Ultrasonographic & MRI Explorations of Infraspinatus Muscle in

Status Recruiting

Clinical Trial Summary

The project aims to evaluate the contribution of texture analysis on MRI sections, and the technical feasibility, reproducibility, and clinical relevance of quantitative ultrasound and elastography to characterize the composition and volume of infraspinatus muscle in postero-superior rotator cuff tears. The perspectives are to optimize the imaging to allow a quantitative, objective and reproducible analysis of the muscle tissue and its characteristics.

Clinical Trial Description

The rotator cuff of the shoulder consists of 4 tendinomuscular units including the infraspinatus. This complex system fulfils a double role: stabilization/coaptation (raising the arm) and arm mobility (especially external rotation). Rupture of rotator cuff tendons is frequent (> 80% among chronic shoulder pain). They go with a decrease in muscle volume (amyotrophy) and irreversible fat infiltration. The treatment is medical and then surgical (if necessary). The degrees of atrophy and muscle infiltration (especially infraspinatus) are the criteria of choice for surgery. Actually, they are assessed in MRI according to the classification of Fuchs; it is operator dependent, qualitative and poorly reproducible with a strong inter-observer variability. Our team highlighted (2016) the possibility of using texture analysis software to objectively measure the proportion of fatty tissue on MRI sections of the cuff rotator muscles. This work also showed the possibility of using mode B ultrasound for morphological imaging and shear wave elastography to estimate the elasticity of the infraspinatus. The project aims to evaluate the contribution of texture analysis on MRI sections, and the technical feasibility, reproducibility, and clinical relevance of quantitative ultrasound and elastography to characterize the composition and volume of infraspinatus muscle in postero-superior rotator cuff tears. The perspectives are to optimize the imaging to allow a quantitative, objective and reproducible analysis of the muscle tissue and its characteristics. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

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.
