Group Intervention Description HBS 2 Resorb Mg Treatment with HBS 2 Resorb Mg Study arm treated with the HBS 2 Resorb Mg.
- Primary Outcome Measures
Name Time Method Bony Fusion (Change) 6 weeks, 12 weeks, 6 month and 12 month after surgery 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.
- Secondary Outcome Measures
Name Time Method Surgical revisions(YES/NO) 6 weeks, 12 weeks, 6 month and 12 month after surgery 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.
Secondary displacement and breakage of the implant (YES/NO) 6 weeks, 12 weeks, 6 month and 12 month after surgery Any secondary radiographic displacement or breakage of the implant or any clinically significant loss of reduction is noted.
Clinical outcome 6 weeks, 12 weeks, 6 month and 12 month after surgery Patient pain (VAS) and outcome measures (Patient Related Outcome Measure) will be noted in order to assess patient satisfaction.
Early corrosion phenomenon(YES/NO) 6 weeks, 12 weeks, 6 month and 12 month after surgery Symptomatic gas accumulation or formation of gas pockets due to degradation of the material.
Deep infection(YES/NO) 6 weeks, 12 weeks, 6 month and 12 month after surgery The presence of deep infections is assessed binary.
Radiolucency(YES/NO) 6 weeks, 12 weeks, 6 month and 12 month after surgery Any radiolucency on the postoperative X-rays are noted. Radiolucency will be assessed by the operating surgeon.
