BACKGROUND: Intra-articular hip pathologies are thought to be associated with the development of hip and groin pain. A better understanding of the relationship between symptoms and imaging findings may improve the management of individuals with intra-articular hip pathologies. OBJECTIVE: To undertake a systematic review and meta-analysis to determine the prevalence of intra-articular hip pathologies in individuals with and without pain. METHODS: Seven electronic databases were searched in February 2017 for studies investigating the prevalence of intra-articular hip pathologies using MRI, MRA or CT...

Hip arthroscopy as we know it today developed over the last 15 to 20 years, yet its true beginning is far more dated. Initially developed as a means of removing loose bodies or as a means of lavage, hip arthroscopy was not utilized to treat femoroacetabular impingement (FAI) until much later. Its usefulness as a means of treating FAI did not arise until hip impingement was understood to be causal in the development of degenerative changes of the labrum and articular surfaces. As our understanding of FAI grew, the tools for treating it developed in tandem...

Transient osteoporosis of the hip(TOH) is classified as a type of bone marrow edema syndrome. TOH is lack of previous study and there is still controversy about his pathogenesis. In recent years, with the development of multi-discipline, such as imaging, pathology, molecular biology, the study has found that the pathological mechanism is complex, while its mechanism is still not clear, which need further research. This paper summarizes the research progress on the pathogenesis of TOH from neurogenic, osteonecrosis, abnormal vascular function, subchondral fracture, heredity and regional acceleration and son on...

Mechanisms underpinning self-selected walking speed (SSWS) are poorly understood. The present study investigated the extent to which SSWS is related to metabolism, energy cost, and/or perceptual parameters during both normal and artificially constrained walking. Fourteen participants with no pathology affecting gait were tested under standard conditions. Subjects walked on a motorized treadmill at speeds derived from their SSWS as a continuous protocol. RPE scores (CR10) and expired air to calculate energy cost (J...

INTRODUCTION: Cadaveric studies indicate that adductor magnus is structurally partitioned into at least two regions. The aim of this study was to investigate the direction-specific actions of proximal and distal portions of adductor magnus, and in doing so determine if these segments have distinct functional roles. MATERIALS AND METHODS: Fine-wire EMG electrodes were inserted into two portions of adductor magnus of twelve healthy young adults. Muscle activity was recorded during maximum voluntary isometric contractions (MVICs) across eight tests (hip flexion/extension, internal/external rotation, abduction, and adduction at 0°, 45° and 90° hip flexion)...

As forensic scientists and physicians, forensic pathologists are duty-bound to perform their examinations with integrity and professionalism. The practice of medicine requires knowledge regarding the history and presentation of the patient. In forensic pathology, the history includes scene and other investigative information, and the decedent's medical and social history. Such information is important for the correct certification of the cause and manner of death. Herein, the authors present a case originally thought by police and death investigators to represent a sexual-assault-related homicide, as an elderly female's body was found partially nude, and apparently beaten, on the muddy floor of her horse barn...

The Hereditary Spastic Paraplegias (HSP) are a group of heterogeneous disorders with a wide spectrum of underlying neural pathology, and hence HSP patients express a variety of gait abnormalities. Classification of these phenotypes may help in monitoring disease progression and personalizing therapies. This is currently managed by measuring values of some kinematic and spatio-temporal parameters at certain moments during the gait cycle, either in the doctor´s surgery room or after very precise measurements produced by instrumental gait analysis (IGA)...

Metal-on-metal hip resurfacing arthroplasties (MoMHRAs) have a high failure rate due to pseudotumour formation. It is not certain whether pseudotumours in bilateral MoMHRAs form on the basis of an adverse reaction to metal debris (ARMD) that is entirely due to a local innate and adaptive immune response to Cobalt-Chrome (Co-Cr) wear particles. To determine if there is a systemic component to ARMD in bilateral MoMHRAs, we examined the histology of ARMD in unilateral and bilateral MoMHRAs revised for pseudotumour and determined whether implant survival differed between these two groups...

A vesicocutaneous fistula (VCF) is a tract that is formed abnormally between the bladder and the external surface of the body. VCF results in a great deal of inconvenience, discomfort, and physical disability for the affected patient. This condition can be caused by extensive trauma with pelvic bone fracture, radical pelvic surgery, irradiation of pelvic malignancies, hip arthroplasty, a large bladder calculus, and various other pathologies. The management of VCF should be approached on a case-by-case basis because of the complexity of the disease...

INTRODUCTION: Developmental dysplasia of the hip (DDH) is still a common and important disorder of childhood, with a prevalence of 0.1 to 2/1000 children. Using ultrasonography (US) in screening of DDH reduces the rates of open reductions and complications. In the current study, we aim to detect the optimal time for US examination for detecting DDH to prevent unnecessary repeating US examinations and treatments. METHODS: Children referred to US examination for a healthy child screening program, according to the health policy of our country, are included in the current prospective study...

BACKGROUND: Arthroscopic surgery is becoming popular in the management of hip pathologies. There are numerous studies describing the outcomes of the treatment of athletes with this method. These outcomes are generally found to be excellent. Yet there are little data in the literature with respect to the arthroscopic treatment of nonathletes. The objective of our study is to compare the outcomes of the femoroacetabular impingement (FAI) treatment between athletes and nonathletes using arthroscopy, using two popular scales...

BACKGROUND: Gluteal tendinopathy (GT) and hip osteoarthritis (OA) are the most common causes of hip pain and associated disability in older adults. Pain and altered walking biomechanics are common to both conditions. This study aimed to compare three-dimensional walking biomechanics between individuals with unilateral, symptomatic GT and HOA. METHODS: Sixty individuals with symptomatic unilateral GT confirmed by magnetic-resonance-imaging and 73 individuals with symptomatic unilateral HOA (Kellgren-Lawrence Grade ≥ 2) underwent three-dimensional gait analysis...

BACKGROUND: Beyond obesity-related comorbidities, overweight patients have a high risk of developing osteoarticular pathologies. Moreover, weight loss following bariatric surgery induces a decrease in fat mass but also in muscle mass, thus affecting the physical capacities of these patients. Functional rehabilitation is a solution to correct these imbalances. The aim of this study was to evaluate the effectiveness of a functional rehabilitation program after bariatric surgery. METHODS: Twenty-three patients with severe obesity (BMI = 37...

We explored the mechanism of early stage osteonecrotic femoral head collapse by analyzing and comparing different regions in human osteonecrotic femoral head samples. Eight osteonecrotic femoral heads (ARCO II-III) were obtained from patients undergoing total hip arthroplasty. Bone structure was observed and evaluated by micro-computed tomography (CT) scans and pathology. Osteoblast and osteoclast activities were detected by tartrate-resistant acid phosphatase, alkaline phosphatase, and immunofluorescent staining...
