Percutaneous fixation of acute scaphoid fractures: a retrospective study

Authors

Abstract

Objective
The aim of this study were to determine whether the functional outcome of the evaluation of the effectiveness of percutaneous retrograde (volar) approach of insertion of cannulated Herbert's screw to stabilize acute scaphoid fractures and to evaluate the functional outcome after this minimally invasive operative management of this problematic fracture.
Background
Scaphoid fracture is the most common carpal fracture. It accounts for ∼60–90% of carpal and 11% of hand fractures. Scaphoid fracture is a common fracture affecting mainly young active people during their work or while participating in sports activities.
Patients and methods
This is a retrospective observational study of patients undergoing surgery for percutaneous fixation of acute scaphoid fracture. In our study, 12 patients with less than 14-day-old fractures were fixed percutaneously by Herbert's screw and reviewed for a minimum of 12 months (average of 24 months). The functional outcome of this method was assessed.
Results
Fracture union was achieved in 11 (91.6%) cases at a mean of 8.29 weeks (6–12 weeks), whereas one case was ununited.
Conclusion
This study proves that fixation of acute scaphoid fractures results in predictable satisfactory union rate and functional outcome. Moreover, it proves that percutaneous Herbert's screw insertion carries no risk of damage to soft tissues or vascular supply.
