Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Bony Fusion (Change)	The primary endpoint of the study is the fusion rate of the bone. After the onset of bony fusion, the implant no longer fulfils any function, and it should be resorbed.	6 weeks, 12 weeks, 6 month and 12 month after surgery
Secondary	Secondary displacement and breakage of the implant (YES/NO)	Any secondary radiographic displacement or breakage of the implant or any clinically significant loss of reduction is noted.	6 weeks, 12 weeks, 6 month and 12 month after surgery
Secondary	Deep infection(YES/NO)	The presence of deep infections is assessed binary.	6 weeks, 12 weeks, 6 month and 12 month after surgery
Secondary	Clinical outcome	Patient pain (VAS) and outcome measures (Patient Related Outcome Measure) will be noted in order to assess patient satisfaction.	6 weeks, 12 weeks, 6 month and 12 month after surgery
Secondary	Surgical revisions(YES/NO)	As typically one single surgery should be sufficient to treat the patient, all secondary surgical interventions are revisions due to a complication. This includes also re-operation due to screw removal.	6 weeks, 12 weeks, 6 month and 12 month after surgery
Secondary	Early corrosion phenomenon(YES/NO)	Symptomatic gas accumulation or formation of gas pockets due to degradation of the material.	6 weeks, 12 weeks, 6 month and 12 month after surgery
Secondary	Radiolucency(YES/NO)	Any radiolucency on the postoperative X-rays are noted. Radiolucency will be assessed by the operating surgeon.	6 weeks, 12 weeks, 6 month and 12 month after surgery
