Intended Use

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 (K071546), the sterEOS Workstation provides interactive 3D measurement tools: To aid in the analysis of scoliosis and related disorders and deformities of the spine in adult patients as well as pediatric patients 7 years and older. The 3D measurement tools include interactive analysis based on 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. The model of bone structures is not intended for use to assess individual vertebral abnormalities. To aid in the analysis of lower limbs alignment and related disorders and deformities based on angle and length measurement . The 3D measurement tools include interactive analysis based either on identification of lower limb alignment landmarks or as for the spine, on a model of bone structures derived from an a priori image data set. The model of bone structures is not intended for use to assess individual bone abnormalities. The 3D package including model-based measurements and torsion angles is indicated only for patients 15 years or older. Only the 2D/3D ruler is indicated for measurements in patients younger than 15 years old.

Device Story

Workstation for acceptance, transfer, display, storage, and digital processing of 2D X-ray images; utilizes 2D images from EOS System (K071546) to generate interactive 3D measurements. Operates via clinician-driven interactive analysis; employs a priori bone structure models derived from 175-patient dataset and dry vertebrae data. Used in clinical settings by radiologists and orthopedists to analyze scoliosis, spinal deformities, and lower limb alignment. Output includes 2D/3D measurements, torsion angles, and alignment data; aids clinical decision-making by providing quantitative skeletal analysis. Benefits include improved assessment of complex musculoskeletal deformities.

Clinical Evidence

Bench testing and clinical image validation. Accuracy and precision of 3D model-based measurements confirmed using X-ray clinical images for patients with Cobb's angle > 50°. Results demonstrate equivalent performance to conventional measurement methods on native X-rays.

Technological Characteristics

Supports DICOM 3.0 images; Windows 7 OS; off-the-shelf hardware. Features interactive 2D/3D measurement tools; model-based analysis using a priori bone structure datasets. Standard clinical workflow interface.

Indications for Use

Indicated for pediatric (≥7 years for spine; ≥15 years for 3D lower limb model) and adult patients requiring musculoskeletal radiology/orthopedic analysis. Used for scoliosis, spinal deformities, and lower limb alignment disorders. Contraindicated for assessing individual vertebral or bone abnormalities using the 3D model.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

Special Controls

{1}------------------------------------------------

#### Device Description:

The sterEOS Workstation is a general system for acceptance, transfer, display, storage, and digital processing of 2D X-ray images of the musculoskeletal system, including interactive 2D measurement tools.

When used with 2D X-ray images obtained with the EOS imaging's EOS System (K071546), the sterEOS Workstation provides interactive 3D measurement tools to aid in the analysis of skeletal deformities in spine and lower limbs.

#### Indications for Use:

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 System (K071546), the sterEOS Workstation provides interactive 3D measurement tools:

- To aid in the analysis of scoliosis and related disorders and deformities of the spine in adult ◆ patients as well as pediatric patients 7 years and older. The 3D measurement tools include interactive analysis based on 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. The model of bone structures is not intended for use to assess individual vertebral abnormalities.
- To aid in the analysis of lower limb alignment and related disorders and deformities. The 3D . measurement tools include interactive analysis based either on identification of lower limb alignment landmarks or as for the spine, on a model of bone structures derived from an a priori image data set. The model of bone structures is not intended for use in pediatric patients and is not intended for use to assess individual bone abnormalities. The 3D package including model-based measurements and torsion angles is indicated only for patients 15 years or older. Only the 2D/3D ruler is indicated for measurements in patients younger than 15 years old.

#### Technological Characteristics:

The sterEOS Workstation supports DICOM 3.0 formatted images. The sterEOS Workstation is based on the Windows 7 operating system and runs on off-the-shelf hardware. The sterEOS Workstation user interface follows typical clinical workflow patterns to process, review, and analyze digital images.

{2}------------------------------------------------

#### Performance Data:

Accuracy and precision of the automatic measurements computed from the 3D model of the spine in patients with Cobb's angle > 50° have been confirmed with X-ray clinical images. Results validate the interactive 3D measurement tools for a severe scoliosis assessment and demonstrate the equivalent performance of the device with conventional measurement methods performed on native X-ray images.

#### Substantial Equivalence:

The sterEOS Workstation expands the indications for use of the company's cleared sterEOS device to include patients with Cobb's angle > 50°. The sterEOS Workstation for the expanded indication for use is as safe and effective as the company's cleared sterEOS device (K080529, K090050, K101398). The device has the same intended uses and similar indications, technological characteristics, and principles of operation as its predicate device. The minor 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 device and, thus, is substantially equivalent.
