Arthroscopic Management of Scaphoid Nonunion.

Arthroscopic bone grafting (ABG) in difficult scaphoid delayed union and nonunion allows thorough assessment and comprehensive management for scaphoid fracture and its sequelae. It provides a favorable biological environment for bony healing and produces minimal trauma to the soft tissues, aiding in rehabilitation. With adequate training and experience, high union rates and satisfactory clinical outcomes can be achieved. Poor blood supply of the scaphoid is not a contraindication to bone grafting; union rates over 80% have been reported, comparable to other existing surgical methods. This article discusses the rationale, surgical techniques, and results of ABG.
