<b>Introduction:</b> Transfemoral amputation results in a prosthesis<span "=""> </span>which bears weight on the ischium. Gait disturbance,<span "=""> </span>lack of an end-bearing<span "=""> </span><span "="">stump and discomfort in the groin from the socket even while sitting, are important issues. <b>Methods:</b> This is a pilot report of an ongoing randomized blind clinical trial of a new intramedullary implant post transfemoral amputation. Here</span>, we describe<span "=""> </span>a single case illustrating the surgical technique and clinical outcome of a dysfunctional post-traumatic transfemoral amputation addressed with this implant.<span "=""> </span>Clinical gait analysis, SF-12 and VAS were assessed pre- and post-intervention <span "="">at 6 months of follow-up. <b>Results:</b> An improved stump control is accomplished by means of myoplasty and myodesis through an end-cap.
