Spine Surgery & Devices

Spine surgery instrumentation includes pedicle screw systems, interbody fusion cages, artificial disc replacements, and minimally invasive access systems used in procedures ranging from single-level cervical fusions to complex adult deformity corrections. The U.S. spine device market generates approximately $14 billion in annual revenue, driven by an aging population, rising rates of degenerative disc disease, and rapid adoption of MIS and robotic-assisted techniques. This resource center covers the instrumentation, technology, and clinical decision-making behind modern spine surgery.

Frequently Asked Questions

What are the most common types of spinal fusion procedures?

The four primary fusion approaches are ALIF (anterior lumbar interbody fusion), PLIF (posterior lumbar interbody fusion), TLIF (transforaminal lumbar interbody fusion), and XLIF/LLIF (lateral lumbar interbody fusion). Each approach uses different instrumentation and access corridors. TLIF is currently the most widely performed lumbar fusion technique in the U.S. because it provides 360-degree fusion through a single posterior incision. Cervical fusions most commonly use the anterior approach (ACDF) with a plate and cage construct.

What is the difference between pedicle screws and cortical screws in spine surgery?

Traditional pedicle screws enter through the pedicle and anchor in the vertebral body’s cancellous bone. Cortical bone trajectory (CBT) screws follow a medial-to-lateral path that engages denser cortical bone along the pedicle’s walls. CBT screws require smaller incisions and less muscle dissection, making them popular in MIS approaches. They also provide strong fixation in osteoporotic bone where traditional pedicle screws may not achieve adequate purchase. The trade-off is a steeper learning curve and limited use in complex deformity constructs.

How are spine surgery devices different from general orthopedic implants?

Spine instrumentation is designed for the unique biomechanics of the vertebral column — axial loading, multi-directional flexibility, and proximity to the spinal cord and nerve roots. Spine devices require sub-millimeter placement accuracy (especially in the cervical spine), which drives adoption of navigation and robotic platforms. The implant systems are also more modular than general orthopedic hardware, with surgeons assembling custom rod-screw constructs intraoperatively based on patient anatomy and pathology. Regulatory pathways and surgeon training requirements differ significantly from trauma or joint replacement devices.
