Filter by:Avascular necrosis of the femoral head (AVN) is a progressive pathological process resulting from disruption of blood supply to the femoral head and elevation of intraosseous pressure. total hip arthroplasty is frequently the only durable option for pain relief and restoration of function. this is a single armed study to be done from July 2023 till January 2024, the total number of patients anticipated is 10, total joints treated around 20, The procedure includes core decompression with autologous bone marrow derived mononuclear cell injection inside the femoral head using local anesthesia ultrasound and fluoroscopy guided without drilling.
This Post Market Clinical Follow-Up (PMCF) study to evaluate the performance and safety of the cemented TrendHip® stem in a prospective follow-up study with patients who underwent a hip arthroplasty with the investigational product (representative of usual clinical practice), at two follow-up examinations
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.
The study is designed as a prospective, non-interventional multicentre cohort study. The product under Investigation will be used in Routine clinical practice and according to the authorized Instructions for Use (IfU). Aim of this observational study is to collect clinical and radiological results of the CoreHip® endoprosthesis system in a Standard Patient Population and when used in Routine clinical practice.
Methods to reduce the revision rate of total hip arthroplasties (THAs) because of wear-related issues are important to examine, particularly because younger patients have a disproportionately high risk of revision. The investigators hoped to follow up patients and see if long-term Harris hip scores and WOMAC scores better in younger patients with a ceramic-on-ceramic (COC) THA compared with those with a ceramic-on-highly-cross-linked polyethylene (COP) THA.
The purpose of this study is to determine if prolonged administration of low-dose aspirin will prevent the progression of early-stage osteonecrosis of the femoral head and may even reduce the extent of involvement of the femoral head by the necrotic process The design is intended to be parallel group where a total of 114 patients will be randomized in a 1:1 ratio to the treatment (ASA) and the control (Placebo) arms.
The purposes of the study is to evaluate the safety and efficacy of human umbilical cord mesenchymal stem cells (hUC-MSC) in treating osteonecrosis of femoral head patients.
The investigators,according to the eligibility criteria,plane to choose 80 elderly anticipates who will undergo selective hip replacement surgery.This participants will be randomly divided into 2 groups:light anesthesia depth group(L Group) and deep anesthesia depth group (D Group).Before anesthesia induction,each participant will be given lumbar plexus and sciatic nerve block in order to control pain of interoperative and postoperative.During operation period,the L Group will be kept in light anesthesia depth(BIS:50-60),while the D group will be kept in deep anesthesia depth(BIS:35-45)--The BIS values in the range of 30-60 have been recommended in general anesthesia.After operation,a PCIA(patient controlled intravenous analgesia) analgesia pump will be given to each participant to control postoperative pain. The investigator will evaluate the mental state of participant with MMSE(mini-mental state examination) before surgery and review each participant with a CAM-CR for 3 days after surgery to assess the situation of postoperation delirium.intraoperative awareness,postoperative pain will also be investigated in postoperative days 1, 2, 3.
To confirm 1) whether, compared with core decompression alone, core decompression with porous tantalum rod implantation improves the hip joint function of patients with avascular necrosis of the femoral head after femoral neck fracture surgery, 2) whether porous tantalum rod shows favorable biocompatibility with the human body, and 3) whether this treatment method is feasible for treating avascular necrosis of the femoral head after femoral neck fracture surgery.
In this Post Market Clinical Follow-up Study (PMCF Study), the short-term clinical and radiological results of the cementless Excia T® prosthesis in routine clinical use shall be assessed and the migration taking place in the first 24 months evaluated.
