Femoroacetabular impingement is a disorder associated with labrochondral injury and the development of osteoarthritis. Although femoroacetabular impingement is a 3-dimensional disorder with variable size and extent of impingement between individuals, there are 2 primary types of hip impingement: Cam-type and Pincer-type. Cam-type impingement is the result of asphericity of the femoral head-neck...

The purpose of this study was to compare the perioperative complications and traction times in femoroacetabular impingement hip arthroscopy with either a peripheral or central compartment starting point. Sixty patients with femoroacetabular impingement were treated with hip arthroscopy. Thirty patients had a peripheral compartment starting point and 30 had a central compartment starting point. ...

Osteitis pubis is a common form of athletic pubalgia associated with femoroacetabular impingement. Endoscopic pubic symphysectomy was developed as a less invasive option than open surgical curettage for recalcitrant osteitis pubis. This technical note demonstrates the use of the anterior and suprapubic portals in the supine lithotomy position for endoscopic burr resection of pubic symphyseal fi...

BACKGROUND Osteoarthritis of the hip is five to ten times more common in white people than in Chinese people. Little is known about the true prevalence of femoroacetabular impingement or its role in the development of osteoarthritis in the Chinese population. A cross-sectional study of both white and Chinese asymptomatic individuals was conducted to compare the prevalences of radiographic featu...

We herein describe a 34-year-old woman with a persistent left superior vena cava (PLSVC) impinging on the posterior wall of the left atrium, subdivided by a membrane at the distal part of the impingement. In this patient, a much dilated coronary sinus due to the PLSVC resulted in a membrane-like structure in the posterior wall of the left atrium with the appearance of the cor triatriatum in tra...

The range of motion of normal hips and hips with femoroacetabular impingement relative to some specific anatomic reference landmarks is unknown. We therefore described: (1) the range of motion pattern relative to landmarks; (2) the location of the impingement zones in normal and impinging hips; and (3) the influence of surgical débridement on the range of motion. We used a previously developed ...

The purpose of this systematic review is to report current preoperative assessment for femoroacetabular impingement (FAI) including physical examination and imaging modalities prior to hip arthroscopy, and report current imaging measures used in the diagnosis of FAI. The electronic databases MEDLINE, EMBASE and PubMed were searched and screened in duplicate for relevant studies. Data regarding ...

Recent epidemiological studies have demonstrated that radiographic features specific to femoroacetabular impingement appear far more frequently in healthy and asymptomatic cohorts than previously anticipated. It remains unclear how incidental findings should be interpreted clinically. In addition, several authors have suggested that a decreased range of motion is part of the clinical presentati...

Recent developments in hip arthroscopy techniques and technology have made it possible in many cases to avoid open surgical technique for treating pincer-type and cam-type femoroacetabular impingement and rather treating it arthroscopically. Early reports suggest favorable results using arthroscopic techniques. The frequency of complications reported for hip arthroscopy for all indications is g...

EDUCATIONAL OBJECTIVES As a result of reading this article, physicians should be able to: 1. Identify the etiology of femoroacetabular impingement. 2. Assess femoroacetabular impingement on physical examination. 3. Recognize femoroacetabular impingement on imaging studies. 4. Discuss modern techniques to effectively treat femoroacetabular impingement, both open and arthroscopic. Femoroacetabula...
