Retrospective study of closing wedge osteotomy complications at the base of the first metatarsal with bone screw fixation.

The authors describe the surgical technique for bone screw fixation of closing wedge osteotomies of the first metatarsal. They found that the angle of the bone screw should be perpendicular or almost perpendicular to the osteotomy or fracture. They also found age and time of weightbearing to be important factors.
