Onderzoeksoutput: Article


Mallet fingers are injuries to the extensor tendon at the distal interphalangeal (DIP) joint and can present as a bony avulsion or as a soft tissue injury. Nonbony mallet fingers are frequently splinted in extension between 6 and 8 weeks. If splinted correctly, most results are good with a mean DIP joint extension lag between 5 and 10 degrees. However, decreased swelling, hygienic considerations and patient compliance can lead to splint removal and a less favorable outcome. We present a percutaneous tenodermodesis using only a digital block and a 4.0 nylon suture. This office-based procedure provides joint reduction and prevents joint movement during the immobilization period. The suture can be removed after 8 weeks, allowing active mobilization of the DIP joint. We present the results of 8 patients with a mean follow-up of 3 months and mean initial extension lag of 32 degrees, resulting in a mean final extension lag of 2 degrees and excellent outcomes using the Crawford criteria.
