## Indications for use
Hip Spacer Molds Hip Spacer Molds with stainless-steel reinforcement stems, centralizers and Hip Head Inserts are indicated for use to mold a temporary hemi-hip spacer for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary hemi-hip spacer is molded using Cemex Genta LV, and inserted into femoral medullary canal and acetabular cavity following removal of the existing femoral and acetabular implants and debridement. The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection). The temporary hemi-hip spacer made from Hip 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 temporary hemi-hip spacer material (Cemex Genta LV) the temporary hemi-hip spacers is only indicated for patients who will consistently use traditional mobility assist devices (e.g., crutches, walkers) throughout the implant period. Knee Spacer Molds Femoral Knee Spacer Molds and Tibial Knee Spacer Molds are indicated for use to mold a temporary total knee replacement (TKR) for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary prosthesis is molded using Cemex Genta LV and inserted into the joint space following removal of the existing total knee replacement implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection). The temporary total knee spacer made from the Femoral Knee Spacer Molds and Tibial Knee 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 temporary total knee spacer material (Cemex Genta LV), the temporary total knee spacer is only indicated for patients who will consistently use traditional mobility devices (e.g., crutches, walkers) throughout the implant period. Shoulder Spacer Molds Shoulder Spacer Molds with stainless-steel reinforcement stems, centralizers and Shoulder Head Inserts are indicated for use to mold a temporary hemi-shoulder spacer for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary hemi-shoulder spacer is molded using Cemex Genta LV, and inserted into femoral medullary canal and acetabular cavity following removal of the existing femoral and acetabular implants and debridement. The device is intended for use in conjunction with systemic antibiotic therapy (standard treatment approach to an infection). The temporary hemi-shoulder spacer made from Shoulder 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 hemi-shoulder prothesis material (Cemex Genta LV) the temporary hemi-shoulder prothesis is only indicated for patients who will consistently follow activity limitations throughout the implant period.
