Bilateral trochlear avascular necrosis: A case report and brief review of the literature.

INTRODUCTION AND IMPORTANCE

Trochlear AVN is a very rare entity with only a limited number of cases being reported.

CASE PRESENTATION

Our case is interesting as it presents a case of an incidentally found bilateral trochlear AVN in a 12 year-old child when he presented with an undisplaced right supracondylar fracture.

CLINICAL DISCUSSION

It is highly likely that an unknown underlying predisposing factor, possibly recurrent microtrauma, was responsible for the bilateral occurrence.

CONCLUSION

We recommend further research to identify other etiological and predisposing factors, as the etiological factors still remain unclear, despite the available literature.
