ASTM F Flexural Fatigue Testing Metallic Bone Plates. After orthopedic reconstructive ASTM F Metallic Angled Orthopaedic Fracture Fixation Devices. Although ASTM F (Four Point Bend) test standard may seem very straight forward, there are specific guidelines you must follow to maintain. Metallic Bone Plates need to undergo several tests before gaining approval as internal fixation devices of the skeletal system. One standard, ASTM F

The user is cautioned to consider the appropriateness of the method in view of the devices being tested and their potential application. Therefore, the test method is not applicable for testing bone plates under ff382 that would approach or exceed the bending strength of the bone plate being tested.
Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F The convex surface, where accompanying bone screws will be inserted, should face downward, towards the support rollers.
Historical Version s – view previous versions of standard. The data generated from this test method can be used to adtm relative comparisons of different bone plate designs. When comparing test results of prototype devices and predicate devices, make sure the tests were conducted in a similar fashion, without major deviations or differences in test setup, the specimen, and method in which data was collected and analyzed.
Link to Active This link will always route to the current Active version of the standard. There are many steps a Test Engineer or Technician can take early in the testing stages to avoid the painful woes of mechanical testing.
Either way, there are appropriate occasions when the user may deviate from a test standard. The strength and stiffness of the plate allows the bone to heal while providing structural support.
In most instances, only a subset of the herein described test methods will be required. Instead, the user should only select test methods that are appropriate for a particular device design.
No other units of measurement are included in this standard. Have a question about conducting the test for this standard? This specification and test method establishes the consistent methods for classifying, and defining the geometric and performance characteristics of five types cloverleaf, cobra head, reconstruction, straight, and tubular of metallic bone plates used in the surgical internal fixation of the skeletal system.
There are instances when we test prototypes and new devices without an established asstm specification. Futhermore, it is f38 the intention of the standard to describe or specify specific designs for bone plates used in the surgical internal fixation of the skeletal system. Futhermore, it is not the intention of the standard to describe or specify specific designs for bone plates used in the surgical internal fixation of the skeletal system. By Engaged Expert Maciej Jakucki.
Perfect the test setup. TestResources has advanced experience in the biomedical field. Become familiar with the test standard in order to perform the test accurately.
Link to Active This link will always route to the current Active version of the standard. Rollers are available in various sizes for different size bone plates. This article is geared towards bone plate asgm within the medical device industry. Therefore, the method is not applicable for testing bone plates made from materials that exhibit non-linear elastic behavior.

The four point flexural bend fixture consists of two loading rollers near the center and two support rollers at the ends of the fixture. F suggests using rollers of equal diameters within the range of 6 to 12 mm.
Also presented here are catalogs of standard specifications for material, labeling, and handling requirements, aetm standard test methods for measuring performance related mechanical single cycle bend and bend fatigue characteristics determined to be important to the in vivo performance of bone plates.

Important Guidelines for ASTM F382 Bone Plate Testing
When working with the FDA or another regulatory body, one will have to justify their reason for deviating from a specification. However, it must be noted that the user is not obligated to astn using all of the described methods.
Active view current version of standard. This test method may be used to determine a fatigue life of the bone plate at either a specific maximum bending moment or over a range of maximum bending moment conditions.
ASTM F – 17 Standard Specification and Test Method for Metallic Bone Plates
Bone plates are used during orthopedic orthopaedic reconstructive surgery for alignment and fixation of bone segments. There are occasions when the test must deviate from the spec in order to successfully carry out the experiment. While on the subject of test setup, we should also discuss the use of rigid extension segments.
ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. Some specimens are unusual in shape, size and function. The standard establishes consistent methods to classify and define the geometric and performance characteristics of bone plates.

Abnormally shaped bone plates will obviously be much trickier to set up and test. Make an inquiry today. If the test data is for internal use, then one can deviate f3382 loosely.
