Osteonecrosis

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

This study will evaluate the effectiveness of hyperbaric oxygen therapy (HBOT) on treating emerging indications (i.e., conditions that have shown to potentially benefit from HBOT) using the Multicenter Registry for Hyperbaric Oxygen Treatment. The study team aims to collect ongoing data on how well HBOT treats these emerging indications, and to add these data to the growing HBO Registry. The research team hypothesizes that HBOT will result in improvements of the condition of the various emerging indications.

The primary objective of this study is to determine whether the Hyperbaric Oxygen Therapy (HBOT) conducted under the Marx Protocol improves pain outcomes when combined with core decompression with autologous bone marrow aspirate concentrate to treat patients with femoral head avascular necrosis.

Any patient aged 14 or older up to 64 years of age with hip disease, resulting in loss of articular cartilage integrity on the femoral head (e.g., femoroacetabular impingement or other structural deformity), has failed conservative care, and is a candidate for surgical intervention to treat.

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 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 investigators aim to develop a prospective database in which patient demographics, surgical, dental, prosthetic and QOL parameters collected during consecutive visits within the framework of routine practice, are being registered for each oncological patient eligible for (immediate/delayed) fixed prosthodontic rehabilitation at time of oral cavity reconstruction
