title: Distal ulna resection, extensor carpi ulnaris tenodesis, and dorsal synovectomy for the rheumatoid wrist.
abstract: We conclude from this study that distal ulna resection coupled with stabilization by ECU tenodesis is a highly useful technique with a reproducibly successful outcome for DRUJ destruction resulting from rheumatoid arthritis. In this series, like those noted previously, alleviation of pain, preservation of wrist mobility, prevention of tendon rupture, and improved function have been consistently observed. Moreover, with adjunctive dorsal synovectomy this combined procedure has proved applicable to cases demonstrating not only mild but also moderate stages of radiocarpal disease, thereby avoiding the more extensive and less desirable surgical alternatives of complete wrist arthrodesis or total wrist arthroplasty. Recognizably, the long-term benefit of this surgery depends on maintaining stability of both the reconstructed radioulnar joint and the synovectomized radiocarpal joint. Although the data reported herein strongly support the efficacy of the tenodesis in preserving distal ulna stability and similarly indicate a favorable influence on maintenance of radiocarpal architecture, one must be cognizant that progressive radiocarpal deterioration is a characteristic, albeit somewhat unpredictable, manifestation of the chronic rheumatoid process, and is the principal factor apt to compromise an initially satisfactory result. In such cases demonstrating excessive carpal malalignment preoperatively and for those with an unremitting postoperative course of ulnar translocation or volar subluxation, additional radiocarpal stabilization, preferably by arthrodesis, is essential to salvage the benefits of distal ulna resection and ECU tenodesis.
