Device Story

Internal bone fixation system consisting of anatomically contoured titanium plates and locking screws; used for small bone reconstruction, corrective osteotomies, and fracture fixation in metacarpals and metatarsals. System functions by engaging locking screws into threaded plate holes to create a fixed-angle construct; stabilizes bone fragments and maintains alignment to promote healing. Used in clinical settings by orthopedic surgeons. Healthcare providers select appropriate plate and screw components based on patient anatomy and fracture/osteotomy site. Output is a rigid mechanical construct that provides structural support to bone during the healing process. Benefits include stabilization of bone fragments and maintenance of alignment.

Clinical Evidence

Bench testing only. Mechanical testing performed per ASTM F543 (screws) and non-standard construct-level testing (plates) using synthetic bone models with simulated osteotomies. Testing included static loading (5 mm/min) and cyclic loading (0-31 N at 0.5 Hz for 1,000 cycles). Results compared against predicate devices and literature-supported physiological benchmarks to confirm equivalent structural integrity. No clinical data provided.

Technological Characteristics

Materials: Ti-6Al-4V ELI alloy (ASTM F136, ISO 5832-3). Components: Anatomically contoured plates and locking screws. Principle: Fixed-angle internal fixation. Manufacturing: CNC-machined, surface-finished, laser-marked. Sterilization: Moist heat (ISO 17665) by healthcare provider. Standards: ASTM F382 (plates), ASTM F543 (screws), ISO 10993 (biocompatibility).

Indications for Use

Indicated for small bone reconstruction, corrective osteotomies, and fracture fixation in the metacarpal and metatarsal bones.

Regulatory Classification

Identification

Single/multiple component metallic bone fixation appliances and accessories are devices intended to be implanted consisting of one or more metallic components and their metallic fasteners. The devices contain a plate, a nail/plate combination, or a blade/plate combination that are made of alloys, such as cobalt-chromium-molybdenum, stainless steel, and titanium, that are intended to be held in position with fasteners, such as screws and nails, or bolts, nuts, and washers. These devices are used for fixation of fractures of the proximal or distal end of long bones, such as intracapsular, intertrochanteric, intercervical, supracondylar, or condylar fractures of the femur; for fusion of a joint; or for surgical procedures that involve cutting a bone. The devices may be implanted or attached through the skin so that a pulling force (traction) may be applied to the skeletal system.

Dear Helen Chan:

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, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

| Device Description Summary | | 21 CFR 807.92(a)(4) |
| The APS Spear Locking Plate System (2.4mm locking screw (0824-4302-xx); 2.7mm continuous locking screw (0827-2302-xx); Spear locking plate (1300-0x05-xx); and Spear locking plate ii (1301-0x05-xx)) is an internal fixation device consisting of anatomically contoured titanium plates and associated locking screws, designed for use in small bone reconstruction, corrective osteotomies, and fracture fixation. The system functions by engaging locking screws into threaded plate holes, forming a fixed-angle construct that stabilizes bone fragments, maintains alignment, and promotes healing under rigid fixation principles. All components are manufactured from Ti-6Al-4V ELI alloy (ASTM F136, ISO 5832-3), a biocompatible material with proven use in orthopedic implants. The system includes 2.4 mm Locking Screws, 2.7 mm Continuous Locking Screws, Spear Locking Plates, and Spear Locking Plates II. These implants are CNC-machined, surface-finished, and laser-marked, followed by validated cleaning and packaging. Supplied non-sterile and intended for single use, the devices are sterilized by healthcare providers using moist heat (ISO 17665). Mechanical testing (ASTM F382, ASTM F543) confirms that the plates and screws provide strength, stability, and fatigue resistance comparable to predicate devices, while biocompatibility has been established under the ISO 10993 series. | | |

2.7mm Continuous Locking Screw
The 2.7mm Continuous Locking Screw is intended for use with the Spear Locking Plate, for fixation and compression at the osteotomy or fracture site. It is suitable for metacarpal and metatarsal corrective osteotomies and fracture stabilization.

Spear Locking Plate
The Spear Locking Plate is intended for use in metacarpal and metatarsal reconstruction, corrective osteotomies, and fracture fixation.

Spear Locking Plate II
The Spear Locking Plate II is intended for metacarpal and metatarsal reconstruction, corrective osteotomies, and fracture fixation.

Indications for Use Comparison 21 CFR 807.92(a)(5)

The APS Spear Locking Plate System has the same indications for use as the predicate devices, which include reconstruction, corrective osteotomies, and fracture fixation in small bones.

Technological Comparison 21 CFR 807.92(a)(6)

The APS Spear Locking Plate System is substantially equivalent to the predicate devices, the Synthes 2.4 mm Titanium Locking Screws (K033975) and the Mini MaxLock Extreme Plating System (K101962), in terms of intended use, materials, and performance characteristics. Both systems are intended for use in small bone reconstruction, corrective osteotomies, and fracture fixation, with similar indications for use. The implants are manufactured from comparable titanium alloy materials. Mechanical testing further supports substantial equivalence. Screws were evaluated in accordance with ASTM F543, demonstrating comparable mechanical strength and insertion/ removal torque to the predicate screws. Plates were evaluated in accordance with relevant test methods, including static maximum force, static bending stiffness, and bending stiffness, confirming equivalent structural integrity and mechanical performance to the predicate plating system.

Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)

Mechanical testing was conducted to support substantial equivalence of the APS Spear Locking Plate System. Bone screw testing was conducted in accordance with ASTM F543. For the plate component, testing referenced ASTM F382, but the final plate assessment used a construct-level test setup that deviated from the ASTM F382 plate-only bending configuration, because the subject device is intended to function in a first metatarsal osteotomy fixation construct rather than as an isolated plate. The construct test used first metatarsal synthetic bone models with a reproduced distal metatarsal osteotomy, with lateral-to-medial displacement-controlled static loading (5 mm/min) and plantar-to-dorsal cyclic loading from 0 to 31 N at 0.5 Hz through 1,000 cycles.

This non-standard construct setup was selected to represent clinically relevant functional loading, and interpretation of results was based on both a literature-supported physiological loading benchmark and comparison to the predicate/comparator device under identical test conditions. The results of nonclinical testing support that the APS Spear Locking Plate System is as safe and effective as the predicate device for its intended use. Clinical data were not necessary to support substantial equivalence.
