RESUMO
INTRODUCTION: Mallet fingers are the most common tendon injuries of the hand. Bony avulsion distal finger extensor tendon ruptures causing a mallet finger require special attention and management. In this monocentral study, we analyzed the clinical and individual outcomes succeeding minimal invasive k-wire extension block treatment of bony mallet fingers. MATERIALS AND METHODS: In a retrospective study, we sent a self-designed template and a QUICK-DASH score questionnaire to all patients, who were treated because of a bony mallet finger between 2009 and 2022 and fulfilled the inclusion criteria. A total of 244 requests were sent out. 72 (29.5%) patients participated in the study. Forty-five men and twenty-seven women were included. RESULTS: 98.7% (n = 75) of the cases were successfully treated. Patients were highly satisfied with the treatment (median 8.0; SD ± 2.9; range 1.0-10.0). Based on the QUICK-DASH score, all patients showed no difficulties in daily life. The extent of avulsion did not influence the outcome. CONCLUSION: We conclude that the minimally invasive treatment of a bony mallet finger should be offered to every patient, because it is safe, fast, and reliable. Thus, we propose to perform extension-block pinning independently of the articular area.

PURPOSE: This retrospective, unicenter cohort study analyse the clinical and subjective results following temporarily K-wire transfixation of the distal interphalangeal joint (DIPJ) in hyperextension in Mallet fingers. PATIENTS AND METHODS: By means of a self-designed questionnaire demographic data, patient´s satisfaction (0â =â unsatisfied, 10â =â very satisfied), persisting pain (yes/no), postoperative complications, and the Quick-DASH score were evaluated. In addition, range of motion of the DIPJ was measured with use of a self-designed template for self-evaluation by the patients. Questionnaire and template were send to 132 patients in whom a Mallet finger was treated between January 2009 and December 2019 with K-wire transfixation of the DIPJ. 65 (49,2â %) questionnaires and templates from 40 men and 25 women with an average age of 53.3â years returned. There were 40 acute and 25 chronic Mallet fingers in 35 (54â %) middle, 19 (29â %) small, 10 (15â %) ring, and 1 (2â %) index fingers. The extension deficit was classified according to Crawford. RESULTS: According to the Crawford classification, there were 75â % excellent, 14â % good, and 11â % satisfied results. With an average of 7,9 points the patients were very satisfied. 15 patients reported about complications with six complaining persisting pain. The Quick-DASH score averaged 5.4 points. CONCLUSION: The treatment of Mallet fingers by transfixation of the DIPJ using a K-wire is an appropriate method leading to a good.
