Description
Abhishek Soni and co-authors describe a positioning trick that fixes imaging registration failures during robot-assisted spine surgery in very heavy patients. Standard reference markers can fall outside the scanner's field of view when body mass is high, stalling the operation. Their series covered sixty-three patients with body mass index above forty, treated between October 2023 and November 2024.
Placing the marker on the patient's side, exploiting the scanner's wider sideways coverage, was used in seventeen cases. No patient with lateral placement needed repeated registration attempts, while a few standard-placement patients needed two or more. Registration ultimately succeeded in every case, and screw placement accuracy stayed equally high under both approaches. Repeat attempts, when they happened, added scanning time and radiation dose. The authors note the fix needs no new equipment, only a change in marker position guided by a quick preliminary scan.
