Ulnar head arthroplasty has been an emerging alternative for salvage of resection arthroplasty at the distal radioulnar joint (DRUJ) since the early 1990s. Recently, it has been offered for initially treating painful arthrosis or instability of the DRUJ. This follow-up study reports a surgeon's experience treating DRUJ disorders with ulnar head arthroplasty. Twenty-two wrists in 20 patients (11 females, 9 males), 6 with no prior wrist procedures were treated between 1995 and 2006 for painful DRUJ disorders with either Herbert-Martin (Martin Medizin-Technik, Tuttingen, Germany) or Avanta (Small Bone Innovations, New York, NY) head prosthesis. Follow-up averaged 54.3 months. A standardized telephone survey determined preoperative /postoperative verbal analog pain scores and a modified Mayo Wrist Score (delineating poor, fair, good, or excellent outcomes). Data suggest that ulnar head implant arthroplasty is a reasonable treatment option for DRUJ-related pain, loss of function, or salvage of failed distal ulna resection procedures. The analog pain score statistically significant decreased by 1.68 points when comparing preoperative to postoperative scores. Average Modified Mayo Wrist Scores were good, independent of whether the procedure was primary or salvaged. No significant difference was seen between the primary or salvage group modified Mayo Wrist Scores. Whereas averaged modified Mayo scores for both the primary and salvage groups were in the good category, prostheses used as primary procedures may be associated with fewer poor or fair outcomes. Two good and 1 excellent outcome of 3 wrists requiring revision procedures suggest that even with revision of the implant arthroplasty, satisfactory results may be expected.
