This video explains Bennett fracture dislocation, an oblique intra-articular fracture at the base of the first (thumb) metacarpal involving subluxation and dislocation of the metacarpal. Since the articular surface is involved, accurate reduction is essential to prevent osteoarthritis as a secondary complication. The video covers the definition, mechanism of injury, clinical features, and both closed and open reduction techniques used in its management.
