First you must determine which hand you will use to locate the IM injection site by the position the patient is in, for example if the patient is on their right side you would use your right hand to find the landmarks. So using the example, a person is lying on their right side so you would take your right hand and place it on their greater trochanter, depending on the length of your fingers you would then place your index finger on the anterior superior iliac spine or point your finger in that direction with the thumb pointed at the groin, all other fingers should be pointed at the patient's head. Once your hand is in position move your middle finger back along the iliac crest towards the buttock as far as you are able to go. This forms the triangle with the index and middle finger and the center of that triangle is the injection site for a ventrogluteal injection.
The treatment of any form of bursitis depends on whether or not it involves infection. Infection of a shoulder bursa is uncommon, and bursitis that develops there is usually from injury. Bursitis that is not infected (from injury or an underlying rheumatic disease) can be treated with ice compresses, rest, and antiinflammatory and pain medications . Occasionally, it requires aspiration of the bursa fluid. This procedure involves removal of the fluid with a needle and syringe under sterile conditions and can be performed in the doctor’s office. Sometimes the fluid is sent to the laboratory for further analysis. Noninfectious shoulder bursitis can also be treated with an injection of cortisone medication into the swollen bursa. This is sometimes done at the same time as the aspiration procedure. Physical therapy can sometimes be used to aid the recovery from bursitis, especially when it is accompanied by a frozen shoulder .
