Abstract

 A retrospective study has been carried out to assess the effectiveness of indomethacin in preventing heterotopic ossification after total hip arthroplasty, and the effect of using it for different periods of time. One hundred and sixty-eight hips operated on in 1983 were not given indomethacin and acted as a control. One hundred and fifty hips operated on in 1988 were given indomethacin and divided into 3 groups: 42 received indomethacin for 5 days, 49 for 11 days and 59 for 45 days. The results indicate that ossification is significantly reduced in those patients receiving indomethacin for 5 and 11 days, but there was no additional reduction when it was given for 45 days. Treatment should begin on the night of operation and continued for 11 days while the patient remains in hospital.
