Why does navigation accuracy matter for implant placement?

Scientific Value: Enables mechanistic evaluation of spinal stabilization strategies under physiologically relevant load-bearing conditions.
Operational Value: Provides a reproducible model for testing biomechanical performance of interbody implants and fixation systems.

Navigation accuracy ensures precise targeting of the disc space and safe trajectory through the psoas muscle, reducing risks to neurovascular structures and enabling optimal cage positioning for spinal stabilization.

How does direct psoas muscle visualization support procedural safety?

Direct visualization allows controlled dissection of the psoas muscle under guidance, minimizing the chance of inadvertent peritoneal entry or injury to the femoral and lateral femoral cutaneous nerves.

What enables simultaneous anterior and posterior spine access?

The prone single-position approach on an open Jackson table allows surgeons to perform posterior decompression and pedicle screw placement followed by lateral interbody cage insertion without patient repositioning.

Why is retractor system placement superficial to the psoas important?

Placing the retractor system superficial to the psoas maintains an open surgical corridor while protecting the lumbar plexus and enabling direct visualization of the disc space for cage preparation and insertion.

What role does intraoperative neuromonitoring play in this procedure?

Intraoperative neuromonitoring with lower extremity electromyography helps detect neural irritation during dissection, allowing real-time adjustments to prevent permanent nerve injury.
