Protocol ALIF Spine Surgery
Platform Meta Quest / Unity

We architected a zero-risk virtual operating theater, allowing students to practice complex spinal fusion mechanics with haptic precision before touching a patient.

Anatomy is Not Abstract.

Medical diagrams are flat. Surgery is spatial. A Biomedicine student needed to bridge this gap for their thesis on Anterior Lumbar Interbody Fusion (ALIF).

The requirement was not just "seeing" the surgery, but performing it. The system needed to simulate the physical constraints of implant alignment, incision depth, and instrument handling—all running smoothly on a standalone headset.

Iterative Simulation

We treated the human body as a rigid-body physics environment.

1. Environmental Optimization

High-fidelity anatomical models (millions of polys) were retopologized into performant game-ready assets without losing medical accuracy.

2. Mechanics Programming

We scripted interaction layers for specific tools: Scalpels cut, retractors pull (using vertex displacement), and implants snap to grid only when aligned perfectly.

3. User Guidance System

A non-intrusive UI was architected to guide the trainee through the steps, turning a sandbox chaos into a structured educational curriculum.

"Riad and the team delivered a functional prototype covering the crucial steps for my project. Their dedication was invaluable."
