Intended Use

The StageOne™ Shoulder Cement Spacer Molds are intended to create a temporary hemi-shoulder replacement prosthesis as part of a two-stage revision procedure.

Device Story

Sterile, single-use silicone molds; used by surgeons in clinical settings to create temporary hemi-shoulder prostheses during two-stage revision procedures for septic shoulder infections. Surgeon fills mold with Refobacin® Bone Cement R; cement cures to form temporary implant; implant inserted into humeral medullary canal and glenoidal cavity after removal of infected hardware and debridement. Device acts as spacer to maintain joint space and deliver local antibiotics while systemic therapy addresses infection. Patient must adhere to activity restrictions due to cement material strength limitations. Temporary prosthesis must be explanted within 180 days and replaced with permanent hardware or alternative treatment.

Clinical Evidence

No clinical data provided. Substantial equivalence established via non-clinical bench testing, including biocompatibility evaluation, packaging testing, sterilization validation, fatigue performance testing, static performance testing, and antibiotic elution testing.

Technological Characteristics

Silicone molds; single-use; sterile. Used to shape Refobacin® Bone Cement R. Double sterile barrier packaging. No changes to design, materials, or sterilization method compared to predicate.

Indications for Use

Indicated for skeletally mature patients undergoing two-stage revision for septic process. Used to mold temporary hemi-shoulder prosthesis from Refobacin® Bone Cement R for insertion into humeral medullary canal and glenoidal cavity post-removal of existing implant and debridement. Used with systemic antibiotic therapy. Not for use >180 days. Contraindicated for patients unable to follow activity limitations due to mechanical limitations of bone cement.

Regulatory Classification

Identification

Polymethylmethacrylate (PMMA) bone cement is a device intended to be implanted that is made from methylmethacrylate, polymethylmethacrylate, esters of methacrylic acid, or copolymers containing polymethylmethacrylate and polystyrene. The device is intended for use in arthroplastic procedures of the hip, knee, and other joints for the fixation of polymer or metallic prosthetic implants to living bone.

Special Controls

*Classification.* Class II (special controls). The special control for this device is the FDA guidance document entitled “Class II Special Controls Guidance Document: Polymethylmethacrylate (PMMA) Bone Cement.”
