Disturbance of the upper part (head) of the radius, the outermost bone in the forearm, where it attaches at the elbow, can cause a sudden sharp pain with movement of the forearm or hand.
The upper end of the radius is encased by, and rotates within, an annular ligament, which encircles it and holds it snug against the joint complex at the elbow.
Misalignment of the head of the radius causes painful stress at this joint, and can cause abnormal wear & tear on the annular ligament.
Careful assessment and precise adjustments with the Activator instrument will re-align the bone, relieve the abnormal stress and ease the pain. A compression band should be worn just below the ligamentous attachment to protect the area as it heals.
