In the article by Orbay et al in the September 2021 issue of The Journal of Hand Surgery (“Effect of Ulnar Head Offset on Distal Radioulnar Joint Stability”, Vol. 46, No. 9, p. 816.e1-816.e7), the last author Deana Mercer, MD, did not make an accurate conflict of interest disclosure. The complete disclosure (update in bold) should have read: “J. Orbay is a consultant for Skeletal Dynamics Inc. D. Mercer is an educational consultant for Skeletal Dynamics Inc. The rest of the authors declare that no benefits in any form have been received or will be received related directly or indirectly to the subject of this article.” The authors regret this error.

- Effect of Ulnar Head Offset on Distal Radioulnar Joint StabilityJournal of Hand SurgeryVol. 46Issue 9
- PreviewA complete ulnar head replacement may be indicated in cases of distal radial ulnar joint (DRUJ) dysfunction to address bony pathology in lieu of using a constrained total DRUJ prosthesis. Complete ulnar head implants are simple, but they may be unstable if soft tissue tension is not adequately restored. We hypothesized that incorporating an increased offset in the complete ulnar head replacement would lead to increased tension on the distal oblique interosseous ligament, increased contact force at the DRUJ, and improved joint stability.
