Abstract
This study reports the technique, efficacy and safety of robotic-assisted, computer-navigated, percutaneous fixation of scaphoid fractures. Ten males with acute undisplaced waist fractures underwent fixation with this method using a commercially available three-dimensional fluoroscopy unit and robotic navigation system. The mean total operative duration was 40 minutes, which comprised of a set-up time of 18 minutes and planning and surgical time of 22 minutes. All patients required only a single guidewire insertion attempt, and there were no screw protuberances or other complications. All fractures united at a mean of 8weeks. At a mean follow-up of 6.5months (range 6-8), the mean Mayo wrist score was 96, patient-rated wrist evaluation was 2, flexion-extension arc was 96% and grip strength was 91% of the contralateral side. We conclude from our patients that robotic-assisted percutaneous scaphoid fixation is feasible, safe and accurate, and is a satisfactory method for treating these injuries. Level of evidence: IV.
