About this study
Official title: Pilot for Dual Implant Versus Single Implant Distal End of Femur (pDISIDE Femur)
This research study is being conducted to examine the effect of two versus one fixation device for fixation of distal femur fractures.
- Conditions
- Femur Fracture
- Being tested
- Single Distal Femur Implant, Dual Distal Femur Implant
- Medical subject headings
- Femoral Fractures
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Single Distal Femur ImplantProcedure or surgery
Single implant constructs will be either a retrograde intramedullary nail with interlocking screws or a single plate and screw construct.
Dual Distal Femur ImplantProcedure or surgery
Dual implant constructs will either be an intramedullary nail with an additional plate and screw construct or dual (two plates in any orientation) plate and screw construct.
| Study group | Role | What they receive |
|---|---|---|
| Single Distal Femur Implant Group | Active comparator | Subjects will receive one of two types of implants for the distal femur fracture. The single implant will be either a plate and screws or a rod. The type of single implant used will be determined by the surgeon based on the characteristics of the fracture. Receives: Procedure: Single Distal Femur Implant |
| Dual Distal Femur Implant Group | Experimental | Subjects will receive two implants for fixation of the distal femur fracture. The dual implant will be either 2 plates with screws or a plate with screws and a rod. The type of dual implant used will be determined by the surgeon based on the characteristics of the fracture. Receives: Procedure: Dual Distal Femur Implant |

Questions about this trial
What is this clinical trial studying?
A study testing Single Distal Femur Implant and Dual Distal Femur Implant in people with Femur Fracture, run by Mayo Clinic at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 10 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of study-eligible subjects (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Mar 2026; AzTrials last refreshed its copy on 8 Nov 2026.
