Summary
Closed reduction using extension-block Kirschner wire effectively treated mallet fractures with large fragments or subluxated distal phalanges, showing good to excellent outcomes in most patients.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Traumatology
Background:
- Mallet finger injuries often involve large fracture fragments or distal phalanx subluxation.
- Effective treatment is crucial for restoring hand function and preventing long-term complications.
Purpose of the Study:
- To evaluate the efficacy of closed reduction with extension-block Kirschner wire for treating mallet fingers.
- To assess the functional outcomes and morbidity associated with this technique.
Main Methods:
- Fourteen patients with mallet finger injuries underwent closed reduction and fixation with an extension-block Kirschner wire.
- Follow-up evaluations were conducted at a mean of 9 months post-treatment.
Main Results:
- Eight excellent, four good, one fair, and one poor outcome were reported based on Crawford's criteria.
- The technique demonstrated simplicity and ease of reduction compared to other methods.
Conclusions:
- Closed reduction with extension-block Kirschner wire is a simple and effective treatment for mallet fractures.
- This method offers a low morbidity rate and favorable outcomes for patients with displaced large fracture fragments or subluxated distal phalanges.
