Swanson spacers can be used for DIP arthroplasty. The standard approach for Swanson spacer implantation at the DIP joint involves transecting the extensor tendon close to its insertion, which necessitates a 6-week period of postoperative immobilization. Another DIP approach involves sparing the extensor tendons, as already published. Both techniques lead to a similar range of motion of the replaced DIP joints. We present a novel approach for DIP joint arthroplasty with division of the extensor tendon in zone 2 with only 2 weeks of postoperative immobilization. Optimizing the motion-preserving operative approaches is of value to our high-demand patients. Postoperative results do not differ from the postoperative range of motion published in the literature for both tendon-sparing and standard approaches. But our approach is technically easy and requires a significantly shorter time of immobilization. Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
