Design outcomes

Primary

MeasureTime frame
Main Objective: In patients undergoing surgical excision and endoprosthetic reconstruction of a lower extremity bone tumor, is there any difference in the effect of postoperative antibiotic regimens (24 hours vs. 5 days) on infection rate outcomes?;Secondary Objective: In patients surgically treated for bone tumors of the lower extremities followed by limb reconstruction using an endoprosthesis, what is the impact of the postoperative antibiotic regimen (24 hours vs. 5 days) on the development of antibiotic-related complications (ie: gastrointestinal infections, fungal infections, etc.) and on patient functional outcome and quality of life after one year? ;Primary end point(s): The primary study endpoint is the development of a deep surgical site infection (SSI) within 12 months following the initial surgery to treat a primary bone tumor of the lower extremities. ;Timepoint(s) of evaluation of this end point: Patients will be monitored regularly by the treating physician at 2 weeks, 4 weeks, 3 months, 6 months, 9 months, and 1 year.

Secondary

MeasureTime frame
Secondary end point(s): The secondary study endpoints include patients’ functional outcome and quality of life, as well as antibiotic-related complications.;Timepoint(s) of evaluation of this end point: 3 months, 6 months, 9 months, 1 year.
