Coxa profunda

Dennis Karimi, Thomas Kallemose, Anders Troelsen, Jakob Klit
INTRODUCTION: In Denmark, 20% of all registered total hip arthroplasties (THA) from 1995 to 2014 has been patients younger than 60 years with primary idiopathic osteoarthritis (OA). It is speculated that hip malformations may be a major contributor to early OA development. It has been shown that hip malformation may compromise implant position and, therefore, identifying and knowing the incidence of malformations is important. Our aim was to assess the prevalence and type of hip malformations in a cohort of younger patients undergoing THA...

BACKGROUND: Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is an example of an abnormality requiring osseous correction with a technically challenging access point. PURPOSE: To report on the patterns of clinical presentation and intra-articular derangements, radiological associations, and minimum 2-year outcomes after hip arthroscopic surgery in patients with a lateral center edge angle (LCEA) >40° and profunda acetabulae in comparison with matched controls with normal acetabular coverage...

BACKGROUND: Femoroacetabular impingement (FAI) is a well-recognized condition that causes hip pain and can lead to early osteoarthritis if not managed properly. With the increasing awareness and efficacy of operative treatments for pincer-type FAI, there is a need for consensus on the standardized radiographic diagnosis. PURPOSE: To perform a systematic review of the evidence regarding imaging modalities and radiographic signs for diagnosing pincer-type FAI. STUDY DESIGN: Systematic review; Level of evidence, 4...

BACKGROUND: Coxa profunda is generally considered an indicator of acetabular overcoverage. However, recent studies have opposed this view. The correlation between coxa profunda and acetabular overcoverage thus remains controversial. The purpose of this study was to investigate the prevalence of coxa profunda and the association between coxa profunda and acetabular coverage based on sex in Japanese subjects using computed tomography. METHODS: We reviewed the computed tomography scans of 151 Japanese consecutive patients (302 hips) aged <50 years who underwent abdominopelvic computed tomography for symptoms unrelated to hip disease...

BACKGROUND: Femoroacetabular impingement (FAI) is a known patho-mechanism that causes hip pain and osteoarthritis (OA) and is considered uncommon in Japan, while secondary OA due to hip dysplasia is considered common. However, no studies have specifically targeted athletes in Japan and/or Asia. This study aimed to determine FAI prevalence using radiological findings among baseball players playing on a professional, Japanese team. METHODS: We retrospectively assessed 63 plain anteroposterior (AP) hip radiographs (126 hips from 47 [74...

BACKGROUND: A diagnosis of femoroacetabular impingement (FAI) requires careful history and physical examination, as well as an accurate and reliable radiologic evaluation using plain radiographs as a screening modality. Radiographic markers in the diagnosis of FAI are numerous and not fully validated. In particular, reliability in their assessment across health care providers is unclear. PURPOSE: To determine inter- and intraobserver reliability between orthopaedic surgeons and musculoskeletal radiologists...

PURPOSE: To determine whether an acetabular labral repair technique would be superior to another repair technique based on clinical outcomes measured by patient-reported outcome (PRO) scores. METHODS: We identified 465 patients who underwent labral base repair or circumferential suture repair from February 2008 to February 2012. The type of repair performed was based on labral size and tear type. The 2 groups were pair matched for age within 5 years, sex, crossover sign within 15%, coxa profunda, Workers' Compensation status, and microfracture (femur, acetabulum, or none)...

In many papers, the diagnosis of pincer-type femoroacetabular impingement (FAI) is attributed to the presence of coxa profunda. However, little is known about the prevalence of coxa profunda in the general population and its clinical relevance. In order to ascertain its prevalence in asymptomatic subjects and whether it is a reliable indicator of pincer-type FAI, we undertook a cross-sectional study between July and December 2013. A total of 226 subjects (452 hips) were initially screened. According to strict inclusion criteria, 129 asymptomatic patients (257 hips) were included in the study...

BACKGROUND: Prior literature has suggested an association between the radiographic signs of femoroacetabular impingement (FAI) and femoral neck stress fractures (FNSF) or femoral neck stress reactions (FNSR). At the time of the writing of this article, no study has described the association of FAI and FNSF/FNSR along with the need for surgical intervention and outcomes. OBJECTIVE: To determine the prevalence of radiographic features of FAI in patients diagnosed with FNSF...

PURPOSE OF THE STUDY: Femoroacetabular impingement syndrome (FAI) represents a mechanical conflict between acetabulum and proximal part of the femur. This disorder may gradually result in the development of the hip osteoarthritis. FAI may be caused by an acetabular retroversion, rarely by coxa profunda or by asphericity of the femoral head and missing femoral head-neck offset respectively. However, a combination of both conditions is the most frequent. Before FAI treatment was adopted as a standard technique for hip preservation at our department, detailed cadaver studies of the vascular anatomy of the hip were performed and the relevant literature was reviewed...

BACKGROUND: Although radiographic coxa profunda has been considered an indicator of acetabular overcoverage, recent studies suggest that radiographic coxa profunda is a nonspecific finding seen even in hip dysplasia. The morphologic features of coxa profunda in hip dysplasia and the frequency with which the two overlap are not well defined. QUESTIONS/PURPOSES: We determined (1) the prevalence of radiographic coxa profunda in patients with hip dysplasia; (2) the morphologic differences of the acetabulum and pelvis between patients with hip dysplasia and control subjects; and (3) the morphologic differences between hip dysplasia with and without coxa profunda...
