The treatment of perilunate injuries remains challenging and contentious. This study aims to describe a novel mini\u2010invasive surgical technique of arthroscopic\u2010assisted reduction and robot\u2010assisted fixation for the treatment of trans\u2010scaphoid perilunate fracture dislocations (PLFDs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively reviewed patients with PLFDs after surgical treatment from February 2021 to March 2021. The patients underwent arthroscopic\u2010assisted precise reduction and robot\u2010assisted headless screw fixation. Times of guide wire placement were recorded intraoperatively. Periodic follow\u2010up was performed until union of scaphoid fracture was confirmed. Range of motion of the wrist, grip strength, the Visual Analog Scale (VAS) score, the Mayo Wrist Score, the Quick Disabilities of Arm, Shoulder, and Hand (QuickDASH) score, the Patient\u2010Rated Wrist Evaluation (PRWE), and osteoarthritis were evaluated at the final follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Two male patients presenting with PLFDs with an average age of 24.5\u2009years old (32 and 17\u2009years) were included in this study. Intraoperatively, anatomic reduction of the scaphoid fracture was achieved under arthroscopic guidance. A robotic\u2010assisted single\u2010attempt guidewire insertion was performed for scaphoid fracture and lunotriquetral interval. The CT scans at 8 and 12\u2009weeks showed the union of the scaphoid fracture. At final mean follow\u2010up of 13.5\u2009months, the extension, radial\u2010ulnar deviation, and pronation\u2010supination were consistent with the contralateral side in both patients. One patient experienced mild limited range of motion with the flexion 46\u00b0 of the injured wrist compared with 81\u00b0of the contralateral wrist. The VAS score was 0 and 2. The grip strength was 32 and 26 kg compared with 24 and 42 kg of the contralateral wrist. The PRWE score was 13 and 10 and the QuickDASH score was 2 and 7. The Mayo Wrist Score was 100 and 65.
