The correction technique is performed with compression only (no distraction), resulting in minimal stress on the spinal cord.
Simplified correction technique
The rectangular profile and the segmental construction of the rod makes it flexible in the frontal plane but rigid in the sagital plane. Different connection plates are used in the sagital plane to create kyphosis, lordosis or a straight spine. The advantages of this design are:
- A simple and easy application of the connection plates.
- A simple "step by step" compression technique that is performed until correction is achieved.
- A low profile system with a maximum height of 9 mm. Using the system on the Thoracic spine the implants can normaly be covered with the pleura.
The Aaro Anterior Spine System G4 is designed to be used for small patients or in the thoracic spine. The size of the small components are about 40% less than components included in the G3 system.
