Filter by:Numerous studies describing surgical treatments to preserve hip replacements has several controversies and none of these procedures are universally accepted nor have compelling evidence for osteonecrosis of the femoral head (ONFH). With developing a newly approach osteonecrotic device surgical procedure to support the regeneration of necrotic bone and articular cartilage in vivo, this will be the first randomized-controlled feasibility study to determine its safety in ONFH patients.
This study is a Post Market Clinical Follow up study to fulfil the post market surveillance obligations according to Medical Device Directive and European Medical Device Vigilance System (MEDDEV) 2.12-2. The data collected from this study will serve the purpose of confirming safety and performance of the Avenir Müller Hip Stem.
This study is a Post Market Clinical Follow up study to fulfil the post market surveillance obligations according to Medical Device Directive and European Medical Device Vigilance System (MEDDEV) 2.12-2. The data collected from this study will serve the purpose of confirming safety and performance of the Zimmer Stafit Acetabular System.
The prospective, multicentric, observational study has the aims to monitor the performance of the MOTO medial unicompartmental knee system in the treatment of patients with knee disease requiring a UKA. 150 patients will be recruited in 18 months and will be reviewed until 5 years follow-up visit after surgery. The primary objective of the study is to evaluate the prosthesis survival at 5 years.
The investigators suppose that the impact of bisphosphonate therapy is beneficial on the bone during the growth period with few adverse events.
Surgical reconstruction to restore oral function and aesthetics after major ablative surgery in the oral cavity forms a challenge to maxillofacial surgeons, and greatly impacts patient' quality of life (QOL). The "Oncological-bridge (O-bridge®)" protocol, which offers (immediate/delayed) fixed prosthetic rehabilitation in a minimum of sessions and a strongly reduced two-week treatment time.
This study aims to evaluate the effect of bone marrow concentration on avascular necrosis of femur head by comparing clinical and imaging outcomes between patients receiving core decompression surgery with intraoperative bone marrow concentration and those receiving core decompression surgery only.
1. The course of AVN between Initial diagnosis and total hip replacement (THA) is analysed. The impact of early interventions versus conservative therapy in AVN before THA will be evaluated. 2. The short and long term outcomes of AVN patients undergoing THA with respect to complications, reoperations and quality of life are investigated. Potential risk factors for adverse outcomes will be investigated.
Participants who choose to participate in this study, will either have their tendon repaired to tendon, so-called tenotomy repair, or tendon repaired to bone, so-called peel repair.
One of the most serious sequelae of femoral neck fractures (FNFs) is avascular necrosis (AVN) and nonunion, and this translates to a significant morbidity and mortality. This study was conducted to determine the relationship between the etiologies and management of FNFs in our institution and its relationship to the development of AVN or nonunion.
