Operation: hook inserted into passageway until distal end purchase; user aligns thumb slide with analog scale; device provides simultaneous digital readout of depth. Used by surgeons to determine appropriate screw/implant size. Benefits: improved measurement precision compared to traditional analog-only gauges; reduces risk of improper implant sizing. Single-patient use. ## Clinical Evidence Bench testing only. Gauge R&R testing demonstrated 2.48% precision (industry benchmark <10%). Accuracy testing showed the EDG outperformed the analog predicate device (alpha = 0.0005). ## Technological Characteristics Materials: 316 stainless steel probe/hook, Lexan plastic housing. Sensing: Mechanical hook with digital readout. Form factor: Handheld, disposable. Sterilization: Not specified. Software: Embedded digital display logic. ## Regulatory 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. ## Predicate Devices - Acromed Interbody Depth Gauges ([K873191](/device/K873191.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Acromed Interbody Depth Gauges, K873191 Buckman Co., Inc. | | Device Description | The Eidosmed Electronic Depth Gauge (“EDG”) is a depth gauge
measuring device intended for various medical purposes, including
but not limited to, measuring the depth of a passageway in a bone
or other tissue to enable insertion of properly sized screws and
implants. In addition to mechanically measuring and displaying
depth using an analog scale, the EDG displays this information
using a digital readout. The EDG, referred to as the EDG 4.0
version, is a completely disposable device. It is intended to be
used on one patient, over the course of one surgical procedure. | {1}------------------------------------------------ ## EIDOSMED LLC EDG Depth Gauge Page 2 of 2, 510(k) Summary . | Intended Use and
Indications | The Eidosmed EDG is a depth gauge measuring device intended for
various medical purposes including but not limited to, measuring
the depth of a passageway in a bone or other tissue to enable
insertion of properly sized screws and implants. | |-----------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | Technological
Characteristics and
Substantial Equivalence | The Eidosmed EDG has many similar technological characteristics
and is substantially equivalent to the predicate.
The method of use for the EDG device is exactly the same as the
predicate. Both devices use a hook inserted, in a linear motion,
into the passageway until the indented hook purchases the distal
end of the bone. The user then visually aligns the thumb slide with
the analog scale printed on the outer housing, correlating to the
depth of the bone. Finally, the hook is removed from the
passageway.

The material used in the EDG is also similar to those used in the
predicate. Both devices use medical grade 316 stainless steel for
the probe/hook inserted into the bone or tissue. The Lexan plastic
has been evaluated and found compliant to the most stringent
biocompatibility test standards.

Both the EDG and the predicate device have GR&R values well
below the 10% industry benchmark. | | Performance
Testing/Data | Tests were performed on the device which demonstrated that the
device is safe and effective, performs comparably to and is
substantially equivalent to the predicate device.

The results for the Gauge R & R testing resulted in a statistically
significant value of 2.48% which signifies excellent precision.
Additionally, the accuracy of EDG outperformed the accuracy of
the analog device (with an alpha = .0005). Because both the EDG
and the predicate device have below 10% values for GR&R, it can
be concluded that the devices are substantially equivalent | • . {2}------------------------------------------------ Image /page/2/Picture/1 description: The image shows the seal of the Department of Health & Human Services - USA.
