Interphalangeal joint salvage arthrodesis using the lister tubercle as bone graft.

Abstract

Treating failed interphalangeal joint arthroplasty is challenging. After an implant or surgical device has been removed, minimal cortical bone remains, and cancellous bone is largely absent from the medullary canals. Several surgical techniques exist for athrodesis of these joints, which render the operated digit unnaturally straight and shortened. Using the Lister tubercle as a graft provides the unique benefits of maintaining the natural length of the joint while also lending a natural curvature to the finger.
