Implant features threaded portion for proximal phalanx engagement and barbed portion for distal phalanx fixation. Available in 2.0mm and 4.0mm diameters with 0° or 10° angle configurations. System includes manual instrumentation: guide wires, broaches, cannulated drills, and drivers. Used by surgeons in clinical settings to facilitate interdigital repair and fusion of phalanges. Implant provides bone-to-bone contact to stabilize osteotomies during healing. Benefits include rigid fixation for hammertoe, claw toe, and mallet toe correction. ## Clinical Evidence Bench testing only. No clinical data provided. Verification testing included pullout and bending tests to confirm mechanical strength meets requirements for intended use. ## Technological Characteristics Implant material: Titanium alloy (Ti6Al4V) per ASTM F136. Instrumentation materials: surgical grade stainless steel, anodized aluminum, medical grade plastic. Design: one-piece threaded/barbed cannulated fastener. Dimensions: 2.0mm and 4.0mm diameters; 0° and 10° angles. Mechanical fixation principle. ## 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 - OsteoMed ExtremiFuse System ([K130412](/device/K130412.md)) - Metasurg DigiFuse System ([K111536](/device/K111536.md)) - OsteoMed Foot Plate and Screw Rigid Fixation System ([K091614](/device/K091614.md)) - OsteoMed Extended 2.0/2.4 Cannulated Screw System ([K062863](/device/K062863.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The ExtremiFuse implant is a one piece implant with a threaded portion and a barbed portion that holds the resected faces of the two phalanges together. The implant is offered in 4 diameter sizes of 2.0mm, 2.0mm and 4.0mm. For each size, the implant is available in angle configurations of 0° and 10°. The system instruments include guide wires, broaches, cannulated drills, and implant drivers to facilitate the placement of the implants. The ExtremiFuse implants are made from implant grade titanium alloy (Ti6Al4V) per ASTM F136. The instrumentation is made from various grades of surgical grade stainless steel, anodized aluminum, and/or medical grade plastic. ## Intended Use: The OSTEOMED ExtremiFuse System is indicated for the fixation of osteotomies and reconstruction of the lesser toes following correction procedures for hammertoe, claw toe, and mallet toe. ## Technological Characteristics: The 2.0mm OSTEOMED ExtremiFuse implant is recommended for arthrodesis of the proximal interphalangeal (PIP) joints of the Lesser Digits. The threaded portion of the implant is screwed into the proximal phalance to engage the bone and create a solid base. Following pilot drilling. the barbed side is pressed into the remaining distal phalange to create bone to bone contact during fixation. ExtremiFuse devices are manufactured from titanium alloy (Ti6Al4V). This material is biocompatible. # Performance / Clinical Data: The 2.0mm OSTEOMED ExtremiFuse System implants were compared to the Metasurg DigiFuse Implant, the OSTEOMED Cannulated Screw System, and the OSTEOMED Foot Plating System, K-Wires. The ExtremiFuse implants underwent verification to ensure that the design features met the required mechanical strength criteria for their intended use. The intended use of the OSTEOMED 2.0mm ExtremiFuse implant is the same as the OsteoMed ExtremiFuse System (K130412) and Metasurg DigiFuse Implant System (K101165). Clinical Testing is not required to support substantial equivalence. {2}------------------------------------------------ In conclusion, the device was evaluated to be safe and effective in performing as well or better when compared to the predicate devices for the intended use. #### Substantial Equivalence: A design and dimensional comparison was performed to establish substantial equivalence to the legally marketed predicate devices listed in this summary. The basis of substantial equivalence for this device is based on similarities in intended use, function, performance, design, technology and operational principles to the OsteoMed ExtremiFuse System (K130412), Metasurg DigiFuse System (K111536), and similarities in material, function, performance, and operating principles to the OsteoMed Cannulated Screw System (K062863) and OsteoMed Foot Plating System, K-Wires (K091614). Substantial equivalence was shown through the pullout test, and bending test to the predicate devices. The indications, design, technology and operational principles are similar between the subject and predicate, OsteoMed ExtremiFuse System, Metasurg DigiFuse System, and therefore OsteoMed believes that the addition of the 2.0mm implant to the scope of OSTEOMED ExtremiFuse System does not raise any new safety or effectiveness issues. {3}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 10903 New Hampshire Avenue Document Control Center - WO66-G609 Silver Spring, MD 20993-0002 February 28, 2014 OsteoMed Blesson Abraham Regulatory Affairs Specialist 3885 Arapaho Road Addison, Texas 75001 Re: K140283 Trade/Device Name: OsteoMed ExtremiFuse™ System Regulation Number: 21 CFR 888.3040 Regulation Name: Smooth or threaded metallic bone fixation fastener Regulatory Class: Class II Product Code: HWC Dated: January 31, 2014 Received: February 4, 2014 Dear Mr. Blesson Abraham: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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.
