28-year-old male present with dorsal hand pain after “losing his temper”
On exam, you note dorsal swelling, tenderness, and deformity
AP, lateral and oblique views are obtained.
There is no rotational deformity but using the lateral view, you note that there is angulation
Measured as the shaft of the metacarpal as compared to the mid-point of the fracture fragment
Acceptable shaft angulation generally accepted to be less than 40°
Patient has greater that acceptable angulation so you have to perform closed reduction
After appropriate pain control consider the “90-90 method.”
Flex the MCP, DIP, and PIP joints to 90 degrees.
This positioning stretches the MCP collateral ligaments helping to optimize reduction
Next, apply volar pressure over the dorsal aspect of the fracture site while applying pressure axially to the flexed PIP joint.
