Evaluation of contact area and pressure after malreduction in isolated medial malleolar fractures with 2mm of displacement: a cadaveric study

This study was performed to evaluate the changes in contact area and pressure in the tibiotalar joint, with a 2 mm displacement after IMMF(isolated medial malleolar fracture). Ten cadavers with pairs were used to establish a situation in which IMMF occurred during ankle injury. We performed IMMF corresponding to types C and D of the Herscovici classification, and it was displaced by 2 mm. The normal group was defined as a normal tibiotalar joint, the TF(transverse fracture) group as a 2 mm transverse displacement corresponding to the Herscovici classification type C, and the OF(oblique fracture) group as a 2 mm oblique displacement corresponding to the Herscovici classification type D.
