Li Gets Nationwide Recognition for Discoveries in Hand Biomechanics

Zong-Ming Li, PhD, a professor of orthopaedic medical procedures and director of the Hand Research Laboratory at the University of Arizona College of Drugs – Tucson, has been selected by the American Modern society of Mechanical Engineers to acquire the 2022 Savio L-Y. Woo Translational Biomechanics Medal for his work on human palms.

In accordance to the American Culture of Mechanical Engineers, the Savio L-Y. Woo Translational Biomechanics Medal recognizes an personal who has translated meritorious bioengineering science to medical exercise by way of investigation, education and learning, and experienced enhancement, and with support to the bioengineering group.

For Dr. Li, obtaining an award named just after Savio L-Y. Woo is specifically significant. Early in his vocation, Dr. Li put in time in Dr. Woo’s Musculoskeletal Exploration Center at the College of Pittsburgh.

“Dr. Woo is a huge in orthopedic sports medicine and bioengineering. I realized from him to target on a scientific challenge, operate a lab, provide the job and mentor foreseeable future generations,” recalled Dr. Li, who also is the William and Sylvia Rubin Endowed Chair in Orthopaedic Research and holds a joint appointment in biomedical engineering at the UArizona University of Engineering.

The medal will be offered at the Summer Biomechanics, Bioengineering, and Biotransport Conference in June, exactly where Dr. Li will provide a presentation on his perform.

Dr. Li appears to be at the hand and wrist as a result of an engineer’s lens to understand how they do the job and produce engineering remedies to issues this kind of as carpal tunnel syndrome. According to the American Academy of Spouse and children Doctors, roughly 3% of adults have carpal tunnel syndrome, which is characterized by tingling, numbness or weakness in the affected hand.

Getting nonsurgical options

“The Hand Study Laboratory’s mission is to comprehend how the regular hand operates and how to repair the hand when its purpose is disturbed,” Dr. Li claimed. “As an engineer, it is so fascinating to review the human system — in our case, the complexity of the hand and wrist.”

The carpal tunnel is a area in the wrist as a result of which the median nerve travels from the arm into the hand, passing beneath the transverse carpal ligament. If the ligament pushes versus and irritates the nerve, it can induce carpal tunnel syndrome.

The issue may perhaps be originally taken care of with bodily therapy, wrist splints or corticosteroid injections. If individuals methods fall short, physicians may well recommend carpal tunnel release operation to minimize the ligament’s force on the nerve. The surgical procedures could also result in a weakened grip, although, and in some individuals, carpal tunnel syndrome can return.

“In the U.S., a half-million persons are receiving surgery each yr, but it is not a ideal option,” explained Dr. Li, who also is the vice chair for analysis in the Department of Orthopaedic Surgical procedure, affiliate director of the UArizona Arthritis Middle and a member of the BIO5 Institute. “We asked, ‘Can we relieve the median nerve with out operation?’ That basic question has kept us busy for a long time.”

Dr. Li and his exploration crew, alongside with colleagues at the Cleveland Clinic, have made a product that intermittently compresses the ligament and brings about it to bend in a way that cuts down force on the adjacent nerve. In early trials, the wrist manipulation improved signs and symptoms in members.

Dr. Li mentioned discovering how to manipulate the house in the carpal tunnel to make far more area for the nerve is a single of his proudest achievements mainly because it has possible to assistance countless sufferers.

“To obtain this easy theory that nobody else in the area is contemplating of – that is remarkable,” he reported. “We want not only to recognize clinical complications, but also come across answers. Bringing this translational perform to fruition normally takes years of perform.”

Dr. Li and his collaborators are in search of grants to advance to the next phase of investigation, exactly where they hope to enroll patients at numerous sites across the state to test the effectiveness of the device on a larger sized scale and identify the best method for its use.
