4WEB Truss Cage System

Patient Specific ImplantsTreating patients with significant bone loss can be an exacting challenge. Even though techniques have evolved and a number of treatment options are now available that utilise either external or internal fixation and some form of bone graft they are not without potential complications.

‘The advent of 3D printing ushers in an era of even more customisable patient specific implants with seemly limitless size, shape, and material options, thus opening a new frontier for reconstructive efforts in patients previously relegated to complex limb salvage or amputation’ 1.

The recent introduction of additive manufacturing techniques, also known as ‘3D printing’, into the production of medical devices has opened up the possibility of designing and manufacturing implants which closely match a patient’s anatomy. In clinical situations where significant osseous deficits are present patient specific implants can be designed to include the areas of bone loss to restore natural anatomy. With the patented 4WEB Truss System, an implant can be designed which combines an inherent strength with even load distribution for early patient mobilisation. The construct offers a high level of porosity to accommodate bone graft material. This combination of strength, load sharing and open architecture has been designed to promote bone fusion.

Unlike traditional custom devices, which often have lengthy lead times, the 3D printing techniques result in a short lead time for the production and delivery of the patient specific device.

The patient specific 4WEB implants can be used in Trauma, Tumour, Limb Reconstruction or Fusion applications.

“It is therefore plausible that nanorough regions of titanium surfaces with sharp edges and spikes promote the adhesion of osteoblasts’3.

Truss structure combines strength with even load distribution through the cage and apposing bone.

Open architecture ensures that up to 75% of the cage can be filled with bone graft material.

Additive manufacturing - 3D Printing- ensures that custom implants can

be produced to precisely match complex patient anatomies,

including osseous deficits.

The bone formation is highly organized, stable and hastens the deposition of structural lamellar bone in a very short time’2.

The cage is fabricated from medical grade Titanium alloy using Electron Beam Melting. A proven orthopedic implant material.

The ordering process for a Patient Specific Implant is straightforward and has 6 main steps. As this device is designed and manufactured to match each patient’s unique anatomy a custom prescription will need to be signed by the prescribing physician.

OrthoSolutions would supply the custom device to the hospital 5 weeks from the sign off of the design by the prescribing surgeon and the receipt of the purchase order.
