Early Feasibility Study of the Percutaneous Osseointegrated Prosthesis (POP)
- Conditions
- Traumatic Amputee
- Interventions
- Device: Percutaneous Osseintegrated Prosthesis
- Registration Number
- NCT02720159
- Lead Sponsor
- Encore Medical, L.P.
- Brief Summary
The purpose of the clinical study is to characterize the efficacy and safety of a Percutaneous Osseointegrated Prosthesis (POP) device that can provide a satisfactory platform for direct skeletal attachment of prosthetic limbs, which includes a subdermal seal, thus allowing a proper biobarrier around the implant.
