Abstract

To investigate the feasibility and the clinical efficiency of robot navigation combined with wrist arthroscopy in minimally invasive treatment of nondisplaced type Herbert D1 scaphoid fracture. A retrospective analysis was performed on 9 patients who underwent nondisplaced type Herbert D1 scaphoid fracture in Xuzhou Renci Hospital from December 2019 to January 2021. Before the operation and at the last follow-up, grip strength, pinching force, modified wrist Mayo score and visual analogue scale (VAS) of wrist pain were recorded and compared. The average follow-up time was 14.1 months (7.5-24.0 months). All the fractures achieved primary healing after an average of 13.3 weeks (10-18 weeks). The average flexion and dorsal extension activity of the injured wrist was 51.2°±9.4°, 68.0°±7.3°, and the radial and ulnar deviation was 19.3°±6.2°, 45.7°±7.8°, respectively. At the final follow-up, there were statistically significant differences in grip strength, pinch strength, wrist Mayo score and VAS when compared with those before the operation (all P<0.05). The results demonstrated that robot navigation combined with wrist arthroscopy for nondisplaced type Herbert D1 scaphoid fracture is effective and minimally invasive with a short recovery time and satisfactory healing rate.
