Heterotopic Ossification of Left Hip after Sport Injury; Imaging Techniques and Features in Early and Late Presentation

Aim: This report is aimed at highlighting the plain film features in late presentation of heterotopic ossification and other imaging features as well as raise awareness about heterotopic ossification, an uncommonly diagnosed and neglected sequalae of traumatic injuries in Nigeria.

Presentation of Case: A 43-year old man who had been experiencing post recreational sport recurrent dull pain and worsening limitation of movement in his left hip following an initial sports injury he sustained three years before presentation.

Discussion: Plain radiograph features were consistent with matured heterotopic ossification of the left hip. This was observed in the 4th decade of life though commoner in younger people.

Conclusion: Plain film is still a useful modality in the evaluation of matured heterotopic ossifications. It should be considered among differential diagnosis of recurrent joint pain following history of trauma by attending physicians, to prevent the possible sequalae of improperly treated traumatic joint injuries, to aid early treatment and avoid long term complications
