coxarthrosis

BACKGROUND: Atraumatic femoral head necrosis is a rare pathological change of the femoral head. It is characterized by local necrosis of the cancellous bone as a result of reduced blood supply to the bone. Even today it remains unclear how to assess the hardness of the necrosis, whether it is soft tissue that is easily removed, or hard tissue that is difficult to resect. METHODS: Femoral heads with primary coxarthrosis were selected as a comparison group. For this purpose, 49 femoral heads obtained during total hip arthroplasty surgery with either condition (23 femoral head necrosis, 26 coxarthrosis) were transferred to the testing laboratory in fresh condition...

PURPOSE: Developmental dysplasia of the hip is still a prevailing secondary cause of early hip osteoarthritis in Jordan. Dysplastic coxarthrosis can result in significant and disabling hip pain with impaired patient's functionality. Due to this significant morbidity, patients ultimately need total hip arthroplasty, which offers the best functional outcome. Significant anatomical aberrances do exist in such hips as a result of old dysplasia; such pathoanatomical changes can complicate an already difficult surgery and lead to significant intraoperative blood loss and haemoglobin drop postoperatively...

Introduction Total hip arthroplasty (THA) in patients with residual poliomyelitis (RP) is a surgical challenge. Dysplastic morphology, osteoporosis and gluteal weakness hinder orientation, increase fracture risk and reduce implant stability. The aim of this study is to describe a series of patients with RP treated by THA. Material and methods Retrospective descriptive study of patients with RP treated with THA between 1999 and 2021 in a tertiary hospital, with clinical and radiological follow-up and functional and complication evaluation until present or death, with a minimum of 12 months...

BACKGROUND: Hip arthroplasty is a frequently performed procedure in orthopedic surgery, carried out in almost all health structures for two main issues: fracture and coxarthrosis. Even if volume-outcome relationship appeared associated in many surgeries recently, data provided are not sufficient to set surgical thresholds neither than closing down low-volumes centers. QUESTION: With this study, we wanted to identify surgical, health care-related and territorial factors influencing patient' mortality and readmission after a HA for a femoral fracture in 2018 in France...

UNLABELLED: Developmental dysplasia of the hip (DDH) is the cause of approximately one third of secondary coxarthrosis. Anatomy alterations make it difficult to place a total hip prosthesis in its anatomical position and for it to be stable in the long term; there are several techniques to achieve this goal. In the present work we used autograft of the femoral head (shelf graft or reinforced roof), to improve the coverage of the acetabular component with favorable results. MATERIALS AND METHODS: 16 cases were included in 14 patients with a diagnosis of DDC (13 women and 1 man), the mean age was 44...

OBJECTIVES: Clinical, radiological and functional results of the first Spanish series of patients undergoing total hip arthroplasty assisted by Mako® (Stryker) robotic arm at the Hospital Clínico San Carlos in Madrid. MATERIAL AND METHODS: Prospective and descriptive study analyzing the first 25 patients who underwent robotic-assisted THA at the HCSC, with a minimum follow-up of 4 months. Demographics, imaging studies (Mako® processing, Rx and CT), clinical parameters, functionality (Modified Harris) and associated complications were evaluated...

In order to study the features of surgical approaches for hip arthroplasty in patients with dysplastic coxarthrosis, an analysis of the course of the disease was carried out in 80 patients with dysplastic coxarthrosis who were treated at the Therapeutic Surgical Clinic of the Azerbaijan Medical University. The average age of the patients was 52.2±0.65, 51.6±0.55 and 50.3±0.71 years with overweight (BMI>=25 and <30. In order to determine the activity of the inflammatory process and the effectiveness of treatment a complete blood count and assessment of ESR, total WOMAC index and visual analog pain scale VAS were performed after 6 and 12 months...

OBJECTIVE: In this study, our aim was to evaluate the results obtained by conservative treatment of femoral neck fracture in patients with untreated Crowe type 4 coxarthrosis with high dislocation. METHODS: This was was a retrospective study done at the Orthopaedics and Traumatology Clinic in a secondary care public hospital between 2002 and 2022, in Türkiye. Femur neck fractures were evaluated in six patients who had untreated Crowe type 4 coxarthrosis with high dislocation...

Since Offierski and MacNab reported a close association between the hip and spine as hip-spine syndrome in 1983, many studies on spinal alignment in hip disorders have been conducted. Notably, the pelvic incidence angle (PI) is the most important parameter and is determined by the anatomical variations in the sacroiliac joint and hip. Studies on the association of the PI with hip disorders can help in understanding the pathophysiology of hip-spine syndrome. A PI increase has been observed during the evolution of bipedal locomotion in humans and in the acquisition of gait during child development...

Osteoarthritis is a degenerative joint disease associated with pain, loss of function and reduced quality of life. Concomitant psychological disorders can significantly influence treatment outcomes. Therefore, we aimed to answer the following research questions: (1) How has the incidence of primary coxarthrosis and gonarthrosis developed over the last decade? (2) How high is the prevalence of osteoarthritis patients with concomitant psychological diagnoses? (3) Which psychological comorbidities are most prevalent in coxarthrosis and gonarthrosis patients, respectively? For this cross-sectional study, a dataset provided by the Federal Statistical Office (Destatis) consisting of annual, Germany-wide ICD-10 diagnosis codes from 2009 to 2019 was analysed...

PURPOSE: To evaluate the association between global spinal malalignment and rapid progression of hip arthrosis. METHODS: This was a retrospective, case-control study including 90 patients, contributing 90 hips, who underwent hemi- or total hip arthroplasty at our institution. For analysis, hips were classified into a rapid progression group, defined as ≥ 2 mm destruction of the femoral head or loss of the hip joint space within a 12-month period (n = 30), and a non-rapid progression group, defined by no observable hip disease progression over a period more than 12 months (n = 60)...

Incorrectly developed acetabulum and subluxated hip joint may cause many problems for proper implantation of endoprosthesis. The aim of this work is to assess the radiological results of offset restoration and selection of endoprosthesis implant in a dysplastic hip joint. The study group consisted of patients who had a surgery in the period between 2016 and 2018. All of them had a cementless total hip endoprosthesis. The group consisted of 91 patients (96 hip joints), with an average age of 42 years (31-47 years)...

OBJECTIVES: This study aimed to examine whether there is an association between hip osteoarthritis and vitamin D receptor gene FokI polymorphisms. PATIENTS AND METHODS: In this case-control study, a total of 162 volunteers (43 males, 119 females; mean age: 62.4±9.3; range, 50 to 80 years) were included between March 2011 and March 2012. The patient group included 80 individuals with a diagnosis of coxarthrosis. Eighty-two individuals with normal hip, low back, and sacroiliac joint examination were included in the control group...

CASE: A 70-year-old woman presented with severe trunk deformity, gait disturbance, and bilateral hip pain. Radiography and magnetic resonance imaging revealed severe spinal kyphosis, bilateral osteoarthritis of the hip joints, and lumbar canal stenosis. A 2-stage corrective surgery for the treatment of spinal kyphosis was performed. Subsequently, the spinopelvic alignment changed remarkably. The spinal symptoms and radiographic parameters improved postoperatively, and bilateral hip pain and range of motion also showed improvement...

INTRODUCTION: Klippel-Trenaunay syndrome (KTS) affects the development of blood vessels, soft tissues (such as skin and muscles), and bone. It is a rare cause of severe degenerative joint disease at an early age. Orthopedic interventions in these patients bring numerous difficulties for various reasons. Up to this point, only six cases of attempted total hip arthroplasty (THA) in patients with KTS have been reported in the literature. The two most recent cases were prematurely aborted due to excessive bleeding and imminent risk of exsanguination...

Objective - to justify the use of hip endoprosthesis techniques in dysplastic coxarthrosis depending on the type of dysplasia according to Crowe JF. The study is based on the analysis of hip replacement in 390 patients with dysplastic coxarthrosis, who underwent 436 endoprosthetics. There were 192 patients with type 1 dysplasia according to Crowe, type II - 142, type III - 38 and type IV - 18 patients. The age of patients ranged from 15 to 61 years and averaged 43 years. Pathology was prevalent in women, which accounted for 90 %...

BACKGROUND: Within a timeframe of 8 years (2008-2016), 38 patients have undergone total hip replacement surgery for coxarthrosis or aseptic necrosis secondary to acetabulum fractures. MATERIALS AND METHODS: The study included 27 males and 11 females between 42 and 70 years of age, all of whom came from other institutions. The follow-up period ranged between a minimum of 4.6 and a maximum of 9.7 years. RESULTS: At the final follow-up, all patients were evaluated using the Merle D'Aubigne and Pastel model...

INTRODUCTION: Coxarthrosis is one of the most frequent and disabling pathologies.
20% of individuals over 60 years of age will develop symptomatic coxarthrosis and 10% of them will need a hip replacement; it is probably one of the orthopaedic procedures that most increases quality of life.When we recommend arthroplasty in clinical practice, patients often ask about the prognosis of their other hip. Will it deteriorate in the same way? Will it be necessary to replace it? When? The aim of the study is to determine if there is any variable or radiological sign that predicts the medium-term prognosis of the contralateral hip after total hip arthroplasty...

PURPOSE: Osteoarthritis (OA), osteoporosis, and bone fractures are frequent aging-related conditions. Regardless of the growing research interest in the effects of hip OA on femoral fracture risk, data about the region specificity of osteodensitometric and hip structure analysis (HSA) parameters of the proximal femora are lacking in aged postmenopausal women with hip OA compared to individuals with femoral neck fragility fracture. METHODS: This study included 76 postmenopausal women admitted for total hip arthroplasty due to non-traumatic femoral neck fracture (FN_Fx group, n = 39) and hip osteoarthritis (OA group, n = 37)...

INTRODUCTION: Osteonecrosis of the femoral head or avascular necrosis of the femoral head (HKN) is a complex disease that, without treatment, leads to infraction of the femoral head in most cases. In these cases, only replacement of the hip joint will help, although there is no clear recommendation of an arthroplasty type. In the last two decades, the treatment of primary and secondary coxarthrosis with short-shaft prostheses with different anchoring philosophies has increased. Since short-shaft fitting is a possible option especially in younger patients, the question arises about possible fittings of advanced HKN with these stem types, especially with metaphyseal anchorage...
