New shoulder button system tested for Long-Term safety
NCT ID NCT05397210
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 58 people who have a dislocated shoulder joint (acromioclavicular joint) to see how well a medical device called the Infinity-Lock Button System works over time. The device is used to stabilise the joint after injury. Researchers will measure shoulder function and any side effects for up to 3 years after surgery.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patient must be 16 years old or above. * Patient is diagnosed with acute or chronic Grade Ill-VI ACJ dislocation. * Patient is willing to participate in the study and have been informed of the nature of the study, agree to its follow-up and have provided written informed consent as approved by the Research Ethics Committee (REC). Exclusion criteria. * Known hypersensitivity to implant materials. If the patient is suspected of having any foreign body sensitivity, appropriate tests should be made prior to implantation. * Infections or any other structural or pathological condition of the bone or soft tissue (such as hyperlaxity) that would be expected to impair healing or secure fixation. * Patients unable or unwilling to restrict activities to prescribed levels or follow a rehabilitation programme during the healing period. * Skeletally immature patients are not suited as the Infinity-Lock™ Button System will not elongate with growth. The use of this medical device and placement of hardware or implants must not bridge, disturb or disrupt the growth plate. * Any other conditions or factors which in the opinion of the Investigator may interfere with study conduct.
