Lumbar interbody fusion cage LF-III

transforaminalPEEK

The Kidney-Shaped Lumbar Interbody Fusion Cage is manufactured from PEEK (polyetheretherketone) with integrated tantalum radiopaque markers for intraoperative positioning and postoperative imaging. Its kidney-shaped anatomical profile facilitates positioning and provides a close fit between the vertebral bodies during lumbar interbody fusion. The cage uses a distraction-compression stabilization principle to provide immediate segmental support, resist rotational and shear forces, and facilitate axial load transfer for intervertebral fusion. -Features Anatomical Kidney-Shaped Design • Kidney-shaped profile improves positioning and anatomical conformity. • Wedge-shaped endplates help match vertebral anatomy and maintain sagittal alignment. Anti-Migration Design • Pyramidal serrations on the upper and lower surfaces enhance fixation and help prevent cage migration. Large Graft Window • The large central graft window accommodates autograft or synthetic bone substitutes to support fusion. Radiopaque Markers • Tantalum markers facilitate accurate intraoperative positioning and postoperative imaging. PEEK Material • PEEK provides biocompatibility, radiolucency, and bone-like elastic modulus, helping reduce stress shielding and support osseointegration. Advantage • Bullet-tip leading edge facilitates smooth insertion. • Kidney-shaped curvature improves in-body positioning and anatomical fit. • Wedge-shaped surfaces enhance endplate contact and stability. • Pyramidal teeth help reduce the risk of postoperative migration. • Large graft window provides ample space for bone graft material. • Multiple sizes accommodate different patient anatomies.
