CONTEXT: Hip injury among young athletes is increasing, especially hip labral tears. Some tears may require surgical intervention, especially if they are associated with boney pathology such as femoroacetabular impingement (FAI). A protocol for nonoperative treatment of the hip labral tears is not well established. OBJECTIVE: To identify current nonoperative treatment options, comorbidities, sports participation, and outcomes of adolescent athletes who were diagnosed with hip labral tears...

BACKGROUND: The frequency of hip arthroscopy for the treatment of acute and chronic chondrolabral pathology and femoroacetabular impingement (FAI) has increased exponentially over the past decade. While surgeon and patient radiation exposure has been well documented in other areas of the orthopaedic literature, little is known about the procedure-specific and cumulative doses affecting the hip arthroscopist. PURPOSE: To determine the mean annual radiation exposure to the hip arthroscopist and the mean surgeon exposure per case...

In this study, quantitative magnetic resonance based measurements were used to evaluate T1ρ and T2 mapping and heterogeneity in femoroacetabular impingement (FAI) patients with acetabular cartilage delamination and to determine the ability of these quantitative MR-based measurements in detecting delamination. Unilateral hip joint MR-scans of 36 FAI patients with arthroscopically-confirmed acetabular cartilage delamination and 36 age, gender and BMI matched controls were obtained. T1ρ and T2 mapping and heterogeneity of the hip joint articular cartilage were assessed in both groups using voxel-based relaxometry (VBR)...

BACKGROUND: Plain radiography, 2-dimensional (2D) magnetic resonance imaging (MRI), and computed tomography (CT) do not precisely display morphology and acetabular coverage in developmental dysplasia of the hip or pincer-type femoroacetabular impingement. Pelvic position and pelvic tilt affect assessment of the acetabular parameters, leading to misinterpretation. OBJECTIVE: We tested a 3-dimensional (3D) CT evaluation script to calculate the crossover sign (COS), acetabular coverage and morphology...

BACKGROUND: The purpose of this study was to determine the relationships between patient factors, mental health status, the condition of the local tissue, magnitude of bony deformity, and preoperative symptoms in a series of femoroacetabular impingement (FAI) patients. METHODS: From our prospective outcomes registry, we identified 64 patients with arthroscopically-treated labral tears and cam deformities. We assessed the correlations between patient factors (age, sex, body mass index, level of education), surgical findings (size of labral tear, presence of chondral lesions), mental health factors (VR-12 mental component score [MCS], depression, and preoperative use of psychotropic and/or opioid drugs), magnitude of FAI deformity (alpha and lateral center edge angles), and preoperative hip dysfunction and osteoarthritis outcome score (HOOS) subscales...

PURPOSE: Identification of the biomechanical alterations in individuals with symptomatic femoroacetabular impingement (FAI) is critical to understand the pathology and inform treatments. Yet hip function in this condition is poorly defined. Squatting requires large hip flexion range and involves motion toward the position of hip impingement; thus, it is likely to expose modified biomechanics in these individuals. This study aimed to determine whether hip and pelvis biomechanics differ between individuals with and without symptomatic FAI during an unconstrained deep squat and a constrained squat designed to limit compensation by the pelvis and trunk...

Stable slipped capital femoral epiphysis (SCFE) is the most common disease in the adolescent hip, with an estimated frequency of 10.8 in every 100,000 individuals. Recent studies of the biomechanics of femoroacetabular impingement indicate that small anatomical deformities of the hip arising from SCFE can potentially cause permanent acetabular chondral damage. There is no consensus about the best treatment option, especially for cases of moderate or severe chronic slippage (Southwick classification). Some authors recommend treatment with fixation in situ, in the belief that remodeling of the residual deformity of the femoral neck during growth allows proper function of the hip joint...

Mitsunori Kaya
Cam impingement is caused by jamming of an abnormal femoral head with an increased radius into the acetabulum during motion. Therefore, the elevation of the contact pressure during the motion is suspected to be an essential pathology of femoroacetabular impingement. However, there is no method to quantify the hip contact pressure during motion. The purpose of this Technical Note is to introduce a technique to measure the hip contact pressure during arthroscopic surgery. The author believes that the current technique will be a useful tool for the detailed investigation of the pathophysiology femoroacetabular impingement and thorough evaluation of its therapeutic significance...

Musculoskeletal pathologies in the pelvis encompass a wide variety of lesions including femoroacetabular impingement, athletic pubalgia, ischiofemoral impingement, and apophyseal avulsion injuries. Magnetic resonance imaging is the noninvasive imaging modality of choice for the diagnosis and management of these lesions. In this article, the authors discuss the nonneoplastic musculoskeletal lesions in the pelvis, with illustrations and relevant case examples.

Femoroacetabular impingement is the condition whereby parts of the proximal femur mechanically collide with the acetabular rim leading to adjacent and contrecoup acetabular damage. Evidence is growing that at least for cam impingement, and perhaps less so for pincer impingement, there is a relation to the development of osteoarthritis. It has been demonstrated that surgery for impingement can improve function and decrease pain. Intuitively, it would then make sense that surgical intervention would prevent further degeneration...

REVIEW
David M Peck, Lisa M Voss, Tyler T Voss
Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in adolescents, occurring in 10.8 per 100,000 children. SCFE usually occurs in those eight to 15 years of age and is one of the most commonly missed diagnoses in children. SCFE is classified as stable or unstable based on the stability of the physis. It is associated with obesity, growth spurts, and (occasionally) endocrine abnormalities such as hypothyroidism, growth hormone supplementation, hypogonadism, and panhypopituitarism. Patients with SCFE usually present with limping and poorly localized pain in the hip, groin, thigh, or knee...

OBJECTIVE: Femoroacetabular impingement (FAI) is a commonly recognized condition in athletes characterized by activity-related hip pain and stiffness, which if left untreated can progress to hip osteoarthritis. The aim of the study was to determine the effect of symptomatic FAI on performance in young athletes based on the hypothesis that athletes with FAI would show deficits in performance compared with healthy controls. DESIGN: The functional performance of a cohort of preoperative, competitive sportsmen with symptomatic FAI (FAI group, n = 54), was compared with that of a group of age, sex and activity-level matched controls (n = 66)...
