Outcomes of Patients with Tendinous Mallet Finger Injury Managed with DIPJ Extension Splinting vs Axial Pinning A Descriptive Study

Main Article Content
Abstract
Background. Mallet finger, a common finger injury, results from damage to the distal extensor tendon, causing a flexion deformity at the distal interphalangeal joint. While conservative treatment with splinting is often effective, surgical intervention using Kirschner wire fixation may be necessary for complex cases or non-compliant patients.
Objective. This study compared the outcomes of two treatments for tendinous mallet finger: splinting and pinning. Researchers analyzed patient demographics, distal interphalangeal joint range of motion, clinical outcomes, and complication rates between the two groups.
Methodology. We retrospectively reviewed patients diagnosed with tendinous mallet finger injury managed conservatively or surgically from 2018 to 2022 in a tertiary hospital.
Result. Both surgical and conservative treatments were effective, as shown by the excellent total active motion scores and satisfactory qDASH (Disabilities of the Arm, Shoulder, and Hand) outcomes in both groups. However, when comparing the Miller and Crawford criteria, the surgical group consistently showed slightly better functional outcomes.
Conclusion. Both treatments yielded similar results for range of motion, extension lag, and flexion loss, making them equally effective. However, axial pinning may result in better subjective improvement and satisfaction.
