Active clinical trials for "Osteonecrosis"

A prospective study to determine how low bone mineral density and/or vertebral compression fractures associate with pain in adults with sickle cell disease

Medication-related osteonecrosis of the jaw (MRONJ) is a drug adverse reaction and there is no consensus for the treatment of MRONJ. The aim of this study is to evaluate the mucosal coverage using HAM after sequestrectomy in patients with stage-2 MRONJ.

Medication-related osteonecrosis of the jaw (MRONJ) occurs after taking bisphosphonates or targeted therapies. It leads to a significant decrease in quality of life with pain, eating and chewing disorders, and malnutrition. Current treatments are only partially effective. PENTO (pentoxifylline and tocopherol) has been shown to be effective in maxillary osteoradionecrosis. The objective of this study is to evaluate the proportion of bone recovery in patients receiving PENTO in MRONJ at 12 months.

This clinical study is a Post-Market Clinical Follow-Up (PMCF) measure and is aiming to compare the in-vivo wear behaviour of the Columbus® total knee prosthesis between the standard Cobalt Chromium (CoCr) and the multilayer coated so called "Advanced Surface" (AS) of the same implant. The clinical investigation is designed as a International, prospective, longterm non-interventional study in order to gain clinical data of many patients within the routine clinical application of the investigational device.

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.

This pilot trial studies the differentiation of bone sarcomas and osteomyelitis with ferumoxytol-enhanced magnetic resonance imaging (MRI). Imaging procedures that allow doctors to more accurately differentiate between malignant bone sarcomas and osteomyelitis may help in diagnosing patients correctly and may result in more timely treatment.

The objective of this study is to collect and evaluate long-term clinical and radiographic outcomes data in order to better understand the safety and performance of the shoulder arthroplasty over time. This study will follow subjects long-term for a minimum of 10-years, without an early-term restriction on the amount of time they will be followed.

A prospective, single-arm, intervention study of oral alendronate in adults with sickle cell disease and hip osteonecrosis

This is a multicenter, retrospective and prospective, non-controlled post market surveillance study. The objectives of this study are to confirm safety, performance and clinical benefits of the T.E.S.S.® Version 3 Anatomic and Reverse Modular Total shoulder prosthesis and its instrumentation.

The goal of the project is to evaluate osteonecrosis before and after decompression surgery with ferumoxytol-enhanced MRI.
