Diagnosing Capitate Fractures: What You Should Know
Published: Aug 25, 2024
Diagnosing capitate fractures can be tricky, but understanding the process can lead to better outcomes. Here's what you need to know.
Initial Imaging Techniques
Diagnosis often starts with standard wrist X-rays, including anteroposterior, lateral, and oblique views. These can show fractures and help identify dislocations. However, X-rays sometimes miss capitate fractures, requiring further investigation.
Advanced Imaging for Confirmation
If X-rays don't reveal a fracture but suspicion remains, CT or MRI scans are used. CT scans provide a detailed view of the bone structure, while MRI helps detect soft tissue injuries and occult fractures.
Understanding Fracture Patterns
Capitate fractures are categorized into body fractures, avulsion tip fractures, and shear depression fractures. Advanced imaging helps determine the exact type and extent of the fracture for appropriate treatment.
