Arthroscopic Management of Intra-articular Malunion in Fractures of the Distal Radius.

Treatment of intra-articular malunion of the distal radius has evolved over the past 20 years, from open treatment to wet then dry arthroscopic techniques that provide excellent results with less morbidity than open approaches. Dry wrist arthroscopy provides a well-visualized surgical space in treating intra-articular malunion and results in less edema than wet techniques. The best results are attained in the first 3 months after injury. Alternative methods for avoiding total wrist arthrodesis in those who present later have been developed. The dry arthroscopic "inside-out" osteotomy technique for intra-articular malunions should be considered in patients with this condition.
