Active clinical trials for "Prosthesis Failure"

The finger and fingertip are the most frequently amputated body parts, due to work-related incidents. Yet because of space, weight and cost constraints, prosthetic fingers and fingertips are heavy and bulky with limited active motion and sensation. Most are basic variations on the hook and claw. Lower limb prostheses have become extremely technologically advanced in their design and materials, and upper limbs lag behind in all of these areas. This is due to the complexity of the anatomy and function of the upper limb compared to the lower. There are no commercially available prostheses that offers direct sensory feedback and as such, rely on visual feedback from the wearer. The original PROLIMB study (PROLIMB I) used a Leap Motion Controller (LMC) to investigate the type of grasp adaptation that have been undertaken by patients during the rehabilitation process following amputation and compared this to similar data from healthy volunteers. PROLIMB I also looked at refining the tactile feedback system by investigating the sensation felt on amputation sites in order to feed this information into the haptic feedback system. The vision of the PROLIMB II project is to build on the work completed in PROLIMB I and develop and combine mechanistic models of hand motion and haptic sensing to deliver novel, affordable body-powered prosthetic fingertip digits with enhanced motion and sensation to address current clinical needs and support the quality of life of amputees. With collaboration from the University of Warwick (UoW) and University College London (UCL), Steeper Group and Naked Prosthetics the PROLIMB II study will aim to model, design, fabricate and validate a body-powered prosthetic fingertip digit with integrated sensory feedback. The University Hospital Coventry & Warwickshire (UHCW) will provide the clinical facility with which to assess the comfort, usability and acceptance of this prosthetic in the daily lives of patients with digit amputations. This project will be a proof of concept study with verification of the prosthetic in motion capture (gait) laboratories as well as the use of simple validation data collection over a longer period.

The implantation of artificial hip joints is one of the most frequently performed surgeries. Normally, patients are very satisfied with the results. The MobileLink hip prosthesis system is a CE marked medical device. This means the the safety and performance of the prosthesis ist approved. Aim of the study is to collect clinical data about the outcome of the MobileLink hip prosthesis systen under routine condition and the determine the satisfaction of the patients.

To analyze the short and long term postoperative clinical outcome and patient satisfaction of silicone gel-filled testicular implants.

This study is part of the clinical evaluation of SEBBIN silicone gel-filled testicular implants, included in the technical file of the device. The aim of the study is to gather additional data about the safety and effectiveness of the device.

This study titled "Prospective, Multicentre Study to Assess Performance of the MonoCer Acetabular Cup in Primary Total Hip Replacement" is a multi-centre prospective registry-nested cohort study, using AOANJRR's web-based data collection system integrated with Registry data collection, designed to assess the ten-year clinical outcome of the MonoCer Acetabular Cup in Primary Total Hip Replacement. The primary outcome measure is mortality and secondary measures are PROMs and complications.

The Intervention Will be All Ceramic Single-retainer Resin Bonded Fixed Partial Denture Using the Upper Canine as Abutment With Minimum Preparation on the Lingual Surface Within the Enamel Providing Maximum Area for the Retainer Bonding, to Replace the Upper Lateral Incisor and Will be Compared With the Control/Comparator Group Which is the All Ceramic Single-retainer RBFPD Using the Upper Central Incisor. The Participants in This Study Will be Recruited by the Researcher From the Clinic of Fixed Prosthodontics Department, Clinic of Orthodontics Department and Clinic of Diagnosis Department, Cairo University Without Any Financial or Non-financial Incentives.

The study concerns the technique of osseointegration that consists of inserting a titanium pin into the bone of the amputated limb. A removable external prosthesis will then be connected to the implant section that protrudes from the soft parts. The benefits of using an osseointegrated prosthesis are the improved sensory feedback (osseoperception) and absence of the socket. This leads to better anchoring of the prosthesis to the abutment, greater control of the prosthesis and the absence of heat, pain, and pressure sores. The osseointegrated prosthesis does not reduce the mobility of the limb and promotes good growth of bone and muscle mass. The aim of this study is to evaluate the stability of the osseointegrated implant in trans-femoral and trans-humeral amputees. The main outcome: quantitative evaluation (rotations, translation and MTPM) of the stability of the implant bone interface by Roentgen Stereo-photogrammetric Analysis (RSA) and follow-up. The secondary outcome: evaluation of the quality of life improvement in patients through clinical score and satisfaction survey.

The aim of this observational study is to collect clinical and radiological results of the new Plasmafit® Revision Structan® Hip Endoprosthesis Cup in a standard patient population and when used in routine clinical practice.

The main objective of the present prospective study is to evaluate the effectiveness of posterior zirconia FDPs after 14 years of function.
