The research aims to compare the postoperative anatomical restoration of dorsal and volar fixation in distal oblique scaphoid fractures using CT imaging.
Retrospective review of Herbert B1 fractures treated with percutaneous screw fixation over 10 years.
Standardized dorsal and volar fixation protocols implemented with fluoroscopic guidewire placement.
Postoperative CT assessed height-to-length ratio, intrascaphoid angle, and dorsal cortical angle.
Comparison of demographic, injury, operative characteristics, and clinical outcomes between the approaches.
The dorsal approach cohort had a lower height-to-length ratio (0.64) compared to volar (0.70), indicating better restoration.
No significant differences in demographic or operative characteristics between the two cohorts.
Dorsal approach patients reported significantly lower Disability of the Arm, Shoulder, and Hand scores at follow-up (17.7 vs 45.5).
Two patients developed nonunion, both treated with the dorsal approach.

Implication

This retrospective analysis examines anatomical outcomes of dorsal vs volar fixation in scaphoid fractures, suggesting potential benefits of dorsal fixation.
