journals.lww.com/onsonline/cita… Spine endoscopy isn’t just for stenosis, disc herniation, or spondy. It’s also an option for treating extruded synovial cysts without upfront fusion in select cases. #endoscopy #misspine #spine #neurosurgery #orthopedic
Amazing first day of #issg spring meeting at a beautiful historic Welch library @HopkinsMedicine #spine #research


Biportal endoscopy is my weapon of choice, but I’ll admit, uniportal @gardocki_ray @DrJonOh has its moments. Happy to see @Ghenbot_MD finally join the X. @AANSNeuro #spine #surgery
Great weekend in Boston @AANSNeuro connecting with colleagues and sharing our work under @jwyoonspine characterizing outcomes after endoscopic and open approaches for lumbar discectomy @PennNSG
For @NeurosurgeryCNS, the @jwyoonspine lab demonstrates a unilateral biportal endoscopic transforaminal lumbar interbody fusion for the management of multilevel lumbar spondylolisthesis. ➡️ spr.ly/60192dcyH @RyanTurlip @dakshc99 @Ghenbot_MD @tweetsbyhasan @marceldagli
Two-level TLIF procedures have traditionally been performed through open midline, Wiltse, or tubular approaches. Biportal endoscopic TLIF represents a feasible, safe, and minimally invasive alternative that may reduce the morbidity associated with multilevel lumbar fusion. #spine

Great time at #SRSIMAST25 @SRS_org presenting our work from @PennNSG with @JohnDArenaMD, @dakshc99, and @RyanTurlip. Grateful to Drs. Welch, Ozturk, and Yoon @jwyoonspine for their mentorship. Exciting trajectory for AI-driven applications in spine! #IMAST25 #SRS #Scoliosis
Congratulations to @dakshc99 and @marceldagli from our spinelab both matched into neurosurgery! Marcel is staying at @PennNSG and Daksh is off to @UMneurosurgery @Ricardokomotar @AllanLeviMD @gregbasilmd. Couldn’t be happier for them. Huge milestone and a big future ahead!

The benefit of endoscopic surgery is amplified in fragile patients requiring morbid procedures. Endoscopic techniques enable quicker recovery and faster transition to radiation/chemotherapy, possibly aiding metastatic disease control. sciencedirect.com/science/articl…

Here's @jwyoonspine performing a single-level endoscopic transforaminal lumbar interbody fusion with fluoroscopy-based instrument tracking. Watch the full operative video here: spr.ly/6013vSy7l
For @NeurosurgeryCNS, our #spine team utilized a uniportal endoscopic TLIF technique with concurrent fluoroscopic-based instrument tracking to reduce radiation exposure. @RJ_Chung @jwyoonspine @dakshc99 @tweetsbyhasan @RyanTurlip @marceldagli ➡️ spr.ly/6017thQXT
Check out the latest from our @PennNSG spine team this month in @TheJNS 👏 @jwyoonspine @marceldagli @JGolubovsky @NRM_MD
New for @TheJNS, our #spine team did a study aimed to identify the incidence and implications of pedicle screw loosening at the upper instrumented vertebra after surgical correction of spinal deformity. @JGolubovsky @NRM_MD @jwyoonspine @marceldagli ➡️ spr.ly/6016siObp
Congratulations @MichaelYangMD!!
We are thrilled to share @MichaelYangMD has accepted the role of Associate Program Director for the Neurosurgery Residency Training Program at the @UCalgaryMed @DCNSNeuro He is "looking forward to contributing to the growth and success of our future neurosurgeons!” Congrats!

Meet the new group of #neurosurgery fellows joining us this year!
Thoughts and prayers with the family and friends of the late Dr. Michael Groff. He was liked and respected by all - a great neurosurgeon and even better human.
A very innovative use-case of kinesiometrics and wearable technology for Vestibular Schwannoma treatment and care by @michaelivanmd. #NASBS2025 @NASBSorg @UMneurosurgery @umiamimedicine @IsaacYangMD @UCLANsgy @UCLA_ENT @UCLAHealth @dgsomucla @HarborUCLA @HarborUCLASurg
YO ADRIAN! WE DID IT! What a treat to host Dr. Jim Schuster discussing one of the all-time great movie series - ROCKY!!! youtube.com/watch?v=YxB2jk… podcasts.apple.com/us/podcast/a-n… open.spotify.com/episode/6RPRCx…
Thank you @kevinkumar ! Building upon this review, our team @PennNSG in collaboration with @PennCVI has exciting contributions regarding AVM biology that we hope to share shortly.
Congratulations to @RJabarkheel and team @PennNSG for their publication on targeting the KRAS/MAPK pathway for arteriovenous malformations in @FrontSurgery Rising Stars in Neurosurgery special issue! @cvsection frontiersin.org/journals/surge…
