Unknown
The description mentions a "model of bone structures derived from an a priori image data set" used for interactive 3D measurement tools. While this could potentially involve machine learning for model generation or fitting, the summary does not explicitly state the use of AI or ML techniques. The description of the "a priori image data set" as a training set is suggestive, but not definitive proof of ML.
No
The device aids in analysis and measurement of images, but it does not directly provide therapy.
Yes
The device aids in the analysis of skeletal deformities and disorders, such as scoliosis and lower limb alignment, using quantitative measurements from X-ray images, which are used to inform diagnosis and treatment planning.
No
The device is described as a "Workstation," which typically implies a hardware component (a computer or dedicated system) running the software. While the primary function is software-based image processing and measurement, the description doesn't explicitly state it is only software and relies on a separate hardware platform not included in the device definition. It also mentions being used with the EOS System, which is a hardware imaging device.
Based on the provided information, the sterEOS Workstation is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- sterEOS Workstation's Function: The sterEOS Workstation processes and analyzes images (2D X-ray images) of the musculoskeletal system. It does not interact with or analyze biological specimens taken from the patient.
- Intended Use: The intended use clearly states its purpose is for processing and analyzing X-ray images to aid in the analysis of skeletal deformities and alignment. This is a function related to medical imaging and image analysis, not in vitro testing of biological samples.
Therefore, the sterEOS Workstation falls under the category of medical imaging software or a picture archiving and communication system (PACS) with advanced analysis capabilities, rather than an IVD.

Description of the training set, sample size, data source, and annotation protocol
A model of bone structures derived from an a priori image data set from 175 patients (91 normal patients, 47 patients with moderate idiopathic scoliosis and 37 patients with severe idiopathic scoliosis), and dry isolated vertebrae data for spine modeling.
Description of the test set, sample size, data source, and annotation protocol
Revision of contraindications has been assessed through functional testing of the spine 3D modeling workflows for the no longer contraindicated types of spine with extra vertebra, spine with missing vertebra, and spine with spondylolisthesis.
In addition, a functional evaluation study conducted by internal experienced radiographers from EOS imaging has been conducted to verify the ease to perform a 3D modeling and to obtain an adjusted outline of the final 3D model that matches the vertebrae of spines with extra or missing vertebrae and spines with spondylolisthesis.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Revision of contraindications has been assessed through functional testing of the spine 3D modeling workflows for the no longer contraindicated types of spine with extra vertebra, spine with missing vertebra, and spine with spondylolisthesis.
In addition, a functional evaluation study conducted by internal experienced radiographers from EOS imaging has been conducted to verify the ease to perform a 3D modeling and to obtain an adjusted outline of the final 3D model that matches the vertebrae of spines with extra or missing vertebrae and spines with spondylolisthesis. This functional evaluation study did not intend to provide any information related to reproducibility or reliability of 3D spine modeling and related clinical parameters.
Results showed that the revised contra-indications do not raise different safety or effectiveness concerns as with the cleared sterEOS.
Software modifications have been verified at the unit level. After integration, system software verification and validation testing were performed to ensure compliance with specifications, performance and non-regression.
Additional performance and functional testing has confirmed the equivalent performance of the modified sterEOS Workstation compared to the predicate sterEOS.

The sterEOS Workstation is intended for use in the fields of musculoskeletal radiology and orthopedics in both pediatric and adult populations as a general device for acceptance, transfer, display, storage, and digital processing of 2D X-ray images of the musculoskeletal system including interactive 2D measurement tools.
When using 2D X-ray images obtained with the EOS Imaging EOS System, the sterEOS Workstation provides interactive 3D measurement tools:

Only the 2D/3D ruler is indicated for measurements in patients younger than 15 years old.
Summary of Technological Characteristics
The technological characteristics of the modified sterEOS Workstation are essentially identical to the cleared sterEOS Workstation (K160914). Like the cleared predicate, the subject device is based on the Windows 7 operating system, runs on off-the-shelf hardware, supports DICOM 3.0 formatted images, and has a user interface that follows typical clinical workflow patterns to process, review, and analyze digital images.
The subject device incorporates a revision of contra-indications related to spine modeling which has been modified as follows:
- . Previous contra-indication (cleared sterEOS):
- The 3D spine modeling software may not be used in the following cases:
- spinal columns with supernumerary vertebrae (one extra or one fewer thoracic or lumbar vertebra),
- vertebrae with severe congenital deformities (e.g. hemivertebrae, spina bifida, etc.),
- spondylolisthesis.
5
- Revised contra-indication (modified sterEOS):
The 3D spine modeling software does not allow modeling of vertebrae with severe congenital deformities (e.g. hemivertebrae, spina bifida, etc.). The modeling of a spine including vertebrae with congenital deformities may be performed by leaving out the vertebrae with the severe congenital deformity.
The modified sterEOS also includes several minor software modifications:
- Improvement of patient report creation; -
- Improvement of sterEOS 3D module launching time by replacement of Matlab runtime executable by C++ runtime executable and change of compilation process from 32 bits to 64 bits;
- -Improvement of sterEOS export/import capabilities;
- -Various bug corrections.
Minor hardware modifications were also made following obsolescence.
Performance Data
Revision of contraindications has been assessed through functional testing of the spine 3D modeling workflows for the no longer contraindicated types of spine with extra vertebra, spine with missing vertebra, and spine with spondylolisthesis.
In addition, a functional evaluation study conducted by internal experienced radiographers from EOS imaging has been conducted to verify the ease to perform a 3D modeling and to obtain an adjusted outline of the final 3D model that matches the vertebrae of spines with extra or missing vertebrae and spines with spondylolisthesis. This functional evaluation study did not intend to provide any information related to reproducibility or reliability of 3D spine modeling and related clinical parameters.
Results showed that the revised contra-indications do not raise different safety or effectiveness concerns as with the cleared sterEOS.
Software modifications have been verified at the unit level. After integration, system software verification and validation testing were performed to ensure compliance with specifications, performance and non-regression.
Additional performance and functional testing has confirmed the equivalent performance of the modified sterEOS Workstation compared to the predicate sterEOS.
Conclusions
The modified sterEOS Workstation is as safe and effective as the cleared sterEOS Workstation (K160914). The device has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device. In addition, the minor technological differences between the device and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that the device is as safe and effective as the company's cleared sterEOS Workstation (K160914) and, thus, is substantially equivalent.
