Abstract:
Background: Several devices have been described for fixation of displaced medial malleolar fractures. Fullythreaded cancellous screws engaging the bone may provide advantages compared to partially threaded screws.This study was designed to compare the clinical results of fully and partially threaded 4 millimeter cancellousscrews in fixation of medial malleolar fractures.Methods: In a randomized clinical trial study 44 patients with displaced closed medial malleolar fractures wererandomly divided into two groups. Two fully threaded four millimeter cancellous screws were used for fracturestabilization (FT group) in the first group, while, the second group was operated by use of two partially threaded fourmillimeter cancellous screws (PT group). The clinical outcomes and complications were compared in two groups atone year follow up.Results: Nineteen patients in FT group and 21 in PT group were present at final follow up. Nonunion was notdeveloped in either group but two cases (9%) of delayed union occurred in PT group. The rate of postoperativeinfection and symptomatic hardware were not statistically different. Functional assessment using AOFAS, MOXFQand VAS scores showed no significant difference between the two groups.Conclusion: Both fully and partially threaded 4 mm cancellous screws can be considered as acceptable devices forthe fixation of medial malleolar fractures with good and comparable clinical results.Level of evidence: I
