Bone deficiency

Bone deficiency

The articular surface of the os calcis is impacted by the talus into the underlying cancellous bone. Once the articular fragments are disimpacted and elevated, varying degrees of void result.
Studies show that bone graft is not necessary, yet some surgeons fill the void with bone substitute materials, and other surgeons choose to ignore the void and use locking plate fixation to maintain reductions.
