This is a very interesting article. I was very fortunate to meet Dr. Ladermann during my time in Dallas. We both share an extraordinary passion for shoulder surgery, as well as life in general. After training, I flew to Switzerland to work with him in his hospital. He demonstrated state of the art shoulder surgery techniques unique to Europe while I shared my surgical experience from the US. Serendipitously, we discovered a new surgical technique for performing the reverse total shoulder arthroplasty (an unique shoulder replacement where we replace the shoulder joint as well compensating for shoulder weakness). Subsequently, we published this innovative study on muscle sparing shoulder replacement approach.
