The Essential Guide to Diagnosing Metacarpal Head Fractures
Published: Oct 04, 2024
Accurate diagnosis of metacarpal head fractures is crucial for effective treatment and recovery. Learn how these injuries are diagnosed.
Imaging Techniques for Diagnosis
When a metacarpal head fracture is suspected, a standard hand series of plain radiographs is usually ordered. This includes anteroposterior, lateral, and oblique views to get a comprehensive look at the injury. For skilled practitioners, point-of-care ultrasonography can provide a quick, preliminary diagnosis, but it might not offer detailed fracture information.
Advanced Imaging Options
If radiographs and ultrasound don't reveal the fracture but it's still suspected, a non-contrast CT scan is the next step. CT scans offer a detailed view of the bone and can confirm or rule out an occult fracture. While MRI is useful for soft tissue injuries, CT is preferred for bone-related concerns.
Special Views for Complex Cases
In cases where a collateral ligament avulsion fracture is suspected but not visible, a Brewerton view might be used. This involves specific positioning of the MCP joint to better visualize the injury. This specialized view helps in detecting subtle fractures that standard views might miss.
