K2M releases Capri Small 3D Static corpectomy cage system


K2M’s Capri Small 3D Static corpectomy cage system has received 510(k) clearance from the US Food & Drug Administration (FDA). Capri Small 3D Static is a 3D-printed corpectomy cage, and the company’s third product family to feature its Lamellar 3D titanium technology.

Capri Small 3D Static is designed to help surgeons stabilise the thoracolumbar spine (T1 to L5) in cases of vertebral body resections resulting from trauma or tumour. Its porous structure and rough surface architectures are designed to allow for bony integration throughout an implant. The system’s lordotic options help support the anterior spinal column with the goal of achieving sagittal balance.

“Capri Small 3D Static provides me with a corpectomy cage that incorporates the Lamellar 3D Titanium Technology to treat patients with complex pathologies,” says Michael Finn, a neurosurgeon and assistant professor in the Department of Neurosurgery at the University of Colorado, Denver, USA. “The incorporation of pores into the endplates increases the surface area for fusion and presents the potential for bone to grow into the corpectomy cage.”

K2M’s Lamellar technology uses an advanced 3D printing method to create structures that are impossible with traditional manufacturing techniques. Starting with a titanium powder, the Capri Small 3D Static corpectomy cages are grown through the selective application of a high-energy laser beam, incorporating complex internal geometries and rough surface architecture that pre-clinical data have associated with bone growth activity. Lamellar technology incorporates a porous structure along with rough surfaces to allow the potential for bony integration throughout the cage.
