Linear external skeletal fixation (ESF) can cause long bone fractures in pets, often through pin tracts or empty drill holes. Careful ESF application is crucial, especially in complex cases.
Area of Science:
- Veterinary Orthopedics
- Small Animal Surgery
Background:
- Linear external skeletal fixation (ESF) is a surgical technique used to stabilize bone fractures.
- Complications can arise from ESF application, including iatrogenic fractures.
Purpose of the Study:
- To investigate long bone fractures in dogs and cats directly resulting from linear external skeletal fixation (ESF) application.
Main Methods:
- A retrospective study was conducted using medical records and radiographs.
- Data were collected from 4 canine and 7 feline cases treated between 1999 and 2011.
Main Results:
- Long bone fractures occurred post-ESF application, either with the device in situ or after removal.
- Fractures consistently occurred at pin tracts or empty drill holes.
- Factors like multiple injuries, revision surgery, and poor owner compliance were common complicating factors.
Conclusions:
- Adherence to ESF application recommendations is vital, particularly in cases with potential complicating factors.
- Leaving empty drill holes is not ideal and may increase fracture risk.
- The study's retrospective nature and small, diverse case numbers necessitate cautious interpretation.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
