Abstract
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, self- tapping 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.
