Abstract
BACKGROUND
Bone marrow edema (BME) is a common cause of hip pain. The aim of the study was to assess the efficacy of the vasoactive drug iloprost in the treatment of BME of femoral head.
MATERIALS AND METHODS
We reviewed 27 patients (19 male, 8 female) with BME of the femoral head. Their mean age was 53.7 +/- 10.8 years. All patients were treated with iloprost, a vasoactive drug that dilates arterioles and venules, reduces capillary permeability and suppresses platelet aggregation. The therapy comprised a series of five infusions with 20 to 50 mug iloprost over 6 h on 5 consecutive days each. Weight bearing was reduced for up to 3 weeks, depending on the severity of symptoms. Pain at rest as well as under stress was assessed with a semi quantitative scale from before and 4 months after therapy. MRI investigations were done before and repeated 4 months after therapy.
RESULTS
At the clinical follow up of four months after therapy, the pain level at rest had diminished by a mean of 58.3% (P < 0.0001). Pain under stress decreased by a mean of 41.9% (P < 0.0001). On MRI, 20 patients had a significant reduction of BME size or complete normalization and 4 showed no change. Worsening of the MRI pattern was found in 3 patients.
CONCLUSION
The authors conclude that the use of parenteral iloprost might be a viable method in the treatment of BME of femoral head.
