We took care of this gentleman last week who had a severe spinal cord compression at C34 with severe arm weakness, including loss of fine motor.
About 18 hours after surgery, on the first postoperative day he was showing off to my 2 physician assistants how strong his pinch grip had improved overnight.
He went home very thankful, and on the way to recovery.
Surgical time was 90 minutes.
