Outcome Measures

Primary Outcomes (8)

  • incidence of surgical revisions

    Was a surgical revision done postoperatively? YES/NO

    1 year

  • incidence of loosening of the screw

    based on x-rays: Is a loosening of the screw visible? YES/NO

    1 year

  • incidence of cracking of the screw

    based on x-rays: Is a cracking of the screw visible? YES/NO

    1 year

  • Hallux valgus angle

    based on x-rays: What ist he Hallux valgus angle? °

    1 year

  • Intermetatarsal angle

    based on x-rays: What is the intermetatarsal angle? °

    1 year

  • incidence of postoperative pseudoarthrosis

    based on x-rays or MRI: Is a postoperative pseudoarthrosis visible? YES/NO

    1 year

Secondary Outcomes (2)

  • Patient satisfaction (VAS)

    1 year

  • Assessment according to the AOFAS score

    1 year
