Groups/Cohorts Assigned Interventions
VEPTR patients
Children treated with VEPTR Implants for severe spinal or thoracic deformities
Device: Microbiological analysis of retained VEPTR Implants
Implants have to be adapted every half a year, the retained implants during revision are analysed for biological colonization.

Detailed Description:
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.

Ages Eligible for Study:   1 Year to 30 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Children with severe spinal or throacic deformities treates with VEPTR-implants. In these patients the implant has to be revised every half a year due to grow and achieved correction.

Inclusion Criteria:

  • all patients admitted at the University Children's Hospital Basel in whom a VEPTR©-implant or parts of it will be removed.

Exclusion Criteria:

  • obvious contamination of an explanted component occurred in the operating room.
