PREFACE

The chapters that will follow share what I consider to be the most important knowledge that I have on any particular topic. My oldest daughter Megan is an orthopedic hand surgeon. I wrote these chapters from my heart to her. Every time I would work on these chapters, I would first put myself in that intimate space to convey something that I care deeply about to someone who I love so much. I was very surprised to see how different this writing is. These chapters include my experience that I’ve learned combining clinical problems with answers generated in the laboratory over many decades. This is the type of information that a maser surgeon-scientist would generate, but combined with an intensely heartfelt message.
