Fully threaded headless compression screw versus partially threaded cancellous lag screw in medial malleolus fractures: clinical and radiological outcomes

The aim of this study was to evaluate the clinical and radiological results of medial malleolar fractures, which were treated with fully threaded headless compression screws and to compare the clinical and radiological results of this screws and partially threaded cancellous lag screws.
Sixty-one patients who attended the final follow-up examination were included in the study. Group 1 comprised 29 patients applied with fully threaded headless compression screws and Group 2 comprised 32 patients with partially threaded cancellous lag screws. Radiological evaluation was made with standard radiographs. The clinical evaluations were applied using the AOFAS ankle hindfoot scale. Pain or sensitivity by touching over the medial malleolus was recorded and scored according to Visual Analog Scale.
No significant differences were determined between the groups with respect to age, gender, fracture type, follow-up time, bone union time and AOFAS scores. The medial sensitivity associated with implant irritation was significantly lower in Group 1. There was no need for removal of the fixation material in any patient of Group 1.
The results of this study showed satisfactory results in the two fixation techniques in medial malleolar fractures. However, the rates of medial sensitivity associated with implant irritation were lower in the group where fully threaded headless compression screws were used. Therefore, to prevent postoperative patient dissatisfaction caused by persistent medial sensitivity associated with implant irritation, despite successful surgical treatment, the primary choice may be fully threaded headless compression screws.
