The summary describes a resorbable bone screw and its mechanical testing, with no mention of AI or ML.
Yes
Healing ankle fractures, metatarsal fusions, and metatarsal osteotomies is a therapeutic intervention.
No
The device description and intended use indicate it is a bone screw used for surgical fixation in treating ankle fractures and metatarsal conditions, not for diagnosing them. The performance studies also focus on mechanical testing and healing effectiveness, not diagnostic capabilities.
No
The device description explicitly states the screws are made of a resorbable copolymer, indicating a physical hardware component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens from the human body. The description clearly states the device is a "Bone Screw" intended for surgical implantation to treat bone fractures and deformities. It is a physical implant, not a tool for analyzing biological samples.
- The intended use is for surgical fixation. The indications for use are specific surgical procedures (ankle fractures, metatarsal fusions, metatarsal osteotomies).
- The device description is of a physical implant. It describes the material and form of the screw.
- The performance studies are mechanical testing and animal model studies. These are relevant to the structural integrity and biological compatibility of an implant, not the analytical performance of a diagnostic test.
Therefore, this device falls under the category of a surgical implant, not an In Vitro Diagnostic.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The effectiveness of the Biomet Bone Screw was determined by mechanical testing. The LactoSorb® screws were found to provide the same healing as a stainless steel screw in an animal model. There was no adverse tissue response to either the metal or LactoSorb® screws.
Mechanical testing demonstrated the Biomet Bone Screw to be as effective as the comparative metal and PGA resorbable cancellous screw.

§ 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.

SUMMARY OF SAFETY AND EFFECTIVENESS
Bone Screw is indicated for ankle fractures, The Biomet metatarsal fusions and metatarsal osteotomies (Hallux Valgus).
The screws are made of a resorbable copolymer comprised of polylactic acid (PLA) and polyglycolic acid (PGA). In histological animal studies, the bone screw was completely resorbed by 15 months IN VIVO.
bioresorbable The Biomet Bone Screw is made of and biocompatible polymers that have been used in surgical procedures for years. LactoSorb@ resorbable copolymer is a synthetic polyester derived from lactic and glycolic acids. Polylactic/polyglycolic acid copolymer degrades and resorbs IN VIVO by hydrolysis to lactic and glycolic acids which are then metabolized by the body. The safety of PLA/PGA material has been well documented since the early 1970's when the FDA first approved the use of resorbable PLA/PGA sutures. The exact same LactoSorb® material has been implanted in humans for over 10 years in a ligating clip. The LactoSorb® material has been found to be biocompatible in both soft tissue and bone tissue.
The effectiveness of the Biomet Bone Screw was determined by mechanical testing. The LactoSorb® screws were found to provide the same healing as a stainless steel screw in an animal model. There was no adverse tissue response to either the metal or LactoSorb® screws.
In summary the Biomet Bone Screw is safe and effective for fixation of cancellous bone. Mechanical testing demonstrated the Biomet Bone Screw to be as effective as the comparative metal and PGA resorbable cancellous screw.
