Reduced movement or function of the thigh at the hip joint, including rotation or side motion.
To support a rating for thigh impairment, medical records that document range-of-motion measurements are the most direct form of evidence. For the 20% level, an examination would need to show that abduction is lost beyond 10 degrees. For either 10% level, records would need to show that adduction is restricted enough that you cannot cross your legs, or that rotation on the affected leg is restricted so you cannot toe out more than 15 degrees.
Findings from a VA or private orthopedic examination that include goniometric measurements of abduction, adduction, and rotation are particularly useful. Imaging such as X-rays may help explain why motion is restricted. Your own statements, or statements from people who observe you daily, describing difficulty with activities that require spreading or rotating the leg, such as walking, sitting, or stepping into vehicles, can help show how the limitations affect your function.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
