Abstract
Abstract
This case report evaluates the effectiveness of a patient-specific, three-dimensional titanium cage in achieving stable fixation and functional recovery for a complex distal tibial nonunion with extensive bone loss. A 45-year-old male with a severe nonunion resulting from high-energy trauma underwent implantation of a custom-designed titanium cage, created using high-resolution CT imaging to ensure precise anatomical fit. The cage, combined with a retrograde intramedullary nail and composite bone grafts, provided enhanced structural support and promoted osseointegration. Thirteen months postoperatively, the patient demonstrated minimal pain, full weight-bearing capability, and complete functional recovery. Radiographic evaluations confirmed stable fusion and effective osseointegration, restoring limb alignment and structural integrity. This case highlights the potential of customized 3D-printed titanium cages in reconstructing large bone defects in weight-bearing regions, offering a promising solution for complex fractures with severe bone loss by delivering structural stability, biocompatibility, and improved clinical outcomes.
