Application and Evaluation of an Independent Robotic Arm System in K-wire Placement for Lumbar Fusion

The objective of this study was to introduce a novel robotic system with an independent arm (“Orthbot Intelligent Orthopedic Minimally Invasive System”; Xin Junte Surgical Technologies) that has been developed and tested as a surgical assistant for autoplacement of the Kirschner wire (K-wire) in lumbar fusion, and to evaluate its accuracy by comparing it with the conventional free-hand instrumentation.

Summary of Background Data:

Robotic technology has performed excellently in spine surgeries and has demonstrated high clinical value and potential. Robot-assisted spinal surgery is now being promoted as a paradigm for technology-led advancement.

Materials and Methods:

A total of 24 patients were recruited and assigned randomly to the robotic arm group (RG) or the free-hand group (FG). Deviation distance and deviation angle (DA) of K-wire placement were measured and compared between the RG and the FG.

Results:

The average deviation distance was 0.88±0.08 mm in the RG and 5.13±1.68 mm in the FG (P
