Manufactured from EndoSorb™ (polyester derivative of L-Lactic and glycolic acids/PLGA); material degrades in vivo via hydrolysis into L-lactic and glycolic acids. Features hexagonal twist-off head portion to ensure flush seating with bone surface. Used by surgeons in clinical settings for metacarpal/phalangeal fusion/fracture and hallux valgus repair. Device provides mechanical stabilization during bone healing; absorbs over time, eliminating need for secondary removal surgery. ## Clinical Evidence Bench testing only. Tests included in vitro degradation (strength/viscosity), inherent viscosity, glass transition temperature, crystallinity, breakage strength, insertion torque, and long-term/transport stability. ## Technological Characteristics Material: EndoSorb™ (PLGA - poly(L-lactide-co-glycolide)). Principle: Absorbable bone fixation fastener. Form factor: Screw with hexagonal twist-off head. Sterilization: Not specified. Connectivity: None. ## Regulatory 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. ## Predicate Devices - ProToe™ EndoSorb™ Small Hammer Toe Pin, Merete ([K100414](/device/K100414.md)) - Reunite Screws, Biomet ([K992301](/device/K992301.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

EndoSorb™ is a polyester derivative of L-Lactic and glycolic acids. Poly(L-lactide-co-dlycolide) material (PLGA) degrades and absorbs in vivo by hydrolysis into L-lactic and glycolic acids, which are then metabolized by the screw head provides a hexagonal twist off portion to enable screw head to be flush with the bone. Merete Medical GmbH {1}------------------------------------------------ Submission Date: 08 / 24 / 2010 # Substantial Equivalence: The TwistCut™ EndoSorb™ Bone Screws similar to legally marketed predicate device listed above in that it shares similar indications for use, is manufactured from similar materials and incorporate similar technological characteristics. Any differences have been found to have no obvious effect on the performance, function, or intended use of the prosthesis. The following bench tests were performed: - . In vitro degradation test (determination of decreasing strength and inherent viscosity) - Determination of inherent viscosity, glass transition temperature and crystallinity . - . Brakeage strength and insertions torque - Long-term stability of package and subject device . - . Stability test under extreme transport conditions - Temperature limit for storage . - A geometrical and a material comparison of the subject and the predicate devices were . provided. This information served as a basis for a determination of substantial equivalence. The predicates for the subject device are ProToe™ EndoSorb™ Small Hammer Toe Pin, Merete (K100414); Reunite Screws, Biomet (K992301). # Software Documentation: No software is needed for the use of this device. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the logo for the Department of Health & Human Services-USA.
