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 (0 = unsatisfied, 10 = 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 (49,2 %) questionnaires and templates from 40 men and 25 women with an average age of 53.3 years returned. There were 40 acute and 25 chronic Mallet fingers in 35 (54 %) middle, 19 (29 %) small, 10 (15 %) ring, and 1 (2 %) index fingers. The extension deficit was classified according to Crawford.
Results:
According to the Crawford classification, there were 75 % excellent, 14 % good, and 11 % 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.
