## Indications for use
StageOne™ Select Hip Cement Spacer Molds with stainless steel reinforcement stems, adapters and inserts are indicated for use to mold a temporary hemi-hip replacement for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary prosthesis is molded using Refobacin Bone Cement R, assembled and inserted into the femoral medullary canal and acetabular cavity following removal of the existing femoral and acetabular replacement implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The hemi-hip prosthesis made from the StageOne™ Select Cement Spacer Molds is not intended for use more than 180 days, at which time it must be explanted and permanent devices implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion, etc.). Due to the inherent mechanical limitations of the hemi-hip prosthesis material (Refobacin Bone Cement R), the temporary hemi-hip prosthesis is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.
