Complex fractures involve severe bone damage, multiple breaks, joint involvement, or injuries accompanied by soft-tissue damage. Trauma reconstruction aims to restore bone alignment, joint stability, and full function using advanced surgical techniques such as external fixation, plating, intramedullary nailing, and bone grafting. These procedures are essential for high-impact accidents, non-healing fractures, and deformity correction. With timely treatment and proper rehabilitation, patients can regain mobility and prevent long-term complications.
