Board certified plastic surgeon
Hand fellowship trained

I attended medical school at the Johns Hopkins School of Medicine, and then moved to southern California for my Plastic Surgery residency at Loma Linda University. I spent additional time training at the University of Southern California at Keck/LAC to gain expertise in hand surgery and microsurgery. I now practice at the University of California at Irvine where I specialize in breast reconstruction, hand surgery, and complex microsurgical reconstruction.

This is constriction band syndrome. This very rare condition happens while babies are still growing in the womb: part of the sac that surrounds the baby gets wrapped around the baby and cause damage as they grow. This process can even cause amputation of fingers and toes, like they did for this patient. The band got so tight that it even fused her fingers together! To treat this, I carefully separated her fingers and used skin from her belly to help reconstruct them. Even though these fingers are short, she can do everything she wants to with them! For those in the know, this is acrosyndactyly. Even though it might look at first glance like Apert’s syndrome it is totally different! I use the lower abdomen as my donor site, in the same location as a future csection or abdominoplasty scar. All patients/parents provide consent for sharing.

Can’t believe this was already more than a week ago! What a wonderful meeting of the American Association for Hand Surgery, American Society for Peripheral Nerve, and American Society for Reconstructive Microsurgery in Chula Vista. was strongly represented with .ida.fox as the president of ASPN, and the many incredible alumni of the program in leadership roles around the country. Can’t wait to see everyone next year in Miami!

This is a ligament injury of the thumb. Ligaments are strong tissue that hold our bones and joints together, and when they are damaged our joints can hurt, or even be unstable, like in this case. You can see in the video on the left side how I can push this patient’s thumb away from her hand. The ligament damaged here is called the ulnar collateral ligament, or UCL. When this ligament is torn quickly, like in an accident, it is sometimes called a Skier’s thumb. When it is worn out slowly overtime from repetitive motion, it is sometimes called a Gamekeeper’s thumb. To fix these injuries I need to either repair the ligament or replace it with strong material that will support the joint. We often use small anchors that hold the repair to the bone. For those in the know, you can see the important parts of examination of the UCL including stabilization of the metacarpal prior to stressing the joint, and testing the joint in full extension to isolate the total joint stability (inclusive of the volar plate, and both accessory and proper collateral ligaments) and in 30 degrees of flexion to assess the isolated stability of the proper collateral ligament. (All patients provide consent to share photos.)

Thank you for the incredibly opportunity through the traveling fellowship!! Thank you to the nerve nerds around the world who hosted me and shared ideas and opened their clinics and operating rooms to me. I had an amazing time.

This is a pediatric trigger finger. It might not be something you realized can happen to children (this is a very common problem for adults) but it can! This happens when the tendon gets swollen - we don’t know why - and it no longer slides smoothly through the finger. The tendon normally lives in a special tunnel called the tendon sheath. Swelling of the tendon can cause the finger to get stuck in a bent position, or make it hard to straighten out and snap or click when it straightens. Sometimes kids get better with time, and sometimes the problem doesn’t go away even with splints and hand therapy. This patient’s finger was getting stuck all the time, and so their parent’s decided it was time for surgery. To fix the problem, we need to make more space for the tendon to move in the finger. This can be done by widening the tunnel that the tendon moves through. Sometimes in children we also have to make the tendon a little smaller too (for those in the know, resection of a slip of the FDS tendon is commonly needed in pediatric cases, unlike adults). You can see in the first video how the finger ‘snaps’ when I try to straighten it. You can swipe to see a photo of the swelling in the tendon, and another video showing how much better the finger moves after surgery! All patients and/or their parents provide permission to share the stories and videos 😊.

Brachial plexus birth injury treatment is a passion for me. (Part of my recruitment to WashU was to provide this type of care). This condition happens in the birthing process and can cause damage to the nerves in the baby’s neck. The brachial plexus (BRAY-key-el PLEK-sis) is a cluster of nerves in the neck that become the nerves of the arm. These nerves control movement and feeling in the shoulder, arm, hand, and fingers. (Palsy means weakness, and brachial plexus birth palsy means arm weakness and loss of motion.) One or two of every 1,000 babies born have this condition. Most infants with brachial plexus birth palsy will recover, but need daily physical therapy to help. However, a small percentage of children do not recover, and need urgent surgery to repair these nerves. I always hope that children will get better without needing my help, but I love being able to be there for them when they do. I am lucky to do these cases with my awesome partners in neurosurgery and orthopedic surgery. It truly is the dream team! We are a high volume center and do at least one of these cases every month.

What a fabulous evening at the third annual cocktails and cases event, a + celebration of our best cases each year. My excellent and glamorous partner and APD has outdone herself arranging this elegant event. We were joined by our community plastic surgery partners (🥰 ) and came out from Colorado to give us a talk to kick off the night! I can’t wait to see the theme next year.

Another weekend, another cadaver course. Thank you to for giving me the opportunity to teach hand fellows around the country about the importance of excellent technique in nerve repair and how to incorporate nerve transfers into their reconstructive algorithms. It’s alway a joy to share knowledge with young surgeons!

What a treat to celebrate the portrait unveiling for a legendary surgeon who has been a mentor, role model, trail blazer and world changer. Scott Levin, beyond being an incredible surgeon and human being, has pushed the specialists in orthopedic and plastic surgery to work more closely with one another in the hand, nerve, and limb salvage space. We are stronger together. 💪🏻 AND even more wonderful to have one of my beloved mentees as my date. I can’t wait to see what is next for you .tiourin 💕

Would you believe that thumb is made out of a toe? Swipe for a video of the motion for this little boy. I am so thrilled for him and his family. He had two surgeries to get to this point. I’ve showed you cases before where I move an index finger to make a thumb for patients who are born without one, or who are born with very underdeveloped thumbs. Not every family is willing to have that surgery. For those patients I can remove a toe bone to help stabilize their underdeveloped thumbs. This surgery only provides support for their finger, it does not recreate any of the muscles or ligaments that are important for thumb motion. So that means that they need to have more surgery later to help make the thumb move. And that is exactly what I did for this young boy. His parents did not want a pollicization (moving the index finger) and so instead I used his toe bone to reconstruct his thumb (you can swipe to see the X-rays showing how this looks, and how the foot looks now too!) After he healed we did the next surgery, called an opponensplasty, to help give his thumb more motion. This operation borrows an extra tendon from the ring finger, and you can look through my old posts to see some videos of how that looks. I also changed the shape of the space between his index finger and thumb to make it easier for him to grab things. In the future I will transfer some fat from other parts of his body to improve the shape of the thumb. For those in the know: to honor cultural preferences and still provide the best opportunity for function for my patients, I will perform free non-vascular 4th metatarsal transfer for patients under 4, and free vascularized 2nd toe MTPJ transfer for older children (l’ve posted a case of this before.) A pollicization is without a doubt the superior functional surgery, and achieves reconstruction in a single stage as opposed to multiple steps, however not all families choose it.

Highlights of my first few months here at include my first brachial plexus birth injury case here at Wash U. It is so great to start building back this part of my practice: it is a condition I am very passionate about treating! Something fun and new here is that I have multidisciplinary partners who are also invested in providing cutting edge care - Dr. McEvoy in neurosurgery and Dr. Wall in orthopedic surgery 💕. We all bring a different set of eyes to these cases and I know the outcome will be the very best as a result.
