The aim of this study is to compare
the clinical outcomes of delta wire technique and
extension block pinning in terms of distal
interphalangeal joint active flexion, extension lag, union
time, the visual analogue scale and Crawford criteria.
Trying to find out the best surgical intervention to treat
Methods: In order to prepare this systematic review
and meta-analysis, we adhered to the PRISMA
statement's requirements. Using pertinent keywords, a
computerized literature search was done in Cochrane
Central, Web of Science, and PubMed. Utilizing Review
Manager Version 5.4.1 for Windows, data was retrieved
and synthesized from the records after they had been
checked for admissible studies. Case studies, clinical
trials, and randomized control trials about mallet
fracture in individuals older than 18 were all included.
We took open fractures out, and the injury happened
more than four weeks after the initial injury.
Results: This study provides evidence that extension
block technique has better outcome regarding active
distal interphalangeal flexion than the delta wire, but
there is no difference between the two techniques
regarding degree of extension lag, union time, and
visual analog scale and Crawford criteria.
Conclusion: Further high quality randomize control
studies between the two techniques is needed to find out
the best surgical way to treat mallet fracture.
