What You Need to Know About Metacarpal Shaft Fractures!
Published: Oct 03, 2023
Metacarpal shaft fractures, a common hand injury, can occur due to various traumas. Understanding their patterns and treatment is crucial for effective recovery.
Understanding the Basics
Metacarpal fractures account for up to 50% of all hand fractures. They often result from direct blows, torsional forces, or crushing injuries. These fractures are classified into transverse, oblique, and comminuted patterns, each with unique characteristics and implications.
Spotting the Signs
People with metacarpal shaft fractures usually experience pain and swelling on the back of the hand. Inability to flex the MCP joint is common, and these fractures often occur in the little finger. Visible deformities and tenderness are key indicators that medical evaluation is needed.
Imaging and Diagnosis
X-rays are typically used to diagnose metacarpal shaft fractures. They help determine the angulation and alignment of the fracture. Ultrasound can also assist in detecting fractures, especially when X-rays are inconclusive.
