Objective:
To report the diagnosis and surgical management of a dorsal slab fracture of the fourth carpal bone in a racing greyhound.
Study Design:
Clinical report.
Animal:
Three-year-old, male racing Greyhound.
Methods:
The fracture was not visible on orthogonal radiographs and the diagnosis was made by computed tomography. Open reduction and internal fixation with 2 countersunk 2.0-mm screws inserted in lag fashion was performed via a dorsal approach. Outcome was analyzed objectively by comparing preinjury and postsurgery racing performances.
Results:
Internal fixation resulted in fracture healing and the dog returned to racing recording times similar to those before injury.
Conclusion:
Fractures of the fourth carpal bone may not be visible on standard orthogonal radiographic views and cross-sectional imaging may be required for more accurate identification. Surgical management was successful with the dog returning to preinjury levels of competition.
