Salvage of Failed Resection Arthroplasties of the Distal Radioulnar Joint Using an Ulnar Head Prosthesis: Long-term Results
چکیده انگلیسی

PurposeThe aim of this prospective multicenter study was to evaluate the long-term outcome of the Herbert ulnar head prosthesis for painful instability of the distal radioulnar joint (DRUJ) following resection of the ulnar head.MethodsTwenty-three patients were treated with a Herbert ulnar head prosthesis in 3 international hand centers. One patient was excluded from the study because a septic prosthesis had to be removed after 3 months. Sixteen of the remaining 22 patients could be assessed at 2 follow-up times, 28 months (range, 10–43 mo) and 11 years and 2 months (range, 97–158 mo) after surgery, for DRUJ stability, forearm rotation, grip strength, pain level (0–10), and satisfaction (0–10). Standardized radiographs of the wrist were evaluated for displacement of the ulnar head and loosening or bony reactions at the sigmoid notch or the ulna shaft.ResultsAll patients demonstrated a clinically stable DRUJ at the latest examination, and no patient required further surgery at the DRUJ since the short-term evaluation in 1999. Average pain measured 3.7 before surgery, 1.7 at the short-term follow-up, and 1.7 at the long-term follow-up; patients' satisfaction, 2.2, 8.2, and 8.9; pronation, 73°, 86°, and 83°; supination, 52°, 77°, and 81°; and grip strength, 42%, 72%, and 81% of the unaffected side. All clinical parameters improved significantly from before surgery to the short-term follow-up, with no further statistically significant change between the short-term and long-term follow-up. Radiographs demonstrated no signs of stem loosening or incongruity of the DRUJ.ConclusionsThe previously reported short-term results with the Herbert prosthesis did not deteriorate in the long term. Reconstruction of the DRUJ with this prosthesis in painful radioulnar impingement following ulnar head resection is a reliable and reproducible procedure with lasting results.Type of study/level of evidenceTherapeutic IV.
