Filter by:Osteonecrosis of the femoral head (ONFH) is a debilitating musculoskeletal disease that is characterized by localized death of bone cells and associated cellular elements within the subchondral bone. If it progresses, it results in the collapse of the femoral head (ball part of the hip) giving rise to secondary arthritis. This condition is associated with marked pain and loss of function, often necessitating a joint replacement. Due to the relatively young age of onset of ONFH (often in 20s and 30s), there is great interest in utilizing joint-preserving procedures prior to the need for joint replacement. Joint-preserving procedures include core decompression (CD) with and without bone grafts or cells, vascularized and non-vascularized bone grafting, as well as osteotomies. Inconsistent results for each of these procedures have been reported and there are no Clinical Practice Guidelines or medical community consensus opinions regarding the treatment of early-stage ONFH. The hypothesis to be tested is "Participants who have early-stage ONFH undergoing CD augmented with autogenous bone marrow aspirate concentrate will have better clinical and radiological outcomes than CD alone." This multi-center randomized controlled trial for early-stage ONFH is prospective and controlled for participant stage (only early-stage pre-collapse individuals) and surgical technique. Participants will be evaluated as per routine surgical follow-up, and at 6 months (telemedicine), 1- and 2- years using radiographs, MRIs, and questionnaires. This project will also explore the scientific basis for success vs. failure in individuals who have osteonecrosis, and have different demographics and bone marrow aspirate cell profiles.
Kinesiotaping is increasingly being used as a complement to musculoskeletal pain management. This study aimed to evaluate the immediate clinical efficacy of kinesiotaping on pain and pain-related symptoms of Legg-Calvé-Perthes Disease (LCPD).
A total of 250 total hip arthroplasties (THA) are performed at the Bezirkskrankenhaus St. Johann. In a majority of those, implants from the company Falcon Medical (Austria) are used. Those implants are undergoing constant development and improvement. To guarantee their clinical performance, this clinical study is evaluating safety and efficacy of all implants produced by Falcon Medical. The purpose of this study is to evaluate the effcacy and safety of implants produced and distributed by Falcon Medical. All patients with primary THA and usage of a Falcon Medical implant are included. The outcome measures include intra-operative complications, early post-operative complications, revision for any cause and patient reported outcome (WOMAC questionnaire). All data is prospectively collected in a standardized fashion.
The purpose of this study is to assess the clinical and x-ray results of patients who are treated with core decompression of the hip and the injection of a bone marrow concentrate and the use of the Bone Graft Substitute Genex®.
Calvé-Legg-Perthes disease (CLP) is a hip disease in children whose femoral head becomes completely or partially necrotic. The disease is most common in five-six years of age. The femoral head is gradually deformed during the active stages of the disease (5-7 years). By healing, the hip joint shape will vary from an approximately normal joint to pronounced changes, the hip joint will be irregular. Such a hip joint is available for osteoarthritis. The purpose of this study is to map the function of the hip, the patient's quality of life and especially the risk factors that affect the outcome of the previous CLP. A nationwide prospective study of CLP was conducted between 1996 and 2000. All children with newly diagnosed Perthes disease (425) were registered. The current study will follow up all these patients with an average follow-up of 20 years. Radiological endpoints are evidence of hip osteoarthritis. Patient-reported outcomes (PROMS) should illuminate the function of the hip and quality of life.
The incidence of Legg-Calvé-Perthes disease (LCPD) ranges from 0.4/100,000 to 29.0/100,000 children <15 years of age. There is significant variability in incidence within racial groups and is frequently higher in lower socioeconomic classes. The typical age at presentation ranges from 4 to 8 years (average 6.5 years).The optimal treatment goal in Legg-Calvé-Perthes disease (LCPD) is to obtain a spherical femoral head with good congruency to prevent or delay the onset of osteoarthritis after skeletal maturity. There is agreement that patients younger than 5years with a good remodeling capacity have a particularly excellent prognosis, irrespective of treatment.
Patient oriented clinical outcomes have increased in use and popularity and provide a comprehensive assessment of the level of symptoms and function experienced by a patient. Though several measures have been developed and shown to be valid, reliable, and responsive in adults, such efforts have only been rarely undertaken in pediatric populations. Specifically, there has been no validation of the predominant adult hip specific outcome measures, such as the WOMAC and Oxford-12, in children and adolescents. Prior to using such measures in pediatric patients, it is necessary to establish the psychometric properties of these measurements in this population. The objective of this study is to determine the reliability and validity of the WOMAC hip scores in a pediatric population, between five and nineteen years of age, with Perthes disease. The results of this study will accomplish the above goal, thereby allowing either for widespread use of these measures in pediatric hip disorders or emphasizing the necessity for development of a pediatric hip specific outcome measure.
In this study, the aim is to identify the modifications responsible for aseptic osteonecrosis of the femoral head and its structural evolution by the association of the micro scanner analysis and Raman spectrometry performed on the femoral heads removed during hip replacements. The study of femoral heads will allow the analysis of bone tissue at two different scales, both correlated with the biomechanical properties of the bone. Also, the association with preliminary MRI analysis will provide pathogenic explanations correlated to these modifications.
Background: Varus derotation osteotomy (VDRO) is one of the most popular surgical treatments for Legg-Calvé-Perthes disease yet its long term results have not been assessed. Our purpose was to determine the long term clinical and radiographic outcomes of these patients. Methods: Forty patients (43 hips) who had undergone VDRO for LCPD who participated in a long term follow-up study a decade ago were approached for the present study. All patients were treated in our institution during 1959 to 1983 with proximal VDRO. The patients were invited to for a medical interview and a physical examination. They were also asked to fill out questionnaires and to provide or undergo a standing anteroposterior (AP) pelvic and a lateral hip radiographs during the visit. Patients were asked to self-grade their hip pain as none, mild, moderate or severe and to grade their back pain using the Visual Analogue Scale (VAS) between 0-10. Details regarding daily function, physical activity, work status and family history were obtained. All participants completed the Harris Hip Score (HHS) with a maximum score of 100 and the Short Form-36 which is composed of 8 sections and has a maximum score of 100. The physical examination included an assessment of the hip range of motion, leg length discrepancy and the presence of a Trendelenburg sign. Radiographic parameters evaluated were the Tonnis grade (with a score between 0-3), head size ratio, and the center-edge (CE) angle.
