The medial approach to the subtalar joint allows good visualization of the articular surfaces. Compared with the lateral approach, advantages are found particularly in flatfoot correction, in which the single-incision technique can be used for corrective fusions of rigid flatfoot deformity. Union rates are comparable with the traditional lateral approach; however, wound healing problems occur less frequently. Avascular necrosis of the talus is a rare but serious complication, although frequency seems to be independent of the approach chosen. Clinical studies showed no increased morbidity when comparing the medial to the lateral approach.
