Abstract:
Purpose:We aimed to determine whether the clinical outcomes of antegrade and retrograde extra-articular Kirschner wire (K-wire) pinning differed in proximal phalanx base fractures.
Methods:This retrospective study investigated 73 patients aged ≥18 years with extra-articular proximal phalanx base fractures that were treated by closed K-wire pinning between January 2014 and June 2023. Patients were analyzed according to whether the K-wire fixation was antegrade or retrograde. We analyzed demographics, injury characteristics, the number of K-wires applied, surgical duration, the interval before implant removal, and when physical therapy was started. Radiological outcomes included the amount of time required for radiographically confirmed bone union. Clinical outcomes consisted of complications, total active motion (TAM), and the Michigan Hand Outcomes Questionnaire (MHQ).
Results:We treated 29 and 44 patients using antegrade and retrograde K-wire fixation, respectively. The overall complication rate was higher in the antegrade group than in the retrograde group (13.8% vs. 9.1%), although this difference was not statistically significant. Similarly, no significant between-group differences were detected in the length of time required for bone union and implant removal, TAM, and MHQ scores.
Conclusion:Proximal phalanx base fractures were equally and effectively treated by antegrade and retrograde K-wire fixation. Therefore, the direction of K-wire fixation can be chosen based on surgeons’ preferences and experience.
