Twenty-five patients underwent PIPJ fusions with OSSIOfiber Hammertoe Fixation Implants. Primary performance endpoints were radiographic PIP joint fusions and secondary endpoints included patient-reported outcome measures with follow-up at 2, 4, 6, 12, and 26 weeks postoperatively, as well as overall patient satisfaction scores. A second, longer term study is anticipated publication in 2021. 


Key Findings:

  • All operated joints (100%) were evaluated as clinically stable, with excellent bony fusion rate (88%) at 26 weeks, which is of the highest published fusion rates for hammertoe fixation solutions.
    • Absorbable intramedullary implants - Averaged 82%
    • Allograft implants - Averaged 77%
    • Nitinol implants – Averaged 79%

    • Metal Implants – Averaged 74%

    • K-Wire fixation – Averaged 61%

  • No complications or serious adverse events, no withdrawals from the study 
  • Substantial patient-reported improvements in pain and function 
  • 100% of patients matched or exceeded their expectations for postoperative results and were likely to choose this implant again
