The Stryker Global Modular Replacement System, Modular Replacement System and Modular Rotating Hinge Knee Component are sterile, single-use devices intended for use in situations where there is a need for replacement of bone due to radical bone loss. This loss can be related to oncology, trauma or failed previous prosthesis. Specific Indications for Use are listed below.
Indications for the MRS Stems and Intercalary Stems (presented in K952970):
- This device is intended for use in patients requiring extensive reconstruction of the femur . and/or proximal tibia, including the hip or knee joint, resulting from extensive bone loss. Tumor resection for skeletal lesions (Oncology patients where radical bone resection and replacement may be required), revision surgery for failed arthroplasty, and acute trauma are the primary causes of extensive bone loss. These prostheses are intended for use with bone cement.
- The Intercalary System is intended for use in situations arising from femoral mid-shaft tumor resection, or for prosthetic knee fusion.
Indications for the Global Modular Replacement System (presented in K023087):
- Femoral and/or proximal tibial replacement and total femoral replacement in Oncology cases where radical resection and replacement of bone is required, and in limb salvage procedures where radical resection and replacement of the bone is required. Limb salvage procedures would include surgical intervention for severe trauma, failed previous prosthesis, and/or Oncology indications.
Indications for the GMRS Anteverted Proximal Femoral Component (presented in K032581):
- Femoral replacement in Oncology cases where radical resection and replacement of bone is required, and in limb salvage procedures where radical resection and replacement of bone is required. Limb salvage procedures would include surgical intervention for severe trauma, failed previous prosthesis, and/or Oncology indications. This component may also be used with the Distal Femoral segment components of the GMRS in total femoral replacement.
Indications for the Global Modular Replacement System Press Fit Stems with HA Coating (presented in K022403, and K031217):
Proximal femoral reconstruction secondary to:
o Trauma
o Failed previous prosthesis
o Tumor resection
Indications for the Modular Replacement System Cemented Stems (presented in K040749):
Femoral and/or proximal tibial replacement due to:
o Trauma
o Failed previous prosthesis
o Tumor resection
Indications for the Modular Rotating Hinge Knee System (presented in K002552):
- The Modular Rotating Hinge Knee System is intended for use with bone cement in cases where there is destruction of the joint surfaces, with or without significant bone deformity; the cruciate and/or collateral ligaments do not stabilize the knee joint; the ligaments are inadequate and/or the musculature is weak; and revision of a failed previous prosthesis where there is instability, with or without bone loss or inadequate soft tissue. Expanded indications include for use with bone cement in situations where there is extensive bone loss, including limb salvage procedures for severe trauma, failed previous prosthesis, and/or Oncology indications.
The Global Modular Replacement System (GMRS) is comprised of a number of components that are intended to be used in conjunction with each other, or in conjunction with components of the Modular Replacement System (MRS) or the Modular Rotating Hinge Knee System (MRH). The Modular Rotating Hinge Knee System is a tricompartmental knee system. The system consists of a stemmed femoral component and a stemmed tibial bearing component connected by a set of bushings and an axle. The MRH Tibial Rotating component is a part of the MRH system and mates with the GMRS Standard Proximal Tibia. These devices are intended to be used in clinical situations where there is radical bone loss of the femur and/or proximal tibia. This radical bone loss can be related to oncology (tumor), trauma or failed previous prosthesis.
The provided FDA 510(k) clearance letter and summary for the Stryker Orthopaedics Global Modular Replacement System, Modular Replacement System, and Modular Rotating Hinge Knee Component does not contain information regarding acceptance criteria or a study proving the device meets specific performance criteria.
This document is a clearance letter indicating a determination of "substantial equivalence" to previously marketed predicate devices. It does not present novel performance data or studies against pre-defined acceptance criteria.
The key statements from the document that confirm this are:
- "Non-Clinical Testing: Non-Clinical testing was not required as a basis for substantial equivalence." (Page 8)
- "Clinical Testing: Clinical testing was not required as a basis for substantial equivalence." (Page 8)
The submission focuses on adding a contraindication to the labeling, updating MRI Safety information, and making clerical updates to the Instructions for Use (IFUs). These changes do not necessitate new performance studies for substantial equivalence.
Therefore, I cannot populate the requested table or answer the specific questions about acceptance criteria and studies because the provided document explicitly states that such testing was not required for this particular 510(k) submission.
§ 888.3350 Hip joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.
