AI/ML (Artificial Intelligence / Machine Learning)

No
The device description focuses on mechanical components and their function in surgical procedures, with no mention of software, algorithms, or data processing that would indicate AI/ML.

Therapeutic

Yes
The device is described as an adapter used in proximal femoral replacement procedures for oncology cases and limb salvage, which clearly indicates its therapeutic purpose in re-establishing anatomical structure and function.

Diagnostic

No

Explanation: The GMRS Adapter is described as a device intended to mate components of hip replacement systems for surgical procedures, specifically for proximal femoral replacement. It is a fabricated piece of titanium alloy, directly involved in the replacement of bone rather than in diagnosing a condition.

SaMD (Software as a Medical Device)

No

The device description clearly states the GMRS Adapter is a physical, two-piece design fabricated from titanium alloy, intended for surgical implantation. It is a hardware component, not software.

IVD (In Vitro Diagnostic)

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health.
Device Description and Intended Use: The description clearly states that the GMRS Adapter is a surgical implant used to connect different components of a hip replacement system. Its intended use is for proximal femoral replacement in surgical procedures.
Lack of Mention of Specimens or Analysis: There is no mention of the device interacting with or analyzing any biological specimens.

Therefore, the GMRS Adapter is a surgical implant, not an in vitro diagnostic device.

Overview

Intended Use / Indications for Use

The GMRS Adapter is intended to mate the Proximal Femoral Components and Femoral Bodies of the MRS or Proximal Femoral Body or Extension Pieces of the GMRS to the distal femoral stems of the Restoration™M Modular Hip System. The GMRS adapter is intended for use with the above-noted components in proximal femoral replacement indicated 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. Adequate bone stock must be present to allow the use of the Restoration™ Modular Distal Femoral Stems. Indications and contraindications of the GMRS Adapter when used with the Proximal Femoral Bodies of the MRS and GMRS, and the distal femoral stems of the Restoration™ Modular Hip System follow:

Indications
Proximal 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.

Device Description

The GMRS Adapter is a single use, two piece design consisting of the Adapter and the Adapter Locking Screw The GMRS Adapter is fabricated from titanium alloy (titanium -6 Aluminum-4 Vanadium) and is available in four sizes: standard, +10mm, +20mm, and +30mm. The proximal portion of the GMRS Adapter serves as the male portion of a taper lock that is assembled to the female taper in the distal end of the MRS or GMRS Proximal Femoral Component or Extension Pieces. The distal portion of the GMRS Adapter contains a female taper that accepts the male taper of the Restoration™ Modular Distal Femoral Stems. There are scribe marks on the GMRS Adapter to allow the surgeon to orient the amount of anteversion of the MRS or GMRS Proximal Femoral Component. The proximal portion of the male taper of the GMRS Adapter contains a female thread that serves two purposes: 1) to accept the GMRS Adapter Locking Screw after the taper lock has been engaged; and 2) for mating with a separation instrument should the surgeon need to reposition the adapter after it has been assembled to the Distal Stems of the Restoration™ Modular Total Hip System.

The GMRS Adapter Locking Screw is fabricated from titanium alloy (titanium- 6 Aluminum -4 Vanadium) and is available in four sizes that correspond to the sizes of the Adapter: standard; +10mm, +20mm, and +30mm. The GMRS Adapter Locking Screw is used to augment the taper lock of the GMRS Adapter into the Restoration™ Modular Distal Femoral Stems. The GMRS Adapter Locking Screw is packaged with the corresponding size GMRS Adapter.

Regulation Number and Section

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.

(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.

Indications

Proximal 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.

Contraindications

As related to Bone Tumors A.

Not all bone tumors may be treated successfully by segmental resection. Any condition that may have already resulted in either local or distant spread of the tumor may be a contraindication. Examples of such conditions include:

pathological fracture; .
. overt infection;
. inopportune placement of biopsy incision; and,
rapid disease progression beyond a respectable margin. .
C. As related to Failed Previous Prosthesis and Trauma
Any active or suspected latent infection in or about the hip joint. .
. Any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure, or complication in postoperative care.
Bone stock compromised by disease, infection, or prior implantation that cannot . provide adequate support and fixation of the prosthesis.

For the use of GMRS Adaper with the Distal Stems of the Restoration Modular Hip System, the following additional contraindication should be noted:

Inadequate bone stock to allow the use of a press fit stem .
