This special issue of Topics in Geriatric Rehabilitation examines topics related to conditions of the hip region in our aging population. When considering the etiology responsible for occurrence of hip pain in these individuals, the initial thought is very often osteoarthritis (OA) of the hip joint. Although OA is very often a cause of hip pain, numerous other causes should be considered. Topics that are discussed in this issue include examination, differential diagnosis, pathological concepts, risk factors, conservative, operative, and postoperative treatment of conditions affecting the hip region.

A systematic approach is presented to aid clinicians in classifying patients with hip pain into categories to help direct treatment decisions. Conservative treatment options and the related evidence for the treatment of hip OA are discussed. A case study examining the complex clinical scenario of hip OA and pelvic floor dysfunction in a female patient is presented. The relatively newer and controversial hip resurfacing procedure is discussed along with the well-established total hip arthroplasty surgery. Current concepts in rehabilitation for patients undergoing total hip arthroplasty will be provided for clinicians who treat patients in the postoperative environment. A summary of research examining in vivo force and pressure data during specific activities is reviewed to help guide the progression of rehabilitation activities.

Hip fractures are a significant concern for the aging population. Risk factors, classification of fractures, surgical options, and clinical presentation related to hip fractures are discussed. Postoperative rehabilitation principles and considerations across the spectrum of clinical settings are described.

Many members of our aging population remain active throughout the majority of their life span. Golf remains a very popular sport among many geriatric individuals. The final article in this issue discusses topics related to the effects of golf on the hip complex in aging individuals.

I hope this issue will help provide clinicians an effective approach to evaluation and treatment of older individuals presenting with pain in the hip region. I also would like to offer my most sincere gratitude to all the authors who contributed their time and knowledge to this endeavor.
