A 3D-PRINTED LOAD SHARING IMPLANT ACHIEVED UNION OF A 9-CM FEMORAL SEGMENTAL BONE DEFECT WITHIN THREE MONTHS USING A HYBRID MASQUELET INDUCTION MEMBRANE TECHNIQUE. A CASE-REPORT.

A 3D-printed load sharing implant achieved union of a 9-cm femoral segmental bone defect within three months using a hybrid Masquelet induction membrane technique. A case-report.

Case:

A 30-year-old male was admitted in our hospital having an open left distal femoral fracture with 9-cm segmental bone defect and a closed proximal left tibial fracture. He was treated successfully using a Hybrid (Titanium Cage and Bone Graft) Masquelet Induction Membrane Technique (MIMT). His femoral fracture united 3-months post-operatively. The left tibia was treated initially with two locking plates. Following infection, a 3-cm tibial bone gap was treated with external fixation and conventional MIMT. The tibial fracture united 12-months post-operatively.

Conclusion:

The Hybrid MIMT achieved shorter time to bone union in the femur despite a much larger segmental bone defect compared to the tibial one.
