Main objective
Scope: Therapy
Compare the improvement in shoulder function at 3 months between the intra-articular injection group combined with a suprascapular nerve block and the intra-articular injection group combined with a placebo block.
Secondary objectives 5
- Comparison of functional outcomes between the two groups up to 12 months
- Comparison of pain progression between the two groups over a 12-month period
- Comparison of joint range of motion between the two groups up to 12 months
- Assessment of tolerance of movements
- Assessment of return to work.

- Signs or risks of infection (bacterial infection and/or fever and/or antibiotic use)
- Poor skin condition of the pathological shoulder
- - Anticoagulation with VKA or anti-Xa, or bleeding disorder currently active or in remission for less than 5 years (malignant blood disorders, myelodysplasia, autoimmune thrombocytopenia) or chemotherapy (antiplatelet agents authorized except prasugrel and clopidogrel)*

Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- The primary endpoint is the difference in Quick DASH scores between enrollment and M3.
Secondary endpoints 5
- Assessment of function using a Quick Dash score on D0, M1, M3, M6, and M12 and measurement of the area under the curve.
- Assessment of pain: VAS on D0, M1, M3, M6, and M12
- Measurement of joint range of motion with a goniometer on D0, M1, M3, M6, and M12.
- EVA pain before and after the procedure; collection of adverse events at Day 0, Month 1, Month 3, Month 6, and Month 12.
- Time to return to work after the procedure for patients who were employed at Day 0, 1 month, 3 months, 6 months, and 12 months.
