E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary aim is to test the reduction of bone marrow edema syndrome after a singular intravenous treatment with Zoledronic Acid within 6 weeks compared to placebo. The volume of the edema is defined as biometric data measured by the use of MRT before and six weeks after treatment. The hypothesis has to be checked whether Zoledronic Acid is efficient in the treatment of painfull bone marrow edema. A statistically significant reduction of the edema in the MRT is considered as evidence for efficacy. |
|
E.2.2 | Secondary objectives of the trial |
Secondary objectives are to assess safety and tolerance of the study medication compared to placebo as well as changes in the following parameters:
Reduction of pain (VAS)
Quality of life (Qualeffo-41 questionnaire)
Subjective estimation of medical condition (PDI)
Number of additional medicinal visits
Number of days of illness
Descriptive analysis of side effects and changes of the parameter concerning the osteologic values
Number of aseptic bone necrosis and fatigue fractures |
