Is there any strength in elbow extension? If it is strong, and there is weakness in simply extending the wrist and fingers, consider whether the radial nerve is impinged at the pronator teres muscle of the forearm? The location is in the upper 1/3 of the forearm extension. If confirmed, a release surgery would be sufficient.

(Dr. Zhang Xiangning solemn reminder: due to the inability to meet the patient, can not fully understand the condition, the above recommendations are for reference only, the specific diagnosis and treatment, please be sure to go to the hospital under the guidance of a doctor!)
