Results of Percutaneous Fixation of Acute Scaphoid Fractures by Herbert Screw

Abstract

Background: The Scaphoid bone is the tmost commonly fractured carpal bone. Proper clinical examination and radiological imaging is essential for early diagnosis and management. The management of scaphoid fractures varies from cast immobilization to open reduction and internal fixation. This paper explores the outcome of using headless cannulated screws in minimally displaced scaphoid fractures. Objective: Aim of this study is to assess the functional and clinical outcome of using cannulated headless screws in management of acute scaphoid fractures. Methods: A prospective study held between February 2019 and January 2020, where eighteen patients included with acute scaphoid fractures of Herbert B1, B2 and B3 classification. Fixation was done using both volar and dorsal percutaneous technique. Patients were evaluated postoperatively clinically using modified Mayo wrist score (MMWS). Results: Of mean age 34.5±8.37 years, the majority were with excellent final outcome (83.3%), good (5.6%), fair one case (5.6%) and only one poor (5.6%) and mean time of union was 9.66±1.9 months. Conclusion: All active young individuals with acute non-displaced or minimally displaced scaphoid fractures should be offered percutaneous internal fixation, for the sake of earlier gain of motion of the wrist, earlier time to union, quicker return to activity of daily living, and a lower complication rate.
