An interesting case showcasing a malfunctioning afferent input loop.
A young man with a diagnosis of torticollis (which was really involuntary movement) and winging of the scapulae.
I diagnosed the cause of his nerve interference on his first visit and here you can see the follow-up.
An apicectomy is done when there is an infection in the root of a tooth. Instead of a root canal the tip of the root is cut off and mercury amalgam is put in its place.
Who knew an apicectomy could have such effects?
