Late complications in elbow arthroplasty.
The world literature (1986 to 92) reports an amazingly high complication rate of elbow arthroplasty, amounting to 43%. Accordingly, we also find a high revision rate (18% on average) and a considerable rate (15%) of permanent complications. These figures do not correspond to our own experience with the GSB III (Gschwend/Scheier/Bähler) elbow prosthesis, a sloppy hinge with flanges on the lower and anterior part of the distal humerus. Our respective figures of complications are two to four times lower for rheumatoid elbows. When complications are discussed, a clear distinction of the type of prosthesis is mandatory, because linked or nonlinked and nonconstrained or semiconstrained prostheses have specific complications. The following complications are discussed separately: loosening (radiologic and clinical), ulnar neuropathy, infection, dislocation and subluxation, uncoupling, intraoperative bone fractures, and failure of the implant. The possible causes are analyzed, and means to avoid or treat these complications are discussed. We conclude that even in the long term ( > 10 years), results obtained with elbow arthroplasty are approaching those of hip and knee arthroplasty.
