Early Feasibility Study of the Percutaneous Osseointegrated Prosthesis (POP)

Not Applicable
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.
