Canceled: Orthopaedic Surgery Sub-I Rotation

As a result of the COVID-19 pandemic, the School of Medicine has canceled all visiting students to Stanford for 2020-2021.  Students interested in our program should contact Christine Pallasigui.

Welcome to the Team!

Join us in warmly welcoming our newest faculty to the Stanford Ortho Team:

Dr. Aaron Salyapongse

We are pleased to announce the newest member of our faculty as of June 2020, Aaron K. Salyapongse, MD, who joined  our Ortho team as a Clinical Associate Professor and Chief of Orthopaedics at SHC ValleyCare, Pleasanton in the Total Joint Ortho division. When Dr. Salyapongse isn't performing knee and hip replacements, he is spending time with his family. We're excited and honored to welcome him and his vast experience to the team!

Qutoes that resognate with Dr. Salyapongse:

“Families are like branches on a tree. We grow in different directions, yet our roots remain as one
“Success is walking from failure to failure without loss of enthusiasm. - Winston Churchill 






"A" Grades for Patient Safety

Stanford Healthcare teams continue to work diligently to manage the difficulties of COVID-19 while keeping patient care and safety at the forefront.

On April 30, the Leapfrog Group, an independent nonprofit organization committed to driving quality, safety, and transparency in the U.S. health system, issued “A” grades to Stanford Health Care and Stanford Health Care – Valley Care for patient safety.

We are proud of our hospitals and teams, and will continue great efforts towards safety and patient care.

AIMBE College of Fellows Inductee, Dr. Yunzhi Peter Yang

It is with great admiration and celebration that we congratulate Yunzhi Peter Yang, PhD, Stanford Associate Professor of Orthopedic Surgery in Materials Science and Engineering, and Bioengineerings, for being inducted into the American Institute for Medical and Biological Engineering (AIMBE) College of Fellows Class of 2020. This honor is noted as one of highest professional distinctions accorded to a medical and biological engineer, as well as an opportunity to give back and make the fields of medical and biological engineering stronger through advocacy.

AIMBE is the authoritative voice and advocate for the value of medical and biological engineering to society, with a mission to recognize excellence, advance the public understanding, and accelerate medical and biological innovation. AIMBE welcomed a select 157 fellows across 34 countries into the this year’s fellows class, and Dr. Yang was nominated, reviewed, and elected by peers and members of the College of Fellows for “outstanding contributions in developing functionally graded biomaterials and bio-inspired vascularization approaches for musculoskeletal tissue engineering and translational biomedical research.”

Due to the current and unprecedented times, AIMBE cancelled the in-person annual meeting and induction ceremony scheduled for March 29-30, 2020. Thus, under special procedures, Dr. Yang was remotely inducted, along with 156 colleagues, comprising the 2020 AIMBE College of Fellows Class. We congratulate Dr. Yang and his colleagues on this amazing recognition!

Dr. Yang - "In 2010 I attended the AIMBE annual conference for the first time. I was presenting my research as a Coulter Foundation early career translational research awardee and traveling to Capitol Hill to advocate our biomedical research on behalf of AIMBE. Ten years later I myself have the honor to be inducted into the College of Fellows of AIMBE. Quite a journey!"

Stanford Making An Impact In Vietnam

In February 2020, Stanford Orthopaedic Hand Surgeon Dr. Robin Kamal, Orthopaedic Surgery Chief Resident Lauren Shapiro, associated faculty, & residents made their second visit to Hospital 175 in Ho Chi Minh City, where they rejoined surgeons and residents with whom they operated with and taught the last year.

Preparing to treat patients who traveled from all over Vietnam, the team spent their first day in indications clinic where they examined varied and complex cases. Subsequently, the next few days were spent in the operating rooms in the mornings and teaching, lecturing, and reviewing case presentations in the afternoons. The team primarily performed hand and upper extremity cases including distal radius fractures, both bone forearm fractures, distal humerus and humeral shaft fractures and malunions, distal radius mass biopsy, and an elbow instability case, in addition to a case involving multiple tendon transfers for a patient with a radial nerve injury following a motorbike accident. Dr. Lauren Shapiro, Chief Resident -

Overall, it was a great experience – learning and working in a different environment. Already looking forward to going back next year!

Dr. Emily Kraus: Medicine, Running, & Injury Prevention

Dr. Amy Ladd, Chief of Hand & Upper Extremity, Chief of the Robert A Chase Hand Center & Professor, represents Hatshepsut, 5th Pharaoh of the 18th Dynasty of Egypt.

"Tales from the Crypt," A talk about 3-D imaging of a 2000 year old mummy

In wonderful representation of the noble Hatshepsut, fifth Pharaoh of the eighteenth Dynasty of Egypt, Dr. Amy Ladd presented an insightful and incredibly educational talk about 3-D imaging of a 2000 year old mummy child to a substantial Stanford audience on Feb. 20, 2020. The imagery showed the layers of the human body, looking through the shroud of the perfectly preserved mummy. The images would show tissue, muscle, arteries, veins, ligaments, organs, and finally the skeletal system, and revealed some details on how the child lived and died.

Dr. Amy Ladd -   

What an exceptional ability to collaborate with so many fantastic people at Stanford, unlike anyplace on the planet.
My personal highlight was to see so many people across campus who attended.

Interested in Participating in a Study?

Dr. Constance Chu and her research team are looking for participants in their Acute ACL Trial.

In this study, Dr. Chu and her team will use an FDA-approved drug called tranexamic acid (TXA)—already widely used to reduce bleeding during orthopaedic surgeries—to see if TXA treatment right after ACL injury and during ACL surgery can improve knee recovery and cartilage health over 2 years of follow-up. This clinical trial is part of a $10 million grant led by Dr. Chu from the Department of Defense to combat the problem of osteoarthritis occurring after joint injuries.

If interested, please call the research hotline: 650-721-7612.
