Indomethacin Prophylaxis for Heterotopic Ossification After Surgical Treatment of Elbow Trauma

This study is currently recruiting participants. (see Contacts and Locations)

Patients who present to our institution with a traumatic injury to their elbow who need operative management will be randomized to one of two groups; a treatment arm and a control arm. The treatment arm will receive a three-week postoperative course of indomethacin while the control group will not. We will follow both groups to assess whether or not indomethacin prophylaxis affects the rate of heterotopic ossification.

Primary Outcome Measures:
  • change in post operative radiographic evaluation [ Time Frame: 6 weeks and 3, 6 and 12 mfup ]
    AS a standard care patients will be routinely assess at three, six , twelve and twenty four months post-operatively.

Secondary Outcome Measures:
  • change in range of motion [ Time Frame: 6 weeks and 3, 6 and 12 mfup ]
    measuring range of motion with a goniometer will be performed at 6 weeks and 3, 6 and 12 mfup

  • Patient Rate Elbow Evaluation [ Time Frame: 6 weeks and 3, 6 and 12 mfup ]
    is a 20-item questionnaire designed to measure elbow pain and disability

  • The Mayo Elbow Performance score [ Time Frame: 6 weeks and 3, 6 and 12 mfup ]
    is an instrument used to test the limitations to use the elbow during ADL caused by the pathology

  • Disabilities of the Arm, Shoulder and Hand [ Time Frame: 6 weeks and 3, 6 and 12 mfup ]
    is a 30-item, self-report questionnaire designed to measure physical function and symptoms in people with any of several musculoskeletal disorders of the upper limb.

Estimated Enrollment: 150
Study Start Date: November 2012
Estimated Study Completion Date: November 2019
Estimated Primary Completion Date: November 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: drug
The treatment arm will receive 21 days of Indomethacin and Pantoprazole (gastrointestinal protective agent). The patients will receive Indomethacin 25mg three times a day and Pantoprozole 40mg once a day.
Drug: Indomethacin and Pantoprazole
Placebo Comparator: placebo
The placebo group will receive microcrystalline cellulose powder tablets to be taken as a control. The placebo will be dosed at the same intervals and duration as the treatment arm in this study.
Drug: microcrystalline cellulose powder tablets
