Assessment of percutaneous intramedullary screw fixation in lateral malleolar ankle fractures
Purpose: To evaluate the outcome of using percutanous intramedullary screw and its efficacy on fixation of lateral malleolar ankle fractures. Methods and Materials: Twenty five patients with Weber A and Weber B displaced lateral malleolus fractures were retrospectively reviewed after they had done closed reduction and percutaneous internal fixation with an intramedullary fully threaded screw with a washer. A 3.5 mm, fully threaded, selftapping bone screw. The length of the screw varies between 90 mm and 110 mm, depending on the fracture location and pattern. Results: All fractures united within an average time to union of 5.86 1.74 weeks. There were no deep wound infections or complaints of painful hardware. At latest follow up, functional results were excellent in 16 patients (64% good in 8 patients (32 fair in one patient (4% Conclusion: Percutaneous intramedullary screw fixation is a good easy technique in management of lateral malleolar fracture that provides good clinical and radiological results as it is rapid, minimally invasive and without prominent hardware.
