Analytic and Functional Evaluation After Surgical Treatment Using an Original Arthroscopic Trillat Technique in Patients With Chronic Anterior Shoulder Instability

• Conditions: Chronic Anterior Shoulder Instability

• Registration Number: NCT03200262
• Lead Sponsor: Centre Hospitalier Universitaire Dijon

Brief Summary

The shoulder is the most mobile joint in the body, and the most exposed to the risk of dislocation notably anterior. Chronic instability of the shoulder is frequent after dislocation, and principally affects people who are young and active. It can have major functional repercussions, leading to restricted participation in professional or sports activities, even in everyday life activities.

Surgical stabilisation is the reference treatment for chronic anterior shoulder instability, and has given good results. There are numerous surgical techniques available; the orthopaedists at Dijon CHU now practice the Bristow-Trillat technique under arthroscopy, following many years of reflexion and adaptation.

Rehabilitation following the surgery is essential, notably to recover muscle strength in the shoulder rotator cuff after surgery, which correlates directly with dynamic stability of the joint. At the moment, we do not know the objective evolution of muscle strength after the Trillat arthroscopic technique.

The isokinetic evaluation of muscle strength in the rotator cuff has been validated and is reproducible. It gives objective and reliable values for muscle strength, thus making it possible to guide and to optimise rehabilitation protocols done by patients under the supervision of a physiotherapist, and to estimate time to the return to physical, professional or sports activities, without risk.
