A challenging case of cervical chordoma causing severe canal stenosis and encasing the left vertebral artery. Only possible through the expertise and seamless coordination of our multidisciplinary team at @UCSF, resulting in a good outcome for our patient. @ChordomaFDN
What happens when a rare spinal tumor grows around critical nerves and a major artery? That’s the challenge facing a multidisciplinary team of @UCSFHospitals specialists in this complex cervical #chordoma case. youtube.com/watch?v=u1wuo1Xj… @jwyoonspine @UCSFimaging @UCSF_OHNS

Many thanks to @RushMedical's Vincent Traynelis, MD, for joining us for Spine Day! This year's hands-on course, led by @jwyoonspine and @DrDiGiorgio, focused on training our residents in advanced instrumentation, decompression, reconstruction, and deformity-correction techniques.

Wow, what an amazing work you’re doing Clara! @Apple
In a new @NatureNeuro study, researchers at @UCSF and @UCBerkeley identify how the brain encodes approach-avoidance decisions in the orbitofrontal cortex, finding that activity in this region predicts a person's decision before they act: nature.com/articles/s41593-0… @ChangLabUcsf

Thankful to be at an institution where pushing boundaries is valued! I’m humbled to care for patients with metastatic cancer who face difficult decisions about undergoing surgery, often to preserve their neurological function. We will continue to push forward for them.
Endoscopic spine surgery has applications in reconstruction as well as decompression, says @UCSFHospitals neurosurgeon Jang Won Yoon, MD (@jwyoonspine). Read more in @BeckersSpine about how he's been using the technique to treat metastatic spine tumors ➡️ beckersspine.com/spine/how-e…

Thank you @DeanChouMD! Honored to be invited to speak at @LSRSspine. The society brings together both neuro and ortho spine surgeons together under one roof for a honest, open and frank discussion. We need more meetings like this.
Great start to the 2026 Lumbar Spine Research Society @LSRSspine meeting with the ICL by Jang Yoon, MD, from @NeurosurgUCSF
