Book excerpt: What a great opportunity it is to participate in the body of information advancing the study of musculoskeletal medicine. As the physician, the readers can attest that didactic presen- tions of musculoskeletal complaints are at a minimum during undergraduate training. The advancement of individual clinical understanding of this field many times is left to the practitioner. Out of imagination, passion, or frustration, we the musculosk- etal practitioners seek to improve our abilities to provide better clinical diagnostic endeavors. The hip and pelvis is an area in musculoskeletal and sports medicine that provides continued mystery. It is the last great bastion of the unknown. Our hope in bringing together many excellent clinician authors is to provide the basis for improved approach to the patient and athlete who have complaints involving the hip and pelvis. Each chapter begins with a clinical case which is probably similar to the patients you see in your practices. Each chapter provides an approach to the diagnosis of hip and pelvis pain and dysfunction that hopefully is easily applicable to your daily activities as a practitioner. Most importantly, we hope that the material contained within this book helps you provide improved care, satisfaction, and function for your patient athletes. Jimmy D.
