NCT07057817

Brief Summary

The ACHILLS Trial is a multicentre randomised controlled feasibility study comparing partial calcanectomy with and without the use of an antibiotic-impregnated bone graft substitute (Cerament G) for treating calcaneal osteomyelitis, specifically on wound healing rates, re-infection, and overall efficacy in a sample of 30 patients over a one-year period.

Outcome Measures

Primary Outcomes (4)

  • Rate of Wound Healing

    To determine the number of patients achieving complete wound healing in patients undergoing treatment with cerament G compared to those with partial calcanectomy alone by measuring wound volume

    1 months post-surgery

  • Rate of Wound Healing

    To determine the number of patients achieving complete wound healing in patients undergoing treatment with cerament G compared to those with partial calcanectomy alone by measuring wound volume

    3 months post-surgery

  • Rate of Wound Healing

    To determine the number of patients achieving complete wound healing in patients undergoing treatment with cerament G compared to those with partial calcanectomy alone by measuring wound volume

    6 months post-surgery

  • Rate of Wound Healing

    To determine the number of patients achieving complete wound healing in patients undergoing treatment with cerament G compared to those with partial calcanectomy alone by measuring wound volume
