Study summary

The purpose of this prospective study is to confirm safety and performance of the FastFrame External Fixation System and corresponding instrumentation.

Read the detailed description

Study Title: FastFrame™ External Fixation System Post-Market Clinical Follow-Up Study (Knee Spanning Kit and Damage Control Kit)

Sponsor: Zimmer Biomet

Study Design: Prospective enrollment, prospective follow-up, single cohort study

Clinical Phase: Postmarket

Number of Sites: Up to three sites

Study Duration per Subject: Subjects will be enrolled in the study until the time of exchange of their FastFrame Kit to another device. Typically, this exchange occurs 2-4 weeks after injury.

Primary Objective: The objective of this observational, prospective study is to confirm safety and performance of the FastFrame External Fixation System and corresponding instrumentation.

Primary Endpoint: Frequency and incidence of device-related adverse events and device deficiencies before the FastFrame External Fixation System is exchanged by another device (i.e. plates, screws, etc.).

Secondary Endpoint: Adverse events that occur between application of the FastFrame External Fixation System and exchange with another device that do not fall within the primary endpoint.

Inclusion criteria

  • Patient must be 18 years of age or older
  • Patient must be treated with either the Knee Spanning or Damage Control FastFrame External Fixation System according to the European Economic Area (EEA) indications*

EEA Indications (a subset of the cleared US indications):

The FastFrame External Fixation System - Knee Spanning Kit is indicated for use in treatment of long bone (distal femur, proximal tibia) fractures. Specifically, the system is intended for temporary stabilization of open or closed fractures about the knee, typically in the context of polytrauma or where open or alternative closed treatment is undesirable or otherwise .

The FastFrame External Fixation System - Damage Control Kit is indicated for use in treatment of mid-shaft long bone (femur, tibia) fractures. Specifically, the system is intended for temporary stabilization of open or closed fractures of the femur and tibia, typically in the context of polytrauma or where open or alternative closed treatment is undesirable or otherwise contraindicated.

Exclusion criteria

Exclusion Criteria:

  • Patient has an active or suspected infection
  • Patient has conditions that limit their ability and/or willingness to follow instructions during the healing process
  • Patient has inadequate skin, bone, or neurovascular status
  • Patient is a prisoner
  • Patient is pregnant and/or breastfeeding
  • Patient is a known current alcohol and/or drug abuser in the opinion of the Investigator
  • Patient has a mental or neurologic condition that will not allow for proper and/or participation in follow-up program in the opinion of the Investigator
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Adverse events

Collected over Per the protocol, International Organization for Standardization (ISO) definitions were followed for adverse event data collection. All adverse events were captured for subjects enrolled through 2 - 4 weeks follow-up or study completion (including lost to follow-up), whichever came first.. Non-serious events are listed at a 0% frequency threshold.
