Ulnar head replacement and sigmoid notch resurfacing arthroplasty with minimum 12-month follow-up

Abstract

Our study aimed to report the short-term outcomes of patients who underwent partial ulnar head replacement and distal radial ulnar joint interposition arthroplasty. From 2012 to 2016, nine patients underwent this procedure with mean follow-up of 27 months (range 12–55). Seven of the nine patients had previously undergone surgical intervention on the ipsilateral wrist. The procedure resulted in substantial improvements in pain and function. Mayo Wrist Score improved from 37 preoperatively to 73 postoperatively, and six patients achieved a good or excellent outcome. Visual analogue pain scores decreased from 7 preoperatively to 1 postoperatively. Grip improved from 20 kg preoperatively to 30 kg postoperatively. There was no significant change in wrist range of motion. Two patients underwent revision surgery to improve wrist motion. We conclude that over short-term follow-up the procedure provides a feasible option for distal radial ulnar joint arthritis. Level of evidence: IV

Surgeon level of expertise reported in Journal of Hand Surgery (American Volume) and (European Volume) publications

“…The current review demonstrates an increase in number and percentage of reported LOE in the J Hand Surg Eur publications. Among these publications with LOE declaration in the European journal, many are American authors (Boe et al., 2018; Clark et al., 2019a, 2019b, Kazmers et al., 2019; Lovy et al., 2019; Trehan et al., 2019). It is clear that it is not American authors who have resistance or difficulty in declaration of LOE.…”
