Elbow instability with excessive, uncontrolled movement at the joint.
To support a rating for a flail joint, medical records and examination findings would need to show gross instability of the elbow, such as abnormal or uncontrolled movement at the joint that reflects loss of its structural integrity. An orthopedic or VA examination documenting this finding in the dominant or nondominant arm would be central evidence. For the lower level — marked cubitus varus or cubitus valgus deformity or an ununited fracture of the head of the radius — imaging such as X-rays can document the angular deformity or confirm that a fracture of the radial head has not healed. Examination findings describing the visible or measurable deformity also support this level. Statements from you or people who know you describing how elbow instability or deformity affects your ability to lift, carry, or perform tasks at work and in daily life can help show the functional impact of the condition at either level.
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.
