Primary Outcome Measures:
  • Constant Score [ Time Frame: change from Baseline in Constant Score at 24 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Disabilities of Arm, Shoulder and Hand function (QuickDASH) [ Time Frame: change from Baseline in QuickDASH at 24 months ] [ Designated as safety issue: No ]

Other Outcome Measures:
  • Shoulder Pain and Disability Index (SPADI) [ Time Frame: Change from baseline in SPADI at 24 months ] [ Designated as safety issue: No ]
  • Radiographs with and without weight [ Time Frame: Change in the position of the AC-joint from baseline to at 24 months ] [ Designated as safety issue: No ]
    Position of the AC-joint will be measured at standard radiographs and weighted radiographs

  • European Quality of Life - 5 dimensions (EQ5D) [ Time Frame: Change from baseline in EQ-5D at 24 months ] [ Designated as safety issue: No ]
  • Pain rated with Visual Analogue Scale (VAS) [ Time Frame: Change from baseline in VAS at 24 months ] [ Designated as safety issue: No ]
  • Computed Tomography [ Time Frame: Change in the position of the AC-joint from baseline to at 24 months ] [ Designated as safety issue: No ]
    Position of the AC-joint
