Damage or impairment to the radius bone in the forearm.
Medical records documenting the original radius fracture and its treatment are the foundation of the evidence. Imaging such as X-rays, CT scans, or MRI reports that show nonunion, false movement at the fracture site, malunion, bad alignment, or the presence and measurement of bone loss are directly tied to the rating criteria. A report noting the amount of bone substance lost — specifically whether it reaches one inch (2.5 centimeters) or more — and whether marked deformity is present would support the higher ratings for lower-half nonunion.
Records identifying which arm is your dominant arm help VA apply the correct Major or Minor percentage. Physician or orthopedic specialist notes describing the location of the nonunion — upper half versus lower half of the radius — are also relevant. Statements from you or people who know you describing how the arm functions in daily tasks or work activities can round out the picture of how the condition affects you.
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.
