结局指标

主要结局

Union Rates

时间窗: 12 months

Radiographic evidence of successful arthrodesis confirmed on Computed Tomography (CT) scan defined by \>50%. Results are for total number of joints fused which exceeds the number of participants due to some subjects having multiple joints fused.

  • Foot and Ankle Ability Measure (FAAM) - Activities of Daily Living (ADL) Subscale(baseline, 3 month, 6 month, 1 year)
  • Vitamin D Levels(baseline, 6 months)
