This is the astonishing moment a Chinese bone-setting doctor appeared to instantly fix a child's dislocated shoulder.

Footage shows the traditional medic Guo approaching a mother and her son, who was walking behind her as they visited his clinic for a consultation in Henan province, China, on October 30.

Guo got hold of the kid and took his left arm before pulling it and massaging on it to return it to shape in less than a minute.

The boy cried but was reportedly treated. Her mother tried to pay Doctor Guo's assistant money but was refused.

Guo said he was introduced to traditional Chinese medicine when he was only 16 years old because of his father's influence and has been practising orthopaedic for more than 20 years.
