In clinical practice, we are frequently faced with this problem, especially when treating athletes participating in sports that require repetitive lower- limb movements, kicking, and sudden changes of speed and direction during the sporting activity. To better understand this challenging multifactorial condition, a compre- hensive approach is mandatory. Patients often refer to vague and diffuse symptoms that can be attributed to a variety of pathological entities; hence, the diagnosis and management of the underlying pathological processes remains a challenge. Furthermore, the pain is frequently not attributable to a single etiological cause, but is derived from the possible association of mul- tiple pathologies, thus requiring a differential diagnosis. The surgeon should carefully consider the differential diagnosis, as it is also important to take into account that groin pain can have musculoskeletal as well as visceral causes. This book, representing the latest updates of current knowledge on this subject, is an indispensable resource that will assist the reader to recognize and treat groin pain. The reader will also become acquainted with many aspects of basic science that have improved the differential diagnosis and treatment of this syndrome. The contributing authors are experts in the field and share with the reader their experiences and surgical insights. This book is a state-of-the-art guide for those starting in the field of groin pain syndrome, as well as for experi- enced specialists. Rome, Italy Vincenzo Denaro v Preface Groin pain syndrome is an important current clinical topic in sports medi- cine, but the syndrome is still not well known and its characteristics are debatable, while its patterns of diagnosis and treatment are often imprecise and fragmentary. The classification and identification of a diagnostic taxonomy for the syn- drome have not yet found a common interpretation. Therefore, gaining actual agreement among the different specialists that face the clinical issues of this entity is often difficult. The terminology used in the literature includes, often inappropriately, a very large number of terms and definitions. Therefore, there is a need to orga- nize and better classify the numerous clinical symptoms that can constitute groin pain; only in this way will it will be possible to reach a correct diagnosis and then provide the correct treatment. This syndrome covers a range of symptoms, localized in the groin area, that often have a multifactorial etiopathogenesis, and as a consequence, treat- ment will involve practitioners from different medical specialties. The syn- drome provides a clear example of how interaction and cooperation among different professional approaches, sharing patterns of diagnosis and proce- dures, may be fundamental in improving treatment. This book aims to summarize the state of the art in the treatment and diag- nosis of groin pain syndrome in an innovative way, considering the set of problems from different professional points of view and searching for a shared synthesis. In the first chapter, a new classification of groin pain syndrome is sug- gested for a more precise differential diagnosis; this is based on the results of the recent Consensus Conference, held in Milan on February 5, 2016, with the participation of major Italian experts in the field. The groin area is extremely complex, both from the anatomical and bio- mechanical points of view, and these topics will be analyzed, together with radiological diagnoses, to complete the introductory part of the book. The next part of the book describes orthopaedic pathologies that can cause groin pain; the different pathologies are examined both in terms of the diagnosis and in terms of the relevant treatment; we focus on labrum lesions; chondral damage; and pathologies of the central, peripheral, and peritrochanteric compartments. The main pathology that causes groin pain is certainly femoroacetabular impingement, and above all, cam impingement, where a femoral bump leads vii viii Preface to an articular conflict between femur and acetabulum, with associated bio- mechanical alteration; this produces compensatory stresses in other anatomi- cal areas, such as the pubic symphysis, the sacroiliac joint, and the abdominal lining. Also, groin pain can often be caused by visceral pathologies that are very important to understand and evaluate. The so-called sports hernia is quite frequent in sportsmen, and is often not well diagnosed or well treated. Therefore, there is a need for correct diagnos- tic and therapeutic approaches; these are explained in Part II of this book. Many tendon and muscle pathologies are also a frequent cause of groin pain, and in Part III of this book, these are discussed in depth, with particular attention paid to the adductor tendons, ileopsoas tendons, and abdominal muscles that can frequently be involved in atypical groin pain. The pubic bone, both at the symphyseal joint and in the bone itself, can be the target area of compensatory stress, and therefore all possible pubic pathologies are examined. Furthermore, we must never underestimate the neurological causes of groin pain, such as those that are well identified in the so-called nerve entrap- ment syndrome; these causes are discussed and investigated. The end of the book contains chapters dedicated to rehabilitation; conser- vative rehabilitation is discussed above all, with particular attention given to strengthening and stretching exercises, physical therapy, and hydrotherapy. With regard to postoperative rehabilitation, different chapters will discuss rehabilitation after arthroscopic hip surgery, abdominal surgery, and tendon surgery, with indications and in-depth analysis of the most up-to-date and efficient protocols. I believe that, in the long run, this book will make a complete and thorough contribution to a multidisciplinary approach to the groin pain syndrome, and may therefore help specialists in different fields to better understand the vari- ous and often overlapping causes of groin pain. The scientific co-operation of distinguished international and Italian experts, whom I kindly thank for their important contributions, has allowed us to reach our target; that is, to define the state of the art in our knowledge of the groin pain syndrome and then to suggest new diagnostic, therapeutic, and organizational models for the condition.
