Fractures at the base of the thumb: treatment with oblique traction

Oblique traction on the thumb metacarpal, originally described for the treatment of Bennett's fracture, has been applied to comminuted intra-articular fractures of the thumb metacarpal to counter the forces that cause shortening and varus angulation. It also has been applied to fractures of the trapezium to restore congruity of the trapeziometacarpal joint. It was successful in achieving and maintaining a satisfactory reduction in eight patients with these three types of fractures.
