Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Medical Technology

Background:

  • Spine surgery is advancing with robotic systems enhancing techniques and patient outcomes.
  • Evaluating the added value and cost-effectiveness of integrated robotic technologies is crucial.

Purpose of the Study:

  • To compare surgical efficiency between robot-assisted and navigation-based spine surgery.
  • To analyze operative duration, blood loss, and hospital stay for different fusion procedures.

Main Methods:

  • Retrospective cohort study at a single center.
  • Patients underwent single- and double-level transforaminal lumbar interbody fusion (TLIF) and oblique lumbar interbody fusion (OLIF).
  • Comparison of robot-assisted versus navigation-based surgery groups, stratified by procedure type and fusion levels.

Main Results:

  • Robot-assisted surgery showed statistically significant reductions in operative duration for one- and two-level OLIF (50 and 62 min savings).
  • Estimated cost reduction of SGD 1500 per patient for two-level OLIF, with potential for higher savings.
  • No significant difference in blood loss or length of hospital stay was explicitly stated as a primary finding.

Conclusions:

  • Robot-assisted spine surgery demonstrates superior efficiency and cost-effectiveness, particularly for multi-level procedures.
  • The integration of evolving robotic technologies in spine surgery is justified for improved patient outcomes.
  • The findings support the adoption of robotic systems for enhanced surgical performance and economic benefits.
