[[Robotic systems]] in [[spine surgery]] have emerged as powerful [[tool]]s that enhance the surgeon's capabilities, improve [[safety]], and [[support]] [[minimally invasive]] approaches.

===== 🤖 Main Robotic Systems Currently in Use =====

[[Mazor]]X and Mazor X Stealth Edition (Medtronic)

Based on preoperative planning and intraoperative guidance.

Often used for [[pedicle screw placement]].

Integrated with [[Medtronic]]'s navigation platform.

[[ExcelsiusGPS]] (Globus Medical)

Combines navigation and robotics in a single platform.

Allows for real-time visualization of instrumentation.

[[ROSA Spine]] (Zimmer Biomet)

Used for minimally invasive screw placement.

Includes a planning module and intraoperative adaptation.

[[Cirq]] (Brainlab)

Robotic arm integrated with Brainlab navigation.

Less autonomous, more like a robotic guide.

[[TianJi Robot]] (Tinavi Medical)

Developed in China and approved for clinical use in Asia and Europe.

Used in complex spine and pelvic procedures.

⚙️ Key Features & Advantages
Preoperative Planning: Simulates and optimizes screw trajectories.

Precision: Sub-millimeter accuracy, particularly for pedicle screws.

Reduced Radiation: Less reliance on intraoperative fluoroscopy.

Minimally Invasive Access: Smaller incisions, less muscle dissection.

Shorter Hospital Stays: Faster recovery and mobilization.

Consistency: Particularly useful for less experienced surgeons.

🧠 Limitations and Challenges
Cost: High acquisition and maintenance costs.

Learning Curve: Requires specialized training and adaptation of workflow.

Setup Time: Can increase total operative time initially.

Limited Autonomy: Most systems are robotic-assisted, not fully autonomous.

Integration Issues: Compatibility with hospital IT systems and imaging modalities.

📊 Evidence and Outcomes
Accuracy: Multiple studies show improved screw placement accuracy (up to 98–99%).

Complication Rates: Tend to be lower in robotic-assisted procedures.

Surgical Time: May be longer at first, but improves with experience.

Patient Satisfaction: Generally high due to lower postoperative pain and faster recovery.

🔮 Future Directions
AI Integration: To improve planning, prediction of outcomes, and error prevention.

Haptic Feedback: Robotic systems with tactile sensation for the surgeon.

Augmented Reality: For enhanced intraoperative visualization.

Remote Surgery: Telerobotic capabilities under investigation.

Expanded Indications: Use in tumor resections, deformity corrections, and spinal cord stimulation.

===== Narrative Reviews =====

A [[narrative_review|narrative review]] explores the state of robotic systems in [[spine_surgery|spine surgery]], focusing on the feasibility of full automation. The authors assess existing technologies like Cirq®, Mazor X™, and ExcelsiusGPS™, specifically focusing on trajectory-guidance mechanisms and tracking systems
((Samprón N, Lafuente J, Presa-Alonso J, Ivanov M, Hartl R, Ringel F. Advancing spine surgery: Evaluating the potential for full robotic automation. Brain Spine. 2025 Mar 17;5:104232. doi: 10.1016/j.bas.2025.104232. PMID: 40191588; PMCID: PMC11968298.)). 
Their central research question examines both the current capabilities and limitations of robotics in the surgical field and the technological leaps required for progressing toward automation.

Critical Analysis:

The review is structured around a comprehensive examination of available robotic tools, offering a well-balanced discussion of both their promises and shortcomings. It highlights a crucial distinction: while robotic assistance is advancing, autonomy remains elusive. The discussion of tracking technologies is especially valuable, comparing traditional [[optical_tracking|optical tracking]] to emerging [[encoder_based_systems|encoder-based systems]], the latter showing enhanced reliability and accuracy.

However, as a narrative review, the methodology lacks systematic rigor. Selection criteria for the included literature are not explicitly defined, limiting reproducibility and potentially introducing bias. In contrast, a [[systematic_review|systematic review]] might have offered more transparency and breadth in data selection and interpretation.

The review convincingly argues that despite progress, full robotic automation faces significant hurdles. The authors correctly identify that [[human_decision_making|human decision-making]] is not easily replicable in the surgical context, particularly in the face of anatomical variability and intraoperative complexity.

Strengths:

Clear synthesis of technical challenges in robotic spine surgery.

Forward-looking perspective on encoder-based systems.

Realistic assessment of the limits of current technologies.

Limitations:

Narrative format limits methodological rigor.

Lack of quantitative comparison or meta-analytical components.

Underrepresentation of ethical and medico-legal implications of automation.

Conclusion:
This article provides an insightful update on the status and direction of robotic innovation in spine surgery. While it underscores the unrealized goal of full automation, it offers a hopeful trajectory of increasing robot-surgeon collaboration. The piece is a useful resource for understanding where the field stands and what technological and philosophical obstacles must be overcome.
