Pivot osteotomy for the correction of malunion of metacarpal neck fractures.

A new configuration of osteotomy has been developed which combines the principles and benefits of opening and closing wedge osteotomies without the degree of shortening associated with the closing wedge osteotomy and the tension imposed on the soft tissues by the opening wedge osteotomy. It is ideally suited to the correction of angular malunions in the long bones of the hands. Ten osteotomies of malunions of the metacarpals have been performed in nine hands giving good correction of the malunion in all cases.
