No
The description mentions software for treatment planning and adjustment scheduling based on radiographic images and frame parameters, but it does not describe any AI or ML capabilities such as learning from data, pattern recognition beyond basic calculations, or adaptive algorithms. The software appears to be a calculation and planning tool based on user input and established biomechanical principles.
Yes.
The device is used to stabilize and maintain alignment of fractured bones, soft tissues, and congenital deformity repairs, explicitly mentioning joint contracture, fractures, and limb lengthening as indications, which are all therapeutic interventions.
No
The device is an external fixator system used for orthopedic corrections and stabilization. While it uses radiographic images and a web-based software tool for treatment planning and adjustment scheduling, its primary function is therapeutic (to correct and stabilize) rather than diagnostic (to identify or determine the nature of a disease or condition). The software uses diagnostic data (radiographic images) but does not itself provide a diagnosis.
No
The device description clearly states that the system consists of both hardware (external fixator device with rings and struts) and software (web-based treatment planning tool). While the software is a component, it is not the entirety of the medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description: The WishBone Medical Smart Correction System is a mechanical external fixator device used to stabilize and correct bone and soft tissue issues. It is applied externally to the body.
- Intended Use: The intended uses listed are all related to the mechanical manipulation and stabilization of bones and soft tissues, not the analysis of biological samples.
- Input: The input is radiographic images and direct examination data, not biological samples.
The device is a surgical external fixation system, which falls under a different category of medical devices than IVDs.

Device Description
The purpose of this Traditional 510(k) is to introduce the WishBone Medical Smart Correction System; a multilateral hexapod circular external fixator device used to stabilize and maintain alignment of complicated fractured bones, soft tissues and/or congenital deformity repairs of an extremity. The basic system consists of a minimum of two rings connected by six (6) telescopic struts that are lengthened and shortened independently. The struts' independent motion allows the surgeon to adjust the position of the proximal and distal ring. The system allows for movement in six different axes to correct difficult trauma extremity situations and/or congenital limb deformity correction. The Smart Correction System capitalizes on the body's natural ability of osteogenesis, guiding the orientation and position of this new bone to the desired corrected location in a steady controlled fashion. In addition to the hardware, the Smart Correction System has a web-based software treatment planning tool with Radiographic Navigation. The surgeon enters data from direct examination, radiographic images and the fixator parameters into the software. The software is used preoperatively to plan the reconstruction/correction and identify the frame construction. Post operatively, the surgeon enters the X-ray images and the current frame parameters to establish an adjustment schedule for the patient during the healing process.
The Smart Correction System is modular and facilitates a multitude of frame configurations to serve a wide variety of patient needs. Listed below are the high-level components and accessories:
- The fixator bridge is constructed of two (2) or more ring components, and each ring component is connected to another via six (6) telescopic struts. Full, 2/3, and 1/3 ring components are available, along with standard and rapid adjust struts in multiple lengths. Femoral arches and threaded rods are used as needed to provide added frame stability. Rings and femoral arches are manufactured from aluminum material; struts from titanium, stainless steel, and aluminum; and threaded rods are made from stainless steel material.
- . The fixator bridge is anchored to the patient's bone by crossed tensioned wires and half pins that are secured to the rings by connector elements (wire clamps, pin clamps, cubes, bolts, nuts, washers, and twisted plates). Standard and olive wires are available, as well as multiple diameters and styles of half pins. Pins and wires may also be used to secure fragments of bone; half pins are made from stainless steel and titanium, and wires are made from stainless steel. Connector elements are manufactured out of titanium material.
- A foot ring is available and connected to the distal ring when a procedure such as ankle arthrodesis is performed. The foot rings are manufactured out of aluminum material.
- Patient comfort accessories are also included: strut ID bands (polycarbonate), foot walking attachment (POM-C), and pin/wire caps (silicone, PVC) are also included.
- The Smart Correction System includes reusable surgical instruments to facilitate surgical assembly of the fixator construct. The non-sterile implants and other fixator elements are contained within sterilization cases, along with the reusable instruments.
