The elbow joint links the upper arm bone (humerus) and the two bones of the lower arm (ulna and radius). The elbow joint operates like a door swinging on a hinge and also performs twisting and rotating motions. The elbow is also made up of muscles, nerves and tendons that connect the tissues between muscles and bones.
We invite you to schedule a consultation with an elbow specialist at ONS in our Greenwich, Harrison or Stamford offices if there is a elbow condition that is of concern to you.

Today was my 1st visit to see Dr. Cantlon and he has such a great bedside manor, he’s gentle soft spoken, and easy on the eye lol. In all seriousness I really appreciate him and his staff taking such great care of me, and let me add no wait time which is very important to those of us who work. (5 Star Review on Healthgrades from Dawn M.)
Dr. Cantlon was terrific. He spent time with me, asking me questions, clarifying info and asking me if I understood. Got additional Xrays (tech was great too) which showed no break. So I was happy. Very happy.
Hopefully I don’t have to go back, but Greenwich ONS (Orthopaedic and Neurosurgery Specialists), the staff, and Dr. Cantlon (Hand and Upper Extremity Surgeon) were great. Highly recommended. (Five star review on Google)
Dr. Cantlon is very smart and is so nice. I would definitely go back and recommend. (Patient Survey)
Dr. Cantlon has been great. During our Greenwich Hospital ER visit for a pediatric broken thumb and the ONS follow-up visit, his efficiency, clarity, and bedside manner he had for me and my 11 year old was excellent! (Patient Survey)

She also thought to collect tissue samples during her first surgery, then finding that I had an infection that required 6 weeks of daily antibiotic infusion. I am now 100% healthy and back to normal routines, including yoga (at age 68!) (comment from RateMD)
My experience was fantastic! Dr. Vadasdi was incredible. She did a great job on my shoulder. I strongly recommend that anyone who is facing shoulder surgery to use Dr. Vadasdi.
I have had shoulder surgery before and Dr. Vadasdi is the best and so is the ONS staff! (Patient Review)
I find Dr. Vadasdi to be a genius and compassionate doctor. Her care of me as her patient was outstanding! (Patient Survey)
I have been coming here for at least 15 years and have seen a variety of amazing doctors … Dr. Greene being a favorite in our household for years and would trust him with everything. Recently I broke my elbow and was sent to Dr. Vadasdi. She was amazing! Great with surgery and aftercare. Very compassionate throughout the whole process! Thank you ONS for getting me through everything! (ED)
Dr. Vadasdi: It’s been over a year now since my elbow surgery and I’m back in full swing. Literally! My golf swing- I had my best season to date (over 45 rounds) and achieved my lowest handicap score of 10.8. I can’t thank you enough for applying your surgical skills in repairing my elbow. With PT my recovery was smooth and quick. I was back up and running in just a few months. I feel better and stronger than ever. Your staff from start to finish was professional and compassionate. Thank you. (DT)
Dear Dr. Vadasdi – I neglected to tell you today how much I appreciated the excellent rebuild of my shoulder. You are obviously very talented as my recovery demonstrates. I recommend you to everyone! Thanks again for your time, concern, and operating skills. Have a great New Year! (CS)
Dr. Vadasdi– I was given great information prior to and post surgery. The staff and Dr. Vadasdi were very responsive. I was very pleased with all aspects of the experience. (Anonymous)

Dr. Wei and the people at ONS are the best. I suffered from my first broken bone a few months ago in my hand, right in the middle of my final lacrosse season. From the moment I saw the x-ray to the moment I got the hard cast off, Dr. Wei and his crew were by my side. I made my goals of returning to play the final two games of my season. Without the help from these people, I’m not sure I would have made the comeback that I did. I strongly recommend using ONS. They’re the best in the business. (5 Star Review on Google from E.S.)
Dr. Wei is a wonderful doctor! I came to him with a badly damaged elbow from an old injury I sustained ten years earlier. I ended up needing surgery in December. The surgery went great and I’m living pain free. Dr. Wei explained everything I would go through and was super informative and very compassionate and understanding. My experience with him and ONS was excellent. (5 Star Review on Google from D. O.)
Dr Wei was fantastic. Every aspect of my treatment with him was as good as I could ask for. His initial diagnosis and explanation of my options; his help deciding the best way forward; his execution of the procedure and the immediate aftercare; his empathy and bedside manner; his consideration and accessibility; the time he spent with me; his follow up and focus on my recovery; all of these things were as good as they could be. He really was one of the nicest and most successful surgeons I’ve met. (5 Star Review on Healthgrades)
Dr. David Wei is an excellent physician with a wonderful professional manner. I was very impressed with him and the services I received at ONS. I would highly recommend him as well as ONS. (Patient review from Alison R-K)
Dr. Wei cane into the emergency room at our local hospital to treat our son. A week later, he performed surgery on our boy’s wrist. Weeks later, the wrist is perfectly well now. Thank you Dr. Wei! You have impeccable bedside manner, you are most patient, and we’re truly lucky and thankful to have crossed paths with you. (5 Star review on Healthgrades from William S. in Greenwich), CT
Dr. Wei scores all tens in my book. Throughout my entire experience, he was caring, sensitive, and very thorough. He gave me all the time I needed to have all my questions answered. I never felt rushed. After the surgery, his follow up was outstanding. Even the stafff — each person was lovelier than the next. I’ve never been cared for like that. If I ever need another operation I would go to him in a minute. Dr. Wei is above and beyond. (SF)
I went to four different hand and wrist specialists for the severe pain I felt as a result of a serious car accident I’d had in August, 2015, and no one was able to help me. Then the top hand surgeon at Columbia Presbyterian recommended Dr. David Wei at ONS. Dr. Wei spent more time examining my hand and wrist than all four of the other doctors combined. He was the only one who went beyond the X-rays and used MRI to diagnose that I had small fractures at the end of my ulnar bone and crushed tendons. He was incredibly thorough and talked to me like I was a human being instead of an ailment. He gave me such an incredible level of confidence that he could fix my problem and now, nine weeks after surgery, the pain is practically gone. It was the best treatment I’ve ever received from a physician in my entire life. It’s been a wonderful experience. I would gladly recommend him to anyone looking for a referral. (JS)
I love ONS. They are so above average compared to other doctors and offices. I have had 5 surgeries performed by three of your surgeons. I am seeing Dr. Wei and another doctor at ONS and so far on a scale from 1-10, I have to rate a 10. This includes the whole staff which are all very pleasant and helpful. (Patient Survey)
Dr. Wei was very professional. He took the time to explain in detail everything to my son. He spoke to him like an adult and not a child. He was knowledgeable which was extremely comforting to my husband and I. (Patient Survey)
I am a physician and all 6 of my family members have been using this practice for all of our orthopedic issues. They are amazing and I give big props to Dr. Wei for looking over my Harli two times now, and hopefully the last. (Patient Survey)
Dr. Wei was the third doctor I went to for treatment for my hand. I was so impressed by how caring and skilled he was. He never left me sitting in the waiting room, and I appreciated that respect for my time. Dr. Wei took the time to explain everything to me about my condition and the treatment he proposed. He made sure I understood it all. Dupuytren’s Contracture is difficult to treat. The other two physicians were skilled but they couldn’t solve my problem. Dr. Wei had a special technique that worked for me. I would recommend Dr. Wei, and ONS, to anyone. In fact, I already have. (PB)
I would recommend Dr. Wei without reservation. He is kind and gentle. He did my carpal tunnel surgery and everything went smoothly. I don’t have a single complaint. F.M.
When I first went to Dr. Wei about my Trigger Finger, I told him I was ready for surgery because I’d had the same condition with a different finger a few years ago. If I had been anywhere else, I think the surgeon would’ve rolled me right into the operating room, but Dr. Wei made sure I understood all the non-surgical options first. When I decided to go ahead with the surgery, he took the time to explain that I had the option to forego anesthesia, which I chose because I react poorly to anesthesia. Throughout my entire experience, I felt like I was handled with kid gloves. I couldn’t believe the high level of care and attention I was given for such a little procedure. I have seen other doctors at ONS over the years and my experience has always been very positive. The people at ONS couldn’t be nicer or more accommodating. (DPA)
Dr. Wei was very patient and professional with my six year old daughter. She was very comfortable with him. (Patient Survery)
Dr. Wei was fabulous ! Other than being excellent in his specialty, his bedside manner and his empathy and thoughtful demeanor was first rate. My son now wants to be doctor! Thank-you! (Patient Survey)
Dr. Wei is not only a compassionate person and good ally, he’s a great doctor. I’m 86 years old and as you get older you not only need the best doctor, you need someone with the compassion to help you get through the long haul. He consoled me and took the time to listen and reassure my wife when she called while I was recovering. No one could think of a fall as wonderful, but the way Dr. Wei fixed my wrist and hip was truly outstanding. (JL)
