About this study
Official title: Direct Skeletal Fixation of Prosthetic Limbs Following Trans- Femoral Amputation - Study of an Intraosseous Transcutaneous Amputation Prosthesis (ITAP)
Direct Skeletal Fixation of Prosthetic Limbs Following Trans-Femoral Amputation - Study of an Intraosseous Transcutaneous Amputation Prosthesis (ITAPTM).
Read the detailed description
The core ITAP™ design comprises of three discrete sections, the proximal section, which is the intramedullary stem secured into the medullary canal, the soft tissue integration flange and the transcutaneous component that passes through the skin. The device has been designed to be surgically implanted in a one stage procedure. In greater detail:
Intra-medullary stem - this component is designed to match the natural shape of the canal and is designed using the same principles established and used for the fixation of massive endo-prosthetic replacements. In certain cases a hydroxyapatite ceramic (CaPO4) coating is used, providing enhanced uncemented fixation. In other cases, depending on the geometry of the intramedullary canal, the stem can be fixed in place using acrylic bone cement.
- Conditions
- Traumatic Amputation of Lower Extremity
- Being tested

Questions about this trial
What is this clinical trial studying?
A study testing Direct skeletal fixation of ITAP to lower limb amputees. in people with Traumatic Amputation of Lower Extremity, run by Stryker Orthopaedics at 2 sites in United Kingdom.
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 13 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?
The record lists 2 sites in United Kingdom. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Adhesion check in the skin surrounding the ITAP (time frame: 12 month post surgery). The study lists 6 primary outcomes in all. 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 22 Oct 2018.
