The wrist is one of the most complex joints in the human body, comprised of multiple bones and ligaments, and capable of performing a variety of movements. Proper wrist motion relies heavily on the interplay between the carpal bones of the hand and its ligamentous connections, and when that interplay is compromised hand function can be severely...

Brachytherapy (BT) is an essential component in the curative treatment of cervical cancer. With commercial BT implant devices, called applicators, the radioactive sources can only be positioned in fixed intracavitary channels or in a fixed array of interstitial needles. Patient-tailored BT applicators containing individualised needle channels...

Background: Despite over a century’s worth of technical improvements, the longterm survivability associated with orthopedic implants continues to fall short. In contrast to earlier designs, implant failure is no longer caused by structural failure of the implant itself. Rather, it results from the implant’s long-term detrimental effects on the...

Introduction <br/>An innovative, patient-specific, hip implant was developed for canine patients suffering from developmental hip dysplasia. In a first cohort study, the post-operative positions of the implants deviated with an average of 5 mm when compared to the pre-operatively planned positions. A novel augmented reality (AR) based intra...

The currently available treatments for inner ear disorders often involve systemic drug administration, leading to suboptimal drug concentrations and side effects. Cochlear implants offer a potential solution by providing localized and sustained drug delivery to the cochlea. While the mechanical characterization of both the implants and their...

The antibacterial biofunctionality of bone implants is essential for the prevention and treatment of implant-associated infections (IAI). In vitro co-culture models are utilized to assess this and study bacteria-host cell interactions at the implant interface, aiding our understanding of biomaterial and the immune response against IAI without...

Additively manufactured (AM) biodegradable porous iron-manganese (FeMn) alloys have recently been developed as promising bone-substituting biomaterials. However, their corrosion fatigue behavior has not yet been studied. Here, we present the first study on the corrosion fatigue behavior of an extrusion-based AM porous Fe35Mn alloy under...

Ultrasound is a promising technology to address challenges in drug delivery, including limited drug penetration across physiological barriers and ineffective targeting. Here we provide an overview of the significant advances made in recent years in overcoming technical and pharmacological barriers using ultrasound-assisted drug delivery to...

This study proposes a new concept for an on-demand drug releasing device intended for integration into additively manufactured (i.e., 3D printed) orthopedic implants. The system comprises a surface with conduits connected to a subsurface reservoir used for storage and on-demand release of antimicrobial agents, covered with a cap that prevents...

Hip replacement surgery, also termed total hip arthroplasty, is a surgical intervention intended to substitute a deteriorated or dysfunctional hip joint with an artificial prosthesis. This procedure is commonly indicated for individuals experiencing severe hip discomfort resulting from conditions like osteoarthritis, rheumatoid arthritis, hip...

Introduction<br/>Reverberation causes a reduced speech perception in cochlear implant (CI) users. Therefore, a dereverberation method was proposed based on the weighted prediction error (WPE) algorithm with input from a deep neural network. The speech intelligibility for normal and hearing-aided listeners is improved by cancelling the late...

The thumb finger is indispensable for an independent daily life. Implant replacement, which aims to restore joint mobility and functionality, is one of the surgical treatments for patients with osteoarthritis at the thumb-base. However, current designs and the biomechanical understanding of the thumb-base joint are inadequate. Small bone size,...

Achieving appropriate soft tissue tension around the hip joint is an important factor for achieving hip stability after Total Hip Arthroplasty (THA). Hip instability leads to dislocations, pain, and is a common reason for early revision surgery. The current soft tissue tension assessments available during surgery rely on experience, and...

Congenital heart disease (CHD) affects almost 1% of newborns. Right ventricular outflow tract (RVOT) CHD affects 20% of newborns and includes anomalies such as tetralogy of Fallot (TOF) with or without pulmonary atresia, transposition of the great vessels, and truncus arteriosus. All these anomalies require RVOT reconstruction. Prosthetic heart...
