What is it indicated for?
The Monkey Bars Pin to Bar External Fixation System is intended to be used in adult and pediatric patients (specifically, children and adolescents aged 2 through 21 years) for provisional fixation of open and/or unstable fractures in the lower and upper extremities and pelvis. It may also be used for temporary fixation of peri-articular or intra-articular fractures. Additionally, the device can be used on fractures where soft tissue injury or an infected fracture site may preclude the use of other fracture fixation treatments.
Indications for use as stated in the FDA summary.
