Brief Summary:
This is a single arm pilot study in patients requiring surgical fusion in the foot or ankle. Patients will receive map3® Cellular Allogeneic Bone Graft containing donor matched stem cells. This cohort study will enroll 24 patients total at 1 site. After subjects have signed an informed consent, the baseline visit and examinations will be completed. Patients will be evaluated at 2 weeks, 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery.

Detailed Description:
map3® Cellular Allogeneic Bone Graft provides the desired osteoconductive, osteoinductive and osteogenic potential capacities which are essential to optimal fracture healing when bone grafts are implanted. It offers viable MAPC-class cells on a scaffold comprised of demineralize bone matrix (DBM) and cortical cancellous chips. map3® Cellular Allogeneic Bone Graft is considered an allograft, and as such, is indicated for bone repair for orthopaedic indications where autograft is employed. The primary goal of this study is to evaluate the outcomes in bone grafts of the foot or ankle using a stem cell modified allograft (map3® Cellular Allogeneic Bone Graft). The study endpoints will be objectively determined via x-rays and CT scan to assess bony fusion, extremity evaluation using the AFAS and subjective patient scores for foot disabilities and quality of life.

Arm Intervention/treatment
map3 allogeneic bone graft
Patients will receive map3® Cellular Allogeneic Bone Graft containing donor matched stem cells.
Device: map3
Patients will receive map3® Cellular Allogeneic Bone Graft containing donor matched stem cells.

Primary Outcome Measures :
  1. AOFAS Foot-and-Ankle Score [ Time Frame: 24 months ]
    The American Orthopaedic Foot and Ankle Society score returns an indexed score, from 0 - 100, to assess clinical outcomes following foot /ankle surgery.

Secondary Outcome Measures :
  1. SF-36 Score [ Time Frame: 24 months ]
    The SF-36 is a survey for health and well-being.

  2. Foot Ankle Disability Index [ Time Frame: 24 months ]
    The Foot Ankle Disability Index (FADI) is a self-report of function that assesses activities of daily living, with scores ranging from 0 to 100.

  3. CT Scan [ Time Frame: 6 months ]
    A CT scan will be done at 6 months in order to assess bone fusion.

Other Outcome Measures:
  1. Time to Full Weight-bearing [ Time Frame: up to 24 months ]
    This will be the time from the date of surgery until the patient has full, unassisted weight bearing, and will be measured in weeks.
