INTRODUCTION:
Ankle fractures are common injuries that could result from a trivial twisting injury in old frail patients up to high energy trauma in a young population. Ankle fractures represent 10 % of all fractures making these the second most common lower limb fractures after hip fractures.
Open reduction and internal fixation is the management of choice for bimalleolar ankle fractures. Lateral malleolus fractures are fixed by either by plate or long cortical screw. The debate is ongoing about the best fixation method for vertical shear medial malleolus fracture either by lag screws or buttress plate as they are biocmechanically different in their strength of fixation.
Lag screws offers good advantage of smaller incision and less prominent metal work.
Buttress plate offers good advantage of more mechanical stable rigid fixation.

AIM OF THE WORK:
The aim of this study was to compare between the results of lag screws fixation versus buttress plate in vertical shear medial malleolar ankle fractures.
