Read the detailed description
The goal of this observational study is to assess the safety and performance of the CE-marked "Biphasic Plate Distal Femur" during standard of care. The study is conducted as a retrospective and prospective multicenter case series. Eligible patients are those with fractures of the distal femur who are treated with the Biphasic Plate DF according to the Instruction for Use (IFU). The patient will be followed-up until healing or up to 12 months, whichever comes first.
To assess the safety and performance following data is collected:
- incidents of AEs/SAEs occurring in the affected lower extremity/extremities
- Bone healing assessed by a surgeon
- Weightbearing and function
- Patients' quality of life and pain level
- Conditions
- Distal Femur Fracture, Periprosthetic Fractures, Intra-Articular Fractures, Supracondylar Fracture
- Keywords
- Biphasic Plate DF, Distal Femur Fracture, Femur Fracture, Periprosthetic Fractures, Intra-Articular Fractures
- Medical subject headings
- Femoral Fractures, Distal, Periprosthetic Fractures, Intra-Articular Fractures, Femoral Fractures
What is being measured
The primary outcome is the main question the study is designed to answer.
Occurrence of AEs/SAEs in the affected lower extremity/extremities
The primary outcome measure is the occurrence of AEs/SAEs in the affected lower extremity/extremities that are deemed related, probably related, or possibly related to the surgical procedure or the Biphasic Plate DF
Measured: until clinically healed or up to 12 months
Secondary outcomes (2)
Bone Healing
Radiographic bone healing assessment using the modified Radiographic Union Scale for Tibia (mRUST) Score (1: Callus absent, visible fracture line, 2: Callus present, visible fracture line, 3: Callus bridging, visible fracture line, 4: Callus remodeled, invisible fracture line)
Bone healing as assessed by the surgeon
Measured: until clinically healed or up to 12 months
Patient-reported outcome measures
Quality of life questionaire Pain NRS (0-10) upon weightbearing
Measured: until clinically healed or up to 12 months

Questions about this trial
What is this clinical trial studying?
An observational study of Distal Femur Fracture and Periprosthetic Fractures, run by 41medical AG at 5 sites in 2 countries.
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 9 inclusion and 3 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 9 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Switzerland, Germany. 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?
Occurrence of AEs/SAEs in the affected lower extremity/extremities (time frame: until clinically healed or up to 12 months). 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 9 Sep 2026.
