"Heal you, of course... Silly girl." She said as she took her wand and with a silent spell, she dislocated the girl's shoulder. This was no doubt causing the Ravenclaw a LOT of pain.

"A dislocated shoulder occurs when the humerus separates from the scapula at the glenohumeral joint. As the most maneuverable joint in the human body, the shoulder is the joint most vulnerable to dislocation. Approximately half of major joint dislocations seen in St Mungos are of the shoulder.

"Prompt professional medical treatment should be sought for any suspected dislocation injury. Usually, a dislocated shoulder is kept in its current position by use of a splint or sling. A pillow between the arm and torso may provide support and increase comfort. Ice may help reduce pain.

"What Nurse Numel and Myself do is focused on returning the shoulder to its normal position via processes known as reduction. Several methods are used to manipulate the bone and joint from the outside. A variety of techniques exist, but some are preferred due to fewer complications or easier execution. This is done with the wand at the left of the arm, then make a slow slash downward, then up with a jerk, using the following incantation."

She demonstrated the wand movement and said "Resarcio!" She performed it perfectly.

"The spell also gives a dose of Pain Potion, so there is no more pain. Any questions?"
