Spinal Fusion Device

Case Study


The Problem

For fractured and compressed vertebrae, orthopedic surgeons rely on prostheses and bone cement to stabilize the area and relieve pain. These techniques can lead to a variety of complications.

The Solution

Flexispine, a Maryland-based medical device technology company focused on motion restoration, stabilization, and endoscopy, sought a new type of lumbar and cervical prostheses to improve spinal procedures. Rather than creating a prosthesis that adheres directly to the spine, Flexispine is attached to lateral extensions, which are in turn secured by sacral screws.

Flexispine engaged Smithwise to provide the mechanical engineering and functional prototyping of the lumbar and cervical prostheses.

This process involved importing anatomical spinal geometry and developing 3-D mechanical geometries to meet a wide spectrum of bone shapes and sizes.

With a patent secured and a functional prototype in place, Flexispine is currently in discussion with orthopedic companies to bring their product to market.

The occurrence of chronic back pain in patients aged 45 to 60 has increased by 64% in recent years. The costs associated with treatment are over $40 billion and are expected to continue to rise.
