Spinal and thoracic deformities in children can be treated with vertical expandable prosthetic titanium ribs (VEPTR©, Synthes GmbH®) to stimulate thoracic and spinal growth. With these implants children's symptoms and conditions can be slowed, halted or even reversed. Because of the dynamic character of the deformity and the growth of the children, the implants have to be lengthened about every half a year. With each operation there is a small risk of infection, which might increase with number of previous surgeries. Implant associated infections are often not clinical apparent and only found in microbiological analysis. To objectify the infection rate, identify potential precursors of infections and the relevance of asymptomatic infections in children with these implants a prospective study is conducted.

Primary Objective: To evaluate the use of unilateral or bilateral VEPTR devices, with or without expansion thoracoplasty, for preventing further progression of the Cobb angle, allowing for...
The investigators aim to determine the cause of failure of orthopaedic implants using multi-disciplinary analysis of data from patients who have undergone revision.
The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by one and two implants and the mandibular fixed prosthesis retained by four implants, base...
Peri-implant infections are severe complications after internal fracture fixation surgery. Detection of causative agents of orthopedic implant-associated infections (OIAI) is demanding. Se...
This study concerns patients having had an infection on their prosthesis (hip, knee,..) and for whom a 2-step exchange of prosthesis has been done. A 2-step exchange consists in explantat...
To quantify the rate of maintenance interventions of mandibular prostheses: complete dentures and overdentures retained by two implants, with either internal hex or external hex connections.
In the last decade, several studies have reported that short implants achieve excellent results with a 2-stage technique. According to the literature, short dental implants have often been used for th...
Comparison of Cemented vs Screw-Retained, Customized Computer-Aided Design/Computer-Assisted Manufacture Zirconia Abutments for Esthetically Located Single-Tooth Implants: A 10-Year Randomized Prospective Study.
To compare the clinical outcomes of screw-retained vs cemented single crowns supported by customized zirconia abutments on implants.
Endoscopic procedures are vital to gastrointestinal disease diagnosis and management, but risk infection transmission. In Australia, endoscopes undergo monthly-to-quarterly microbiological testing, to...
Implant-retained mandibular overdentures are a proven treatment modality for edentulous patients. Low-profile stud attachments may allow divergence between the abutments up to 40 degrees. The purpose ...
A non-invasive assessment of the stability of tissue-embedded prosthetic devices such as dental implants.
A placenta that fails to be expelled after BIRTH of the FETUS. A PLACENTA is retained when the UTERUS fails to contract after the delivery of its content, or when the placenta is abnormally attached to the MYOMETRIUM.
Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
Implants constructed of materials designed to be absorbed by the body without producing an immune response. They are usually composed of plastics and are frequently used in orthopedics and orthodontics.
Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
