Rod Link Reducer

3-PLANE DEFORMITY CORRECTION TECHNIQUE

Originally developed at the Texas Scottish Rite Hospital for Children, the Rod Link Reducer technique is designed to aid in the correction of severe spinal curvatures with a novel set of instruments. This technique increases leverage to manipulate the spine in the axial, coronal and sagittal planes.

During the procedure, Manipulating Arms are attached to provisional rods which are placed proximal and distal to the apex of the curve. The Manipulating Arms are used to correct the deformity in three planes. The deformity is manipulated into a corrected position, then the construct is rigidly locked in place while a permanent rod is installed on the contralateral side.

Advantages of the Rod Link Reducer Technique

  • Technique may help improve scoliosis correction and reduce operative time compared to traditional methods1
  • Allows controlled correction of severe sagittal, coronal, and axial deformity
  • Holds and maintains correction during rod placement

REDUCTION TECHNIQUE OVERVIEW

Axial

The first manipulation is axial derotation of the spine and the rib cage for transverse (axial) correction. This is performed by pressing down on the manipulating arms.

Coronal

The second manipulation is compression of the spine on the convexity for coronal correction. This is performed by bringing the manipulating arms together.

Saggital

The third manipulation is to restore thoracic kyphosis for sagittal correction. This is performed by rotating the handles of the manipulating arms simultaneously.
