Neurosurgery: patient-specific cranioplasty and planning of cranial reconstruction

We design PEEK and titanium cranial plates, surgical guides and anatomical models from the patient's CT data.

What we manufacture

What Bonabyte designs for neurosurgery

Patient-specific perforated PEEK cranial plate

PEEK cranial plate

Radiolucent, producing no artefacts on CT or MRI. Thickness and curvature follow the patient's own vault.

Titanium cranial plate with a mesh structure

Titanium cranial plate

Strength under load, a mesh structure and a precise fit to the defect margins.

How the process works

From CT to plate

1

CT of the defect

Full coverage of the defect and the healthy side for mirroring.

2

Segmentation and model

3D skull model, construction of the plate geometry.

3

Approval

Shape, thickness, holes and fixation points — before manufacturing.

4

Manufacturing and delivery

Plate, guide and model — delivered to the clinic.

FAQ

FAQ

Patient-specific cranial plates in PEEK and titanium alloy, surgical guides and templates, and anatomical skull models. Details on cranioplasty are on a separate page.

PEEK is radiolucent and usually makes postoperative imaging follow-up easier; titanium is stronger and allows porous structures and complex geometry. The choice is determined by the clinical task and the physician's decision.

MSCT with full coverage of the defect and the healthy contralateral side for mirroring, primary axial DICOM. Details are in the CT protocols section.

What you should know

Limits of what is possible

Bonabyte designs and manufactures the device according to the treating physician's plan. Medical decisions are made by the surgeon.

What we can do
  • reconstruct the geometry of the cranial vault defect from the CT
  • design a patient-specific plate
  • agree the thickness, contour, perforation and fixation
  • manufacture the device from a material suited to the task
  • provide an anatomical model or a guide, where the project calls for it
What we cannot determine without the physician and the source data
  • the medical indications for surgery
  • surgical access
  • whether a particular material is acceptable
  • soft tissue condition
  • the final fixation method
  • the prognosis of the clinical outcome

A complex cranial defect?

Send us a CT — an engineer will build the model, select the material and prepare the plate with a guide.

The information on this website is intended for healthcare professionals and does not constitute medical advice, a public offer or a guarantee of clinical outcome. Bonabyte devices are custom-made medical devices designed for a specific clinical task; their applicability depends on the CT data, the anatomy, the condition of the soft tissues, the surgical access and the operative plan. The final decision on the use of a device is made by the treating physician. Contraindications exist and an individual assessment of the clinical situation is required.
