Evaluation of the Results of Antiglide Plating of Vertical Medial Malleolus Fractures

Abstract

Background: Vertical fractures of the medial malleolus are fixed with cancellous screws placed perpendicular to the fracture site. It is important to buttress the fracture by placing a screw with a washer at the proximal apex of the fracture or to use a small tubular plate or T-plate as a buttress. Objective: To assess the radiological and functional outcomes of open reduction and internal fixation with T-shaped plate (antiglide plate) of vertical shear medial malleolus fracture. Patients and Methods: This was clinical trial study included 22 adult patients with vertical shear medial malleolus fracture who were admitted to Orthopedic Surgery Department, Zagazig University Hospitals in the period from January 2019 to February 2020. They were treated by internal fixation with T-shaped plate (antiglide plate). In this study, we used the Biard and Jackson ankle scoring for assessment of result. Results: The union duration was 12.1± 2.2 weeks ranged from 9 to 16 weeks, most of the studied group (59.1%) had healing time ranged from 9 to 12 weeks. No complications and only two patients (9.1%) had superficial infection with no other complications. Biard and Jackson score was 95.3 ± 4.9 ranged from 76 to 98. Most of the studied group (68.2%) had excellent outcome, 22.7% of them had good outcome and 9.0% had poor outcome. Conclusions: Surgical management of vertical shear of medial malleolus fracture give excellent anatomical reduction and rigid fixation to restore articular congruity, help to facilitate early mobilization and hence to achieve optimal ankle function.
