High success rate reported for non-image guided hip injection

TORONTO — Using anatomic landmarks proved effective to perform intra-articular hip injections with an anterior approach but without image guidance, according to a study presented at the International Society of Arthroscopy, Knee Surgery & Orthopaedic Sports Medicine Congress.
“Non-guided hip injection is safe and reproducible,” Omer Mei-Dan, MD, said here.
The technique’s accuracy relies on finding the point at which the line of the patient’s hip in full neutral position meets the line of the patients’ foot in neutral position and without external rotation, Mei-Dan said.

In the study, patients were supine on a fracture table. Completing the injection involved other key steps, which included identifying landmarks like the tip of the greater trochanter, relative to the point identified, placing inner and outer needles and a syringe to produce an “air arthrogram” and using fluoroscopy to affirm the needles and air were in the joint.
He said, however, it may require five to 10 injections to execute the injection properly with this technique at first. Furthermore, Mei-Dan recommended trying it in an operating room setting initially.
Among the 55 patients Mei-Dan and his coauthors did the needle placements on (36 men, 19 women), 51 placements were correct for a 93% success rate, he said.
