Coxa profunda

Thomas L Sanders, Patrick Reardon, Bruce A Levy, Aaron J Krych
PURPOSE: Few studies have evaluated the role of hip arthroscopy in patients with coxa profunda. The purposes of this study are to (1) report functional hip outcomes after arthroscopic treatment of patients with femoroacetabular impingement (FAI) associated with radiographic coxa profunda and (2) evaluate factors associated with poor hip function at minimum 2 years following surgery in this specific cohort. METHODS: This retrospective review included patients with radiographic sign of coxa profunda who underwent hip arthroscopy to treat FAI...

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)...

OBJECTIVE: The goals of a tissue-preserving minimally invasive approach to the hip are to allow early short-term recovery, achieve hip joint stability, minimize muscle strength loss from surgery, spare the peri-articular soft tissues, and allow unrestricted motion in the long term. INDICATIONS: Hip arthroplasty in patients with no pre-existing hardware, with a sufficient space between the acetabular rim and greater trochanter; management of subcapital femoral fractures in older patients...

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...

BACKGROUND: Femoroacetabular impingement (FAI) presupposes a dynamic interaction of the proximal femur and acetabulum producing clinical symptoms and chondrolabral damage. Currently, FAI classification is based on alpha angle and center-edge angle measurements in a single plane. However, acetabular and femoral version and neck-shaft angle also influence FAI. Furthermore, each of these parameters has a reciprocal interaction with the others; for example, a shallow acetabulum delays impingement of the femoral head with the acetabular rim...

BACKGROUND: Human hip morphology is variable, and some variations (or hip morphotypes) such as coxa profunda and coxa recta (cam-type hip) are associated with femoroacetabular impingement and the development of osteoarthrosis. Currently, however, this variability is unexplained. A broader perspective with background information on the morphology of the proximal femur of nonhuman apes is lacking. Specifically, no studies exist of nonhuman ape femora that quantify concavity and its variability...

BACKGROUND: Pistol grip deformity of the proximal femur has been reported as a potential cause of hip pain and early-onset arthritis. The exact incidence of patients with osteoarthritis resulting from femoral acetabular impingement (FAI) is unknown. The purpose of this study was to explore the relationship between radiographic markers of FAI in patients undergoing hip arthroplasty. METHODS: We retrospectively reviewed the radiographs of patients undergoing hip arthroplasty by a single surgeon over a 2-year period...

INTRODUCTION: With excessive acetabular coverage, such as coxa profunda or protrusio, contact between the femoral neck and acetabular rim cause direct damage to the labrochondral junction, and indirect edge loading from a levering effect which may result in hip arthrosis. Arthrosis may be delayed or avoided by addressing the overcoverage and restoring mechanical function of the labrum. We describe four cases of adjunctive complete acetabular labral replacement for circumferential, irreparable labral injury using fresh frozen semitendinous allografts through surgical hip dislocation...
