Abstract

For two decades, scaphoid nonunion has been treated arthroscopically. However, compressed cancellous bone graft does not have the same mechanical properties as corticocancellous bone graft for reducing the scaphoid humpback deformity and DISI tilt. Here, we describe an arthroscopic technique to treat Alnot stage IIB scaphoid nonunion. We treated a 27-year-old male patient for scaphoid waist nonunion with humpback deformity and DISI. A 8×8×10 mm cylindrical corticocancellous bone graft was harvested from the dorsal aspect of the radius using a single-use osteochondral autograft transfer system (OATS®, Arthrex Inc., Naples, USA). It was inserted in the nonunion site through an arthroscopic volar approach. Bone union was obtained at 3 months with lasting correction of the scaphoid humpback deformity and DISI. The functional result at 6 months was excellent. There were no complications. Scaphoid nonunion with humpback deformity and DISI may be treated arthroscopically with a corticocancellous bone graft.
