Hypertrophic Nonunion Humerus Mimicking an Enchondroma

Abstract EN

Introduction.

Although fractures of humeral shaft show excellent results with conservative management, nonunion does occur.

Case Report.

We bring forth the case of a young male with a 1.5-year-old hypertrophic nonunion of the humerus mimicking an enchondroma.

The initial X-ray images of the patient appeared to be an enchondroma, which only on further evaluation and histopathological analysis was diagnosed conclusively to be a hypertrophic nonunion.

Discussion.

Enchondromas are often incidentally diagnosed benign tumours.

It is however not common to misdiagnose a hypertrophic nonunion to be an enchondroma.

We present this case to highlight the unique diagnostic dilemma the treating team had to face.
