Brief Summary

The use of bio-integrative implants in orthopedic surgery is growing exponentially. As many biomechanical and histological studies were able to sustain its structural and biological properties, few clinical studies are available to support its advantages, such as good osteosynthesis, lower rates of removal, and diminished implant-related artifact in imaging studies. This information is vital to providers when choosing the proper material and planning postoperative treatment. This trial intends to test the capacity of the bioabsorbable screws in reaching the same clinical and radiographical outcomes of the current metallic screws.

Outcome Measures

Primary Outcomes (1)

  • Bone healing

    \- Amount of bone bridging crossing the osteotomy site: Determined by the percentage of bone trabeculae crossing the osteotomy site on every tomography cut (amount of the cut in millimeters that shows bone spanning the two fragments divided by the total amount of osteotomy's surface on the cut). \- Weight-bearing computed tomography (WBCT) acquisitions will be used to determine this percentage.

Secondary Outcomes (2)

  • Complications

    6 weeks

  • Implant-related artifact

Study Arms (2)

Bio-integrative

EXPERIMENTAL

Traditional oblique calcaneus osteotomy through a lateral approach. After a 10mm displacement, the osteotomy will be fixed with two 4.0mm bio-integrative cannulated screws.

Procedure: Calcaneus Osteotomy (Bio-integrative)

Metallic

ACTIVE COMPARATOR

Traditional oblique calcaneus osteotomy through a lateral approach. After a 10mm displacement, the osteotomy will be fixed with two 4.0mm metallic cannulated screws.

Procedure: Calcaneus Osteotomy (Metallic)

Eligibility Criteria

Age18 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Individuals must be older than 18 and younger than 75 years of age, both genders;
  • Participants must be experiencing symptoms related to their baseline condition for at least six months before the surgery;
  • Clinical diagnosis of hindfoot malignment, defined as the presence of a clinical hindfoot angle above 10 degrees of valgus or any degree of varus;
  • Surgical planning, including a calcaneus displacement osteotomy through a traditional oblique cut.

You may not qualify if:

  • Previous surgery involving the affected calcaneus;
  • History or documented evidence of autoimmune or peripheral vascular diseases;
  • History or documented evidence of peripheral neuropathy (nervous compression syndrome, tarsal tunnel syndrome) or systemic inflammatory disease a (rheumatoid arthritis, spondylitis, Reiter Syndrome, etc.);
  • Any condition that represents a contraindication of the proposed therapies;
  • Impossibility or incapacity to sign the informed Consent Form;
  • Presence of infectious process (superficial on the skin and cellular tissue, or deep in the bone) in the region to be treated.
  • Osteotomies requiring resection of wedges (Dweyer, triple Dweyer, etc.);
  • Osteotomies planned to occur in a non-traditional cut (Malerba, Scarf, etc.).
