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...

abstract backgrounds: subacromial impingement is a common cause of shoulder pain and many patients with this condition recover with conservative management. the most commonly used modalities of nonoperative treatment include activity modification, anti-inflammatory medication and subacromial injection of steroid and ultrasound and physical therapy programs. this study assessed the value of phys...

Combined hip arthroscopy and limited open osteochondroplasty for anterior femoroacetabular impingement. Background: A variety of surgical techniques have been introduced for the treatment of femoroacetabular impingement,

Both cavitation erosion and liquid impingement erosion are phenomena that can cause pipe wall thinning in power plants. The Code for Power Generation Facilities, Rules on Pipe Wall Thinning Management, was published by the JSME (Japan Society of Mechanical Engineers) in 2005. The code says that cavitation erosion shall be prevented either in the design stage or by daily inspection. On the other...

INTRODUCTION To analyze the X-ray and magnetic resonance imaging (MRI) features of acetabular labral tears, so as to improve the recognition of the disease. MATERIAL AND METHODS Imaging features of 19 patients with acetabular labral tears confirmed by arthroscopy were analyzed retrospectively. All cases were examined by X-ray. Fourteen patients underwent MRI examinations. RESULTS Seventeen ...

BACKGROUND AND PURPOSE Indications for acromioplasty are based on clinical symptoms and are generally supported by typical changes in acromial morphology on standard radiographs. We evaluated 5 commonly used radiographic parameters of acromial morphology and assessed the association between different radiographic characteristics on the one hand and subacromial impingement or rotator cuff tears ...

Femoroacetabular impingement (FAI) is a progressive pathology of hip joint affecting young adults causing hip pain and osteoarthritis. FAI results from contact secondary to abnormal morphology of proximal femur, femoral head-neck junction and acetabular rim. Two types of femoroacetabular impingement have been described: Pincer ve Cam impingement. Pincer impingement is caused by the overcoverage...

Introduction With repetitive ankle sprains, reparative tissues can be generated and often become hypertrophied and entrapped in the ankle joint. They induce and aggravate synovitis, sometimes causing soft tissue impingement of the ankle. Although comparatively rare, anteromedial soft tissue impingement is becoming increasingly reported on the radiologic and orthopedic literature (1-5). However,...

Periprosthetic or bony impingement in total hip arthroplasty (THA) has been correlated to dislocation, increased wear, reduced postoperative functionality with pain and/or decreased range of motion (ROM). We sought to study the accuracy and assess the reliability of measuring bony and periprosthetic impingement on a virtual bone model prior to the implantation of the acetabular cup with the hel...
