Depuy Stainless Steel Bone Screws- pre-1976
Not Found
No
The device description and intended use are purely mechanical, and there is no mention of AI, ML, image processing, or data analysis.
No.
Explanation: The device is described as an "ancillary fixation device" (a bone screw) used in surgery, which is a medical device for structural support rather than therapy (treatment of disease or disorder).
No
Explanation: The device is a bone screw used for fixation during orthopedic surgery, not for diagnosing medical conditions.
No
The device description clearly describes a physical bone screw made of titanium and cobaltchrome, with specific dimensions and features for surgical implantation. It is a hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
- Device Description: The DePuy Low Profile Bone Screw is a physical implant designed to be surgically placed inside the body to fix components in knee and hip replacements.
- Intended Use: Its intended use is as an "ancillary fixation device" during surgery, not for performing diagnostic tests on bodily samples.
The description clearly indicates a surgical implant, not a diagnostic test kit or instrument.
N/A
Intended Use / Indications for Use
The DePuy Low Profile Bone Screw is indicated for use as an ancillary fixation device to be used with tibial and acetabular components in total knee and hip arthroplasty.

Device Description
The DePuy Low Profile Bone Screws, manufactured in both titanium and cobaltchrome, are manufactured in eleven lengths (15, 20, 25, 40, 45, 50, 55, 60 and 65mm) with a 6.5mm major diameter. The head of the screw is designed with a "low profile" to allow the head to be placed below the surface of the device being fixed. An internal hex fitting in the head is used for instrument (a hex drive) insertion of the screw during surgery. The distal two-thirds of the screw is coarsely threaded while the proximal one-third is smooth with a polished satin finish. The screw has a distal flute to aid in insertion into cancellous bone.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
Identification. A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.(b)
Classification. Class II.

Depuy Stainless Steel Bone Screws- pre-1976
DEVICE DESCRIPTION AND INTENDED USE:
The DePuy Low Profile Bone Screws, manufactured in both titanium and cobaltchrome, are manufactured in eleven lengths (15, 20, 25, 40, 45, 50, 55, 60 and 65mm) with a 6.5mm major diameter. The head of the screw is designed with a "low profile" to allow the head to be placed below the surface of the device being fixed. An internal hex fitting in the head is used for instrument (a hex drive) insertion of the screw during surgery. The distal two-thirds of the screw is coarsely threaded while the proximal one-third is smooth with a polished satin finish. The screw has a distal flute to aid in insertion into cancellous bone. The DePuy Low Profile Bone Screw is indicated for use as an ancillary fixation device to be used with tibial and acetabular components in total knee and hip arthroplasty.
BASIS OF SUBSTANTIAL EQUIVALENCE:
Except for the larger major diameter, change in manufacturing material (from stainless steel to either titanium or cobalt-chrome alloys) and the restriction of the intended use to an ancillary fixation device to be used with tibial and acetabular components in total knee and hip arthroplasty, the DePuy Low Profile Bone Screws are substantially equivalent to the pre-1976 DePuy stainless steel bone screws indicated for general use in fracture fixation and bone reconstruction. All are manufactured in various lengths to accommodate patient bone structure and surgeon preference. All are designed with a distal flute to aid in insertion into cancellous bone. Based on the information provided in this premarket notfication, DePuy considers the DePuy Low Profile Bone Screws to be substantially equivalent to specified pre-1976 fixation screws.

Re: K970929 Low Profile Bone Screws Regulatory Class: II Product Code: HWC Dated: March 12, 1997 Received: March 13, 1997
Dear Ms. Foust:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). 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. Note that labeling or otherwise promoting a device for pedicular screw fixation/attachment would cause the device to be adulterated under 501(f)(1) of This device, if intended for use in pedicular screw the Act. fixation/attachment, would be found not substantially equivalent and would be a class III device under Section 513 (f) of the Act. Class III devices are required to have an approved premarket approval (PMA) application prior to marketing. Accordingly:
2
-
- The package insert must prominently state that the device is intended for the specific use(s) described in the enclosure only; and
-
- You may not label or in any way promote this device for w pedicular screw attachment to, or fixation of the cervical, thoracic or lumbar vertebral column. If this device is a screw with outer diameters of 3 mm - 10 mm
- and overall lengths of 10 mm 75 mm inclusively, the 乐 package insert must include the following statement, "WARNING: This device is not approved for screw attachment or fixation to the posterior elements (pedicles) of the cervical, thoracic, or lumbar spine." Any pedicular screw fixation/attachment to the cervical, thoracic or lumbar vertebral column of this device is considered investigational and may only be investigated as a significant risk device in accordance with the investigational device exemption (IDE) regulations under 21 CFR, Part 812. All users of the device for pedicular screw fixation/attachment must receive approval from their respective institutional review boards (IRBs) and the Food and Drug Administration (FDA) prior to conduct of the investigation.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), 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 895. ਸ substantially equivalent determination assumes compliance with the Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.
