• OBJECTIVES
    • To evaluate the clinical efficacy and safety of a novel surgical technique combining K-wire fixation with pull-out wire fixation for treating acute bony mallet finger.
  • METHODS
    • This retrospective study included 23 patients with acute bony mallet finger treated between January 2023 and December 2024. Inclusion criteria were injuries within 4 weeks, failed conservative treatment, and fracture fragment size greater than one-third of the articular surface. Surgical details included stabilizing the DIP joint with a K-wire and supplementary fixation with pull-out steel wires to enhance stability. Postoperative outcomes were assessed using the Visual Analog Scale (VAS) score, range of motion (ROM), and Crawford criteria. Data were analyzed using SPSS software.
  • RESULTS
    • The mean age of patients was 33.78 ± 10.49 years. All 23 patients experienced no complications. The mean postoperative ROM of the affected DIP joint (75.09 ± 5.32°) was comparable to the healthy side (76.83 ± 5.91°). VAS scores indicated no pain, and Crawford criteria showed excellent or good outcomes in all cases.
  • CONCLUSIONS
    • The combined K-wire and pull-out wire technique appears to be a safe and effective option for treating acute bony mallet finger, offering stable fixation and good early functional outcomes.
