Summary
Isolated capitate fractures are rare and often missed. Computed tomography (CT) is crucial for diagnosing this oblique intraarticular capitate fracture, which is not previously described.
Area of Science:
- Orthopedic Surgery
- Radiology
- Anatomy
Background:
- Isolated capitate fractures are uncommon and frequently misdiagnosed.
- Standard radiographic views may not detect subtle capitate injuries.
- Literature review reveals most capitate fractures are transverse or associated with other carpal injuries.
Observation:
- A unique case of an isolated oblique intraarticular capitate fracture is presented.
- The fracture was initially missed on standard radiographs.
- An incidental finding of an old ulnar styloid process fracture was noted.
Findings:
- Computed tomography (CT) successfully identified the oblique intraarticular capitate fracture.
- This specific fracture pattern has not been previously documented in medical literature.
- Diagnosis of capitate fractures may require advanced imaging modalities.
Implications:
- Highlights the potential for missed capitate fractures in clinical practice.
- Emphasizes the diagnostic utility of CT for complex carpal bone injuries.
- Suggests a need for increased awareness of rare capitate fracture presentations and their management.
