Cam morphology of the proximal femur is an abnormal contour of the femoral head-neck junction present in approximately 15% to 25% of the asymptomatic population, predominantly in males. Alpha angle and femoral head-neck offset ratio are 2 objective measurement tools that define cam morphology. Both primary (idiopathic) and secondary cam deformity develops through distinct mechanisms. The cause of primary (idiopathic) cam morphology remains incompletely understood. Mounting evidence suggests that idiopathic cam morphology develops during adolescence through alterations in the capital femoral epiphysis in response to participation in vigorous sporting activity...

The 21 muscles that cross the hip provide both triplanar movement and stability between the femur and acetabulum. The primary intent of this clinical commentary is to review and discuss the current understanding of the specific actions of the hip muscles. Analysis of their actions is based primarily on the spatial orientation of the muscles relative to the axes of rotation at the hip. The discussion of muscle actions is organized according to the 3 cardinal planes of motion. Actions are considered from both femoral-on-pelvic and pelvic-on-femoral perspectives, with particular attention to the role of coactivation of trunk muscles...

The hip is a complex anatomic structure composed of osseous, ligamentous, and muscular structures responsible for transferring the weight of the body from the axial skeleton into the lower extremities. This must be accomplished while allowing for dynamic loading during activities such as gait and balance. The evaluation of hip pain and periarticular pathology can be challenging because of the complex local anatomy and broad differential diagnosis. Recent advancements in the evaluation and surgical treatment of hip pathology have led to a renewed interest in the management of these disorders...

The primary purpose of this review article is to discuss the role of diagnostic, corticosteroid, hyaluronic acid (HA) and platelet rich plasma (PRP) in the treatment of osteoarthritis (OA) and femoroacetabular impingement (FIA). These treatments play an important biological role in the non-operative management of these conditions. Two independent reviewers performed an search of PubMed for articles that contained at least one of the following search terms pertaining to intra-articular hip injection-local anaesthetic, diagnostic, ultrasound, fluoroscopic, image guided, corticosteroid, HA, PRP, OA, labral tears and FAI...

PURPOSE: To critically evaluate the evidence for arthroscopic management of chondral defects in the hip through a systematic literature review. METHODS: A systematic literature review was performed to identify all articles addressing the arthroscopic management of chondral defects about the hip. Case reports, open techniques, and those associated with osteonecrosis were excluded. Articles were assessed for sample size, location, severity, and size of chondral defects, and the surgical technique...

BACKGROUND: Recent studies have questioned the importance of the iliotibial band (ITB) in lateral knee pain. The Ober test or modified Ober test is the most commonly recommended physical examination tool for assessment of ITB tightness. No studies support the validity of either Ober test for measuring ITB tightness. PURPOSE/HYPOTHESIS: The purpose of this study was to assess the effects of progressive transection of the ITB, gluteus medius and minimus (med/min) muscles, and hip joint capsule of lightly embalmed cadavers on Ober test results and to compare them with assessment of all structures intact...

BACKGROUND: The anatomy of the acetabulum has been described extensively in the literature, but radiographic acetabular guidelines have not been well established. This study provides a radiographic map of acetabular landmarks in the hip. PURPOSE/HYPOTHESIS: The purpose of this study was to quantify the precise radiographic location of arthroscopic landmarks around the acetabulum. The hypothesis was that their locations were reproducible despite variability in the anatomy and positioning of pelvic specimens...

BACKGROUND: Prospective studies have reported that abnormal movement patterns at the trunk, hip, and knee are associated with noncontact anterior cruciate ligament (ACL) injuries. Impaired hip strength may underlie these abnormal movement patterns, suggesting that diminished hip strength may increase the risk of noncontact ACL injury. PURPOSE: To determine whether baseline hip strength predicts future noncontact ACL injury in athletes. STUDY DESIGN: Case-control study; Level of evidence, 3...

The surgical management of symptomatic femoroacetabular impingement (FAI) generally is indicated after the failure of a trial of nonsurgical treatment. Surgical planning includes an assessment of the labrochondral pathology as well as of the acetabular and proximal femoral bony deformity. Advanced articular cartilage disease generally is associated with poorer outcomes. Surgical hip dislocation and hip arthroscopy have been used, with favorable early outcomes and low complication rates. Careful patient selection is important in predicting the success of the surgical management of symptomatic FAI...

Imaging studies play a key role in establishing the diagnosis of femoroacetabular impingement (FAI). When clinical examination is suggestive of FAI, radiographic evidence should confirm the diagnosis. Imaging findings must be evaluated in the context of the patient's clinical presentation and recreational activities. Plain radiographic evaluation remains the initial diagnostic modality. Three-dimensional imaging such as MRI and CT often is obtained for the evaluation of labral and cartilage pathology, definition of bony anatomy, and surgical planning...

STUDY DESIGN: Controlled laboratory study, cross-sectional. Objectives To characterize hip muscle forces and powers during running, and to determine how these quantities change when altering step rate for a given running speed. BACKGROUND: Hip musculature has been implicated in a variety of running-related injuries and, as such, is often the target of rehabilitation interventions, including resistance exercises and gait retraining. The differential contributions of the hip muscles to the task of running are not well understood, and may be important for recognizing the biomechanical mechanisms of running-related injuries and refining current treatment and prevention strategies...

BACKGROUND: Radiographic features specifically related to the occurrence of femoroacetabular impingement (FAI) appear to be highly prevalent in the asymptomatic population. It remains unclear, however, how these incidental findings should be interpreted clinically and which other variables might differentiate between true incidental findings and preclinical patients. PURPOSE: To study the association between cam and overall hip morphological characteristics and range of motion in impingement patients, asymptomatic patients (healthy patients with radiographic features specific to FAI), and healthy controls...

Understanding normal anatomy of the hip is important for diagnosing its pathology. MR arthrography is more sensitive for the detection of intra-articular pathology than noncontrast MR imaging. Important elements of the osseous structures on MR imaging include the alignment and the marrow. Acetabular ossicles may be present. Normal variations involving the cartilage include the supra-acetabular fossa and the stellate lesion. Important muscles of the hip are the sartorius, rectus femoris, iliopsoas, gluteus minimus and medius, adductors, and hamstrings...
