Update on the operative treatment of scapholunate instability for radiologists. II. Salvage procedures, total wrist arthrodesis, and total wrist arthroplasty

Skeletal Radiol. 2017 Aug;46(8):1031-1040. doi: 10.1007/s00256-017-2671-0. Epub 2017 May 26.

Abstract

Scapholunate (SL) instability is the most common form of carpal instability. Imaging (especially radiography) plays an important role in the staging, management, and postoperative follow-up of SL instability. In the final stage of SL instability, known as scapholunate advanced collapse, progressive degenerative changes occur at the carpal level. The goals of this article are to review the surgical options available for addressing the different stages of scapholunate advanced collapse, along with an emphasis on normal postoperative imaging and complications associated with each surgical option.

Keywords: Four-corner fusion; Proximal row carpectomy; Scapholunate instability; Total wrist arthrodesis; Total wrist arthroplasty.
