Study summary

This study is being conducted to demonstrate the safety and effectiveness of Bone Healing Accelerant (BHA) product when applied to the joint space of the ankle of hindfoot (the section of the foot immediately below the ankle joint) during fusion surgery. It is hypothesized that by 6 months, the number of subjects with successful bone fusion will be greater in the BHA-treated group compared to subjects treated with standard of care alone.

Inclusion criteria

  • Patient has pain with weight-bearing in the joint(s) below that, in the opinion of the Investigator, warrants arthrodesis:

    1. Tibiotalar (ankle)
    2. Talocalcaneal (subtalar)
    3. Talonavicular
    4. Calcaneocuboid
    5. Double hindfoot (e.g., talonavicular and talocalcaneal joints)
    6. Triple hindfoot (subtalar, talonavicular and calcaneocuboid joints
  • Joint space(s) can, in the opinion of the Investigator, be adequately filled with no more than 9 cc of graft material (BHA or ABG)
  • Each fused joint can be adequately compressed and rigidly stabilized with plates, screws, staples or a combination thereof. External fixation, percutaneous Kirschner wires or intramedullary rods may not be used.
  • Patient is willing and able to comply with all study requirements including all postoperative clinical and radiographic evaluations.
  • If patient is a woman of childbearing bearing potential (not for 12 months or surgically sterile), patient has a urine pregnancy test with a negative result at screening and on the day of surgery, prior to the procedure. These trial participants must commit to adequate through the 52-week follow-up

Exclusion criteria

Exclusion Criteria:

  • Skeletally immature patients (i.e., radiographic evidence of open physes), regardless of age
  • Bone deficit, defect or void requiring a structural graft
  • Condition requiring intramedullary nailing or external fixation for the arthrodesis
  • Condition requiring osteotomy or fusion of any midfoot joints.
  • Prior arthroplasty, arthrodesis, major surgical repair or reconstruction of the index ankle or hindfoot joints.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Successful Radiographic Fusion

    Greater than or equal to 50% bone bridging across joint space for the full complement of joints fused as determined by CT in the absence of secondary surgical or nonsurgical interventions intended to promote fusion.

    Time frame: 24 weeks
