Who are Dominic Roy and Cooper Bruce? Tulane University students discover new muscle attachment that could reshape hip surgery

Two Tulane University students have made a remarkable discovery that could change how doctors approach hip surgery. Dominic Roy and Cooper Bruce, who were just 19-year-old sophomores when they made the finding in 2024, identified a previously undocumented muscle attachment deep inside the human pelvis. Who would have thoght that a simple cadaver dissection will turn out to be an important anatomical discovery which even their knowledgeable professor could not explain. The research, which was published in the journal Clinical Anatomy, has resulted in new discoveries in the field of hip pain and surgery, proving that there is still so much more to learn about the human body.

HOW DID TULANE STUDENTS ROY AND BRUCE MAKE THE DISCOVERY?

Dominic Roy and Cooper Bruce were both undergraduates studying at Tulane University in New Orleans at the time of this discovery while participating in the university’s anatomy lab.

The students were dissecting cadavers with the help of Dr. R Shane Tubbs, who is a neurosurgery professor and director of surgical anatomy at Tulane School of Medicine.

While conducting the dissection of iliacus and psoas major muscles, Roy came across an unusual structure located in the anterior side of the pelvic bone. Unable to determine what it was, he immediately sought Tubbs' assistance.

"I said, Dominic, I have no idea what that is, but it deserves further attention," Tubbs recalled in an interview published by Tulane University.

The students subsequently examined anatomical literature and textbooks, but found no previous description of the attachment. According to Tulane University, researchers later examined 200 additional donated specimens and identified the attachment in 28% of the sides studied.

Roy, who hails from Madisonville, Louisiana, developed an interest in anatomy during childhood. Bruce, originally from the Philadelphia area, is pursuing a master's degree in neuroscience at Tulane. Their unexpected discovery strengthened both students' interest in medical research and careers in medicine.

"It gave a new purpose to what we were doing there," said Bruce as quoted by Tulane University. "This was the first big research project I was involved in. It felt really cool to experience."

After making the discovey, Roy wasted no time applying to Tulane’s Master of Science in Anatomy program. The discovery also strengthened his determination to pursue a career in medicine.

"This experience really cemented that pursuit," Roy said.

WHAT IS THE DISCOVERY, AND HOW COULD IT IMPROVE HIP SURGERY?

The newly identified structure, called the iliac attachment of the psoas major, is a small muscular attachment located deep inside the pelvis near the front of the hip. Researchers believe it may help stabilize the psoas major, a muscle involved in hip movement.

According to the university, the discovery could eventually help doctors better understand hip pain and conditions such as snapping hip syndrome.

Tubbs stated that diagnosing the attachment using MRI imaging would enable scientists to know whether it affects certain symptoms. Depending on what is found in the future, doctors may opt for physical therapy or surgery to treat patients with such symptoms.

However, its exact role is yet to be determined, and more studies are needed before any medical uses can be identified.
