[Complications following subchondral, not intra-articular, injections of corticosteroids]

The author describes two cases of bone changes following non-intra-articular and more probably sub-chondral injection of corticosteroids. The first, in condyle a mandibular was reversible with reconstruction of the bone after a year. The second, in the condyle of a knee was definitive with a permanent chip in the bone.
