Acromioclavicular pains are one of the etiologies of shoulder pains, the prevalence of which is relatively high, ranging from 5 to 47% in the general population. The cause is usually degenerative, occurring mainly after the age of 40, especially in male manual workers. This pathology is described as the great forger of the shoulder, ignored by clinicians because it is often uninvestigated, whereas an interrogation and a complete clinical examination are sufficient to make the diagnosis.

Acromioclavicular pathologies are better known to orthopaedic surgeons, particularly in traumatic pathologies but also in degenerative pathologies. However, before operating on acromioclavicular osteoarthritis, interventions whose results are sometimes disappointing, a well-managed medical treatment usually helps to relieve pain.

The precise clinical examination and a radiological examination focused on the joint make it possible to diagnose acromioclavicular arthropathy, the key is to think about it and look for it.

Care includes explanation of the diagnosis, drug treatments, physiotherapy techniques and self-exercise as well as osteoarticular manipulations, which are less frequently practiced or performed in isolation outside the medical setting.

The results of the different treatments have been little studied, with studies that don't always allow us to distinguish several etiologies of shoulder pains. Most studies compare surgical techniques with each or with medical techniques. However, there are very few studies comparing traditional medical care with manual medicine.

In order to compare the different non-surgical therapies for the care of acromioclavicular arthropathies of degenerative origin, the investigators propose a dedicated study.

This is a non-inferiority, prospective, open, randomized, two-armed study comparing the efficacy of manipulations by a physician with a training in manual medicine versus cortisone infiltration Under ultrasound control.

After diagnosis of degenerative pathology of the acromioclavicular joint, patients meeting the inclusion criteria will be randomized to the infiltration arm or to the manipulations arm.

The assessment will be based on the pain during and after the procedure.
