Treatment of radiocarpal degenerative osteoarthritis by radioscapholunate arthrodesis: long-term follow-up

Abstract

Radioscapholunate arthrodesis is the treatment of choice for symptomatic, degenerative radioscapholunate osteoarthritis. We report on three patients after radioscapholunate arthrodesis with a follow-up of 22-28 years. There were no short-term postoperative complications; range of motion and strength were stable. All three patients showed radiological evidence of progressive, but clinically asymptomatic midcarpal osteoarthritis. The conversion rate for radioscapholunate to panarthrodesis of the wrist is reported at 31% with follow-ups of more than five years, invariably due to either non-union, or progressive, symptomatic midcarpal osteoarthritis. Primary excision of the distal pole of the scaphoid during radioscapholunate arthrodesis probably plays an important role in avoiding these conditions in the long-term. This measure allows a residual range of motion more than previously believed; considering that the dart thrower's motion is the physiological axis of wrist motion.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
