Summary

Bioabsorbable pins offer a safe alternative to Kirschner wires for distal chevron bunionectomy fixation. This study found comparable outcomes and complication rates, with no increased risk of osteolysis or sinus formation when using bioabsorbable pins.

Area of Science:

  • Orthopedic surgery
  • Biomaterials science
  • Podiatric medicine

Background:

  • Traditional Kirschner wire fixation for distal chevron bunionectomy poses risks of infection and patient inconvenience due to protruding wires.
  • Bioabsorbable implants, while convenient, have raised concerns regarding potential osteolysis and sterile sinus formation.

Purpose of the Study:

  • To compare the outcomes and complication profiles of bioabsorbable poly-p-dioxanone pins versus stainless-steel Kirschner wires in distal chevron bunionectomy.
  • To evaluate the reliability and safety of bioabsorbable pins in osteotomy fixation for this procedure.

Main Methods:

  • A comparative study involving 114 patients (144 feet) undergoing distal chevron bunionectomy.
  • Patients were treated with either bioabsorbable poly-p-dioxanone pins or stainless-steel Kirschner wires for fixation.

  • Outcomes assessed included complication prevalence and fixation stability.

    • Main Results:

    • No significant difference was observed between the bioabsorbable pin and Kirschner wire groups regarding complication prevalence or fixation stability.
    • The prevalence of osteolysis was similar between both treatment groups.
    • No instances of sinus formation with sterile discharge were reported in the bioabsorbable pin group.

    Conclusions:

    • Bioabsorbable pins are a reliable option for osteotomy fixation in distal chevron bunionectomy.
    • Their use does not appear to carry an undue risk of osteolysis or other complications compared to Kirschner wires.
    • Bioabsorbable pins provide a convenient alternative, reducing infection risk and inconvenience associated with protruding wires.
