Delta wiring has become a widespread
technique for the treatment of bony mallet fracture. This
technique enables fragment compression and immediate
DIP joint active movement. The Delta wiring has become
an alternative for the extension bock technique. We intend
to describe the technique and results of Delta wiring for
the surgical treatment of bony mallet injury. The aim of
this study was to describe the Delta wire and provide a
clinical and radio- logical evidence in the treatment of
mallet fractures. The hypothesis of this study was that
Delta wiring technique would obtain similar clinical and
functional results to those of traditional extension block in
the surgical treatment of mallet fractures, and that Delta
wire could be a safe, viable treatment choice as an
alternative to Extension block technique.
Eighteen patients submitted to Delta wiring for the
treatment of mallet fracture were included and assessed
in this study, during the period of January 2017 to May
2020 with a complete assessment in minimum follow-up of
6months. The technique was indicated for patients with
acute mallet fracture, with intact overlying skin. Patients
in pediatric age group, open fracture or ligamentous
mallet were excluded.
