Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Device(s) being tested: Interchangeably: Direct Socket TF; DS-TF; DS Trans-femoral.
The DS-TF is a trans-femoral (TF) set-up of the currently marketed trans-tibial version. It is not marketed in the USA and has not been registered with the FDA.
The comparator is the current socket the subject is using when enrolled in the study.
Subjects recruited: Minimum 50
Inclusion criteria:
50Kg\< body weight \< 160Kg Cognitive ability to understand all instructions and questionnaires in the study; Patients who have undergone a transfemoral amputation \> 1 year post amputation Older than 18 years Willing and able to participate in the study and follow the protocol Circular dimension of 40-65 cm at the crotch Residual limb length at least 20 cm from ischium to distal end Currently using a prosthetic liner Locking users that can successfully be fitted with Iceross® Transfemoral Locking, OR Seal-In users that can successfully be fitted with either Iceross Seal-In® X5 TF or Iceross Transfemoral Seal-In®
Exclusion criteria: 50Kg\> body weight \> 160Kg Users with cognitive impairment Patients who have undergone a transfemoral amputation \<1 year post amputation Younger than 18 years Not a prosthetic ambulator, uses only the prosthesis for cosmetic reasons Circular dimension of less than 40 cm or greater than 65 cm at the crotch Residual limb length less than 20 cm from ischium to distal end Currently not using a prosthetic liner
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
All investigational activities will be conducted at prosthetic out-patient clinics.
As stated above the primary endpoint is successful use rate, see Table 2, and the secondary endpoints are listed in the table from B-H in that respective order of significance. See previous chapter on objectives and hypothesis and Table 2 for rationale.
Drop-outs and withdrawals will not be replaced.
Equipment required for each subject:
* Pen/pencil
* Printed out instruments
* Investigational device: Materials for making DS-TF socket o Designated locking or seal-in liner to be fitted with the socket
Additionally, each LPI or LCI will have access to:
* Equipment for DS-TF socket manufacturing
* iPad with the Össur ProApp installed for data collection The equipment used does not require specific monitoring, maintenance or calibration procedures.
The purpose of the study is to evaluate in a cohort the time it takes to manufacture and delivery (lead time) of a definitive prosthesis (definition of finished prosthetic leg is, a prosthesis that is individually tailored and able to be used both indoors and outdoors, with the maximum weight on the patient equivalent to 160 kg). The existing prosthesis is to be evaluated as well as the new socket. The evaluation of function will take place at baseline, 6 weeks and 6 months after deliverance.
The following outcome instruments will be used:
• At all three study evaluation points; initial fitting, 6 wees and 6 months:
* OPUS (LEFS, CSD, CSS) https://www.sralab.org/rehabilitation-measures/orthotics-prosthetics-users-survey
* ProAMP (to test the current function with prosthesis)
* EQ-5D (for life quality)
* Socket Comfort Score (SCS)
* CLASS - socket fit
* Plus-M
* ABC
* TUG
Cost of fitting, to all parties, will be collected and reported. Whatever the outcome of the study will be, it will be very informative for healthcare systems, both payers and providers, and manufacturer of equipment for amputees.
The total time required to implement the full clinical investigation is expected to be approximately 26 months. Each individual subject is expected to participate in the clinical investigation for a minimum of 6 weeks, up to 6 months. The estimated time needed to include the required number (enrolment period) is 20 months.

Clinical need
Participants enrolled that require a new socket.
Direct Socket TF
The device is Class I, a low-risk product, and is a further development of a well-established technology. Össur Direct Socket (DS) technology has been on the market since 1996 (ICEX first generation) for the manufacture of leg prosthesis. This prosthetic socket for trans-femoral amputees (referred hereby to as DS-TF) has the same basic functional design as the Direct Socket (MSS) for trans-tibial amputees (referred hereby to as DS-TT) that is available on the market today in addition to the newly added silicon brim.
A prosthetic socket is a non-invasive, non-sterile, single user reusable device, which is used as part of prosthetic system. The aspect of the prosthesis that is in direct physical contact with the amputee is usually not the socket, to which a prosthesis is connected to, but the liner that serves as an interface between the amputee and the rest of the prosthesis. An amputee typically wears a prosthesis and thereby utilizes a socket, for up to 18 hours a day.
No clincal need
Participants enrolled that do not require a new socket
