Conventional treatment of mild slipped capital femoral epiphysis consists of fixation in situ with wires or screws. Recent contributions to the literature suggest that even a mild slip may lead to early damage of the acetabular labrum and adjacent cartilage by abutment of a prominent femoral metaphysis. It has been suggested that the appropriate treatment in mild slipped capital femoral epiphys...

Although generally more common in adults, lower extremity impingement and friction syndromes are also observed in the pediatric age group. Encompassing femoroacetabular impingement, iliopsoas impingement, subspine impingement, and ischiofemoral impingement around the hip; patellar tendon-lateral femoral condyle friction syndrome; iliotibial band friction syndrome; and medial synovial plica synd...

PURPOSE To describe the clinical findings associated with labral ossification (LO), report the outcomes of arthroscopic treatment, and compare this condition to a control group with femoroacetabular impingement (FAI). METHODS A retrospective review of hip arthroscopy patients from 2004 to 2013 was performed to identify patients with a diagnosis of pincer FAI with LO and at least 2 years of fo...

Femoroacetabular impingement (FAI), sometimes termed acetabular rim syndrome, results from chronic mechanical abutment between the femoral head-neck junction and the acetabulolabral complex. Orthopedists have begun to recognize FAI as a cause of pain, instability and progressive hip dysfunction. Because FAI is implicated in the development of osteoarthritis in young individuals, orthopedists ha...

he principles regarding impingement in the natural osseous (anatomic) hip put forth by Ganz et al. are similar in concept to what can occur in the prosthetic hip. To understand impingement, it is helpful to recognize the common mechanisms that cause mechanical abutment in both anatomic and prosthetic hips. In the anatomic hip joint, impingement is a mechanical abutment conflict between the bone...

Background: Femoroacetabular impingement (FAI) is pain due to shape mismatch at the hip joint commonly affecting young athletes, and there are 2 main types depending on which bone has underlying deformity: cam (femoral) pincer (acetabular). Hip arthroscopy an invaluable technique in sports surgeon repertoire, a need for comprehensive tutorial that elucidates best practices nuances. Indications:...

Femoroacetabular impingement is typically described as occurring due to a conflict between the femoral head-neck junction and acetabular rim. A prior case report described an open decompression of the anterior inferior iliac spine (AIIS) due to impingement against the proximal femur. AIIS impingement may be developmental or the result of a prior AIIS avulsion or pelvic osteotomy. We describe 3 ...

BACKGROUND Symptomatic femoroacetabular impingement is a known prearthritic condition. Impingement morphology is poorly defined in the adolescent population. The purpose of this study was to document the prevalence of radiographic impingement morphology in adolescents with no symptomatic hip problems. METHODS Ninety anteroposterior images of the hip in forty-five consecutive adolescents with ...

Abstract Imaging evaluation of the hip joint requires expert knowledge about detailed anatomy and specific injuries. This chapter will include various osseous pathologies that can affect such as stress fractures, osteonecrosis, or subchondral insufficiency fractures. Several types mechanical impingement between components be discussed femoroacetabular impingement, abnormal antetorsion, subspine...

To determine outcomes from arthroscopic surgery for global pincer femoroacetabular impingement (FAI), a large multicenter prospective study investigating arthroscopic surgical outcomes was performed with minimum 2-year follow-up. Global (center-edge angle 40+ degrees) and Focal (center-edge angle 25-39 degrees) cohorts were based on pre-operative radiographs. Pre-operative and intra-operative f...
