The purpose of this study is to report the percentage of patients achieving union, time to union, and complications with the use of bone morphogenetic protein-2 (rh-BMP-2) in surgical repair of established nonunion in the hand and wrist. Twenty-seven patients with nonunion of the hand and wrist were treated between 2005 and 2011 with surgical repair and augmentation using 4.2 mg of rh-BMP-2. Sites of nonunion included the phalanx (seven), carpus (nine), distal radius (five), and distal ulna (six). Radiographic union and complications were the primary and secondary outcomes, respectively. Eightynine percent (24/27) of patients achieved union within an average of 4.3 š 2.8 months of surgery. There were no direct complications from administration of rh-BMP-2. Radiographic union was consistent with published rates for nonunion repair of scaphoid, phalanx, and distal radius fractures. Rh-BMP-2 did not produce superior rates of union in the patients with wrist and hand nonunion.
