Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Post-market Clinical Follow-up Study. It will verify the long-term safety and performance of the Infinity-Lock Button System (ILBS) when used for acute and chronic dislocations of the Acromioclavicular Joint and used as described by the manufacturer's instructions.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Post-market Clinical Follow-up Study. It will verify the long-term safety and performance of the Infinity-Lock Button System (ILBS) when used for acute and chronic dislocations of the Acromioclavicular Joint and used as described by the manufacturer's instructions.

The medical device (ILBS) in this study is already on the market and is manufactured by Xiros Ltd.

The ILBS comprises of a polyester flexible tubular tape and a titanium button. The tape is used to secure the joint and the button is used to secure the tape into position.

This study will collect data on patients who meet the entry criteria and receive the device; it will recruit patients from several clinical sites.

All patients in the study will receive the ILBS, as it is a single armed study. The total length of the study is expected to be 4.5 years; this includes a recruitment period of approximately 18 months and a 3-year follow-up.

A total of 58 subjects will be enrolled into the study. Follow up is at 3 months, 6 months, 1,2 and 3 years.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.
