Congenital Medial Deviation clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Three-Dimensional Hindfoot Alignment Measurements Based On Biplanar Radiographs: Prospective Clinical Feasibility Study

Start date: July 2014
Phase:
Study type: Observational

- The measurement of hindfoot alignment is a technical challenge. - Today, hindfoot alignment is typically measured on hindfoot alignment view radiographs or long axial view radiographs. Measurements on both types of radiographs are hampered by technical shortcomings such as minimal rotational misplacement of the foot at the time of image acquisition. In previous publications our study groups demonstrated substantial measurement errors due to these shortcomings as well as bad interreader agreement. - Hindfoot alignment measurement is feasible on MR images but hampered by the non-weight-bearing position of the patient and therefore not suited for pre-treatment evaluation. - In an ex vivo study using plastic phantoms of a foot our research group could demonstrate superior interreader agreement and complete correction for foot misplacement at the time of image acquisition using a 3D secondary measurement technique based on biplanar low dose radiographs. - Image acquisition using biplanar low dose radiographs is associated with a substantial reduction (about 1/7) of radiation dose applied to the patient compared to standard radiographs. - Therefore the question arises if these excellent ex vivo results can be confirmed in a prospective clinical study. Objectives: 1. Evaluation of technical feasibility of 3D hindfoot alignment measurements based on biplanar radiographs. 2. Reproduction of superior interreader agreement of measurements based on biplanar radiographs compared to measurements on conventional radiographs.
