I am a Consultant Spinal Surgeon at Guy’s and St Thomas’ NHS Foundation Trust, based primarily at the Evelina London Children’s Hospital. I specialise in the management of spinal deformity in children, teenagers and young adults, working within a highly experienced multidisciplinary team treating conditions such as idiopathic scoliosis, neuromuscular deformity, skeletal dysplasia and neurofibromatosis.
My consultant career began in Oxford, where I cared for both adult and paediatric patients with the full spectrum of spinal conditions, including trauma, infection, degenerative disease and complex deformity. This experience provided a strong foundation in spinal surgery and continues to inform my holistic, long-term approach to treating young people as they transition into adulthood.
By way of background, I completed my medical training at Imperial College London with distinction before undertaking specialist orthopaedic training in London. To further strengthen my experience in spinal surgery, I completed a series of high-volume fellowships, including the National Spine Fellowship and advanced deformity fellowships at the Royal National Orthopaedic Hospital and Great Ormond Street Hospital. I was also honoured to receive competitive travelling fellowship awards from both the British Orthopaedic Association and AO Spine, enabling me to visit internationally recognised centres across the United States and Europe. These experiences provided valuable additional training in complex spinal deformity care, as well as exposure to emerging technologies such as 3D navigation and robotic-assisted surgery.
Alongside my surgical practice, I have a particular interest and expertise in non-operative management of scoliosis. I have been actively involved in the BASIS (Bracing in Adolescent Idiopathic Scoliosis) Study, serving as Principal Investigator in Oxford and subsequently as Sub-Investigator at the Evelina. This work has strengthened my commitment to evidence-based pathways that support the right treatment, at the right time, for every patient.
My approach to care is calm, collaborative and patient-focused. I believe that clear communication and shared decision-making are essential to achieving the best possible outcomes. Whether planning surgery or exploring non-operative options, my aim is always to ensure that patients and families feel informed, supported and confident throughout their journey.

Mr Zacharia Silk is professional and clear in patient communications. He makes spinal fusion surgery for scoliosis easy to grasp. Patients report excellent results, with improved posture and movement. This reflects his expert care in spinal conditions.
Dr silk has been amazing, he clearly explained what to expect be the spinal operation and the results are well just amazing. He is a very clever surgeon and is so friendly he explained everything very clearly I can not recommend him enough or express enough how thankful we are for his talents
My recent experience was wonderful. I met Doctor Zacharia again for him to see how well I’ve recovered and he reconnected a few things that would help benefit my day to day life with my back.
Mr Silk has always been very welcoming and treats my daughter in a personalised way taking on board her views. Dr Silk takes his time to listen to my daughter ensuring she has exhausted every question she has leaving no stone unturned. My daughter is feeling very nicely, the actual scoliosis and the scar. As a mother I am extremely happy with the results of the full surgery as a whole.
I wanted to take a moment to express my heartfelt thanks to mostly importantly Dr Zilk and his team Dr Catherine and nurses - Rachael, Amenia and Melissa (Recovery Bestie) for the excellent care and expertise you provided during my daughter pre and post surgery. Knowing she was in such capable hands gave our family great reassurance throughout the process. We are incredibly grateful for the successful outcome and for the professionalism, compassion, and support shown by you and your team. Thank you for making such a positive difference to her life and wellbeing. This was a significant moment for our family and we cannot adequately express how grateful we are for your skill, care, and dedication. Your expertise and the confidence you inspired us pre and post surgery and throughout her journey till date meant a great deal to us. We truly appreciate everything you and your team have done and are delighted with her progress. The only additional feedback we would like to share relates to the timing of the surgery. Having told the surgery will be done in the afternoon on the day of the surgery added to the anxiety and stress for both our daughter and our family. We arrived at the hospital before 6:00am and had to wait for Dr Zilk to finish the first patient and my daughter didn't go for her surgery till 2pm. As she was required to fast from the night before, this meant she went without food for a prolonged period while also coping with the understandable anxiety of a major operation. For a 12-year-old facing significant surgery, this was particularly unpleasant.. This was u...
Read moreMr Silk is extremely professional, kind natured and reassuring. Any questions that we had were answered in full and we felt comforted. Our daughter's operation could not have gone any better, her posture is amazing, she has made a full recovery and the scar has faded so well. Thank you, as our daughter will now lead a normal life now.

Thank you for your kind words. I’m really pleased your daughter has made such a good recovery. It was a privilege to look after her, and I wish her all the very best for the future.
Really happy with my recent visit! been signed off after 2 years, surgery went amazing and has been life changing for me since! couldn’t be happier with Dr Silk and everyone in the team!

It was great to see you doing so well. I’m delighted surgery has made such a difference. Wishing you all the best for the future.
I needed spinal surgery and met Mr Silk before the surgery was due to take place. He explained the procedure and possible side effects and delicate nature of the surgery. He made me feel at ease and i was very willing to take the chance and agree to the surgery. He took great care of me during and after the surgery.
I have been under the care of Mr Silk since November 2024 due to having scoliosis, and I can’t recommend him enough. From the start, he has always shown so much compassion - I have always felt as though he has a genuine interest in my wellbeing, and getting to know me for me, not just my scoliosis. I had spinal fusion in June 2026, with Mr Silk being my surgeon. Throughout the process, he made me feel like I was in safe hands and he made the whole thing feel less daunting. Every day that he could, he came to visit me on the ward after surgery which was so comforting, and he was very uplifting when I had my first post-op appointment. Mr Silk has made such a daunting situation feel lighter, and he truly has had such a positive impact on my life, which is why no words will ever be able to express my gratitude for him

Thank you for such kind feedback. It’s been a privilege to look after you throughout your treatment, and I’m really pleased you felt supported and in safe hands. It’s great to see you doing so well after surgery. Wishing you all the best for the future!
It was an easy and productive experience. I was able to receive quality service and information. All information was clear and met expectations. My questions were answered with detailed and helpful information aswell.
I visited the hospital for a check up after a year since having surgery. Mr Silk has always been so kind and thoughtful, concerned for his patients mental as well as physical wellbeing. Prior to surgery I was very anxious, but I felt reassured being in his care.

Thank you for your lovely words. It was great to see you again and to hear how you’ve been getting on. I’m really pleased you felt supported and reassured throughout your journey. All the best for the future!
Zac is an outstanding spinal surgeon who I have known for many years. He is highly experienced and a very well respected colleague with excellent skills in the treatment of complex spinal cases both elective and traumatic. His bedside manner is fantastic and I have no hesitation in recommending him highly
