We retrospectively examined the long-term outcome of 96 asymptomatic hips in 96 patients with a mean age of 49.3 years (16 to 65) who had radiological evidence of femoroacetabular impingement. When surveillance commenced there were 17, 34, and 45 hips with cam, pincer, and mixed impingement, respectively. Overall, 79 hips (82.3%) remained free of osteoarthritis for a mean of 18.5 years (10 to 4...

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. ...

INTRODUCTION: Rotational acetabular osteotomy (RAO) has been recognized as an useful procedure, especially for early stage of osteoarthritis of the hip, with satisfactory intermediate and long-term results. In RAO, it is important to rotate the acetabular roof sufficiently, contributing to improvement of the acetabular roof coverage. On the other hand, femoroacetabular impingement due to acetab...

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...

BACKGROUND Coxa profunda is commonly viewed as a radiographic parameter that is indicative of pincer-type femoroacetabular impingement, and this finding can impact diagnostic and surgical decision-making. Validation of coxa profunda as a measure of pincer-type femoroacetabular impingement has not been rigorously analyzed. Our hypothesis was that coxa profunda is a very common radiographic findi...

Over an eight-month period we prospectively enrolled 122 patients who underwent arthroscopic surgery of the hip for femoroacetabular impingement and met the inclusion criteria for this study. Patients with bilateral hip arthroscopy, avascular necrosis and previous hip surgery were excluded. Ten patients refused to participate leaving 112 in the study. There were 62 women and 50 men. The mean ag...
