A minimum of 44 patients undergoing Medial or Lateral Displacement Calcaneal Osteotomy (MDCO) will be randomized in two parallel groups for surgery, considering applied the implant. One group will be operated using two 4.0mm cannulated bio-integrative (absorbable) screws, and the other group using two 4.0mm cannulated metallic screws. Patients will be blinded evaluated for a mean follow-up of twelve weeks in terms of bone healing, complications, and implant-related artifact using weight-bearing computed tomography (WBCT).
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.
