Introduction: There is a wide variety of therapeutic options for the reconstruction of segmental bone defects caused by fractures, tumors, or infections, but it continues to be a challenge in orthopedic surgery. Materials and Methods: The present work presents six (6) cases of patients with massive bone loss treated by means of what we call a “synergistic combination” of an induced membrane, to provide biological benefits, plus a trabecular titanium scaffold designed for each patient to provide stability and structure. Results: Five men and one woman with an average age of 30 years were operated on by this technique. The average follow-up was 24 months. In the immediate postoperative period, the axis, length, and sufficient mechanical stability to initiate partial weight-bearing were reestablished. Full weight-bearing according to the patients’ conditions (pain, muscle strength) required an average of 25 to 30 days. Conclusion: We propose a rare treatment option in our field with sufficient biomechanical stability to tolerate early weight-bearing, recovering the entire length of the defect in a single stage with excellent functional outcomes, understanding these as an advantage over traditional therapeutic options such as bone transport or the Masquelet technique.
