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.
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.

RECRUITINGConstant Murley Score (CMS)
The primary performance endpoint is the change in the CMS from baseline to 1 year after surgery. Minimum score is 0 maximum is 100 with the better functioning shoulders having a greater number of points.
Time frame: 1 year
Device Related or Procedure Related Adverse events
device-related and/or procedure-related adverse events up to 1 year after surgery.
Time frame: 1 year
Constant Murley Score (CMS)
Change from baseline CMS and subscale scores (pain, activities of daily living, strength and ROM) at each timepoint up to 3 years after surgery. Minimum score is 0 maximum is 100 with the better functioning shoulders having a greater number of points.
Time frame: 3 years
American Shoulder and Elbow Surgeons Score (ASES)
Change from baseline American Shoulder and Elbow Surgeons (ASES) Score at each timepoint up to 3 years after surgery. Total score 0-100 ASES points, 0 = worse pain and functional loss/disability.
Time frame: 3 years
RAND Short Form 36 (SF-36) V1
Change from baseline RAND Short Form 36 (SF-36) V1 Quality of Life Health Survey at each timepoint up to 3 years after surgery.The RAND SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section. Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability.
Time frame: 3 years
Nottingham Clavicle Score (NCS)
Change from baseline Nottingham Clavicle Score (NCS) at each timepoint up to 3 years after surgery. Maximum score of 100 (fewest difficulties) and a minimum score of 20 (most difficulties)

The scale is a line which will be marked by the subject, it will be reported as 0-100% with 100% meaning they are able to perform 100% of their normal daily work or recreational activity
Time frame: 3 years
coracoclavicular distance
Change from baseline CC distance using the anteroposterior (AP) X-ray (Zanca view) at each timepoint up to 1 year after surgery.
Time frame: 1 year
Device-related and/or procedure-related adverse events
Device-related and/or procedure-related adverse events up to 3 years after surgery.
