Understanding Metacarpal Base Fractures
Metacarpal base fractures occur at the base of the bones in your hand and are often caused by direct or indirect trauma. These injuries make up about 30 to 40 percent of all hand fractures. Stability is provided by various ligaments, but fractures near the fourth and fifth fingers are less stable due to joint mobility.
Spotting the Symptoms
If you have a fractured metacarpal base, you might notice swelling, tenderness, and pain, especially when moving your wrist. It's crucial to check for any rotational malalignment, as even slight misalignment can lead to problems down the line. Ensuring the ulnar nerve is functioning properly is also important as it affects finger movement.
How Are They Diagnosed?
Doctors use diagnostic imaging, like X-rays, to confirm metacarpal base fractures. If standard X-rays are unclear, additional views or a CT scan may be needed. Sometimes, ultrasound can help in diagnosing, but it might not provide detailed information about the fracture.
Frequently Asked Questions
These fractures are often the result of direct trauma or a twisting force applied to the hand.
They are usually diagnosed using X-rays or sometimes CT scans.
No, only certain cases with complications require surgical intervention.
Symptoms include swelling, tenderness, and wrist pain.
Key Takeaways
Metacarpal base fractures are common and require proper diagnosis and treatment to prevent long-term issues.
