Diagnostic accuracy of plain radiography to identify synovial penetration in horses with traumatic limb wounds.

If findings of a series of plain radiographs suggest synovial penetration in horses with a wound near a synovial cavity, then synovial penetration is likely, but the absence of plain radiographic findings does not rule out synovial penetration. The use of a metallic probe during radiography may be helpful. However, plain radiography should be interpreted cautiously, and clinical decision making should also include other techniques.
