This device is intended for use in patients requiring reconstruction of the proximal humerus due to extensive bone loss as a result of tumor resection secondary to primary or metastatic skeletal lesions. This device is intended for use with bone cement. This is the same intended use as the predicate device in premarket notification K954559. ## Device Story Modular Replacement System (MRS) Humeral Stems are orthopedic implants used for proximal humerus reconstruction following tumor resection. Subject device is a line extension of existing MRS Humeral Stems, differing by the absence of a porous coated body segment. Device is intended for use with bone cement. Stems are available in the same diameters and lengths as the predicate porous-coated versions. Used by surgeons in clinical settings to restore skeletal structure in patients with primary or metastatic bone lesions. ## Clinical Evidence No clinical data provided; bench testing only. ## Technological Characteristics Metallic humeral prosthesis; uncemented design (intended for use with bone cement); line extension of existing MRS Humeral Stems; lacks porous coating present on predicate. ## Regulatory Identification A shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis is a device made of alloys, such as cobalt-chromium-molybdenum. It has an intramedullary stem and is intended to be implanted to replace the articular surface of the proximal end of the humerus and to be fixed without bone cement (§ 888.3027). This device is not intended for biological fixation. ## Predicate Devices - MRS Humeral Stems ([K954559](/device/K954559.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
