Overview

Formus Hip is the world’s first cloud-based, AI-automated 3D pre-operative planning software specifically designed for primary total hip arthroplasty (THA). It transforms a patient’s CT scan into a fully interactive 3D model of the joint, enabling personalized implant selection and placement. Leveraging cutting-edge AI and computational biomechanics, Formus Hip automatically generates a ready-to-execute surgical plan in under an hour, significantly reducing the time and effort traditionally required for pre-operative planning. This innovative platform empowers surgeons with unprecedented insights, aiming to optimize fit and function, reduce the risk of revision surgeries, and improve overall patient outcomes while enhancing workflow efficiency and potentially reducing costs by up to 25%. The software provides a personalized curated patient surgical plan before the patient enters the operating room, including recommended implant types, sizes, positions, and orientations, along with intraoperative measurements.

What Physicians Need to Know

DICOM Support & Standards
Formus Hip imports patient diagnostic imaging studies, specifically pre-dimensioned CT scans, from PACS systems or other conventional media, implying DICOM compatibility for image transfer.
PACS Integration Method
The software is cloud-based and designed to import patient diagnostic imaging studies directly from PACS systems.
Reading Room Workflow Impact
Formus Hip significantly expedites pre-operative planning for total hip arthroplasty, generating a ready-to-execute surgical plan from a patient CT in under an hour, a process that traditionally could take days or weeks. This enhances workflow efficiency and allows surgeons more time to focus on patient care.
AI Model Architecture (deep learning approach)
The tool utilizes AI and computational biomechanics, specifically an AI-based automatic image segmentation algorithm trained on CT scans and statistical shape models of the femur and pelvis.
Processing Speed (per study)
Formus Hip can automatically generate a 3D pre-operative surgical plan in under an hour from a patient's CT scan.
FDA Clearance Pathway (510k/De Novo)
Formus Hip received 510(k) clearance (K213272) from the United States Food and Drug Administration (FDA) as the first 'automated radiological image processing software' for hip replacement pre-operative planning.
Supported Modalities (CT/MRI/X-ray/US)
Formus Hip primarily supports pre-dimensioned CT scans for its automated 3D pre-operative planning.
Sensitivity & Specificity Data
Non-clinical performance data from the 510(k) submission shows high accuracy: Image Processing Accuracy (3D models from image segmentation) with average Dice scores of 0.95 (Hemipelvis) and 0.97 (Femur), and average Mean Absolute Distances of 1.15mm (Hemipelvis) and 1.35mm (Femur). Implant Sizing accuracy demonstrated 98% for cups and 94% for stems within u00b12 sizes of ground truth.
Physician Tip

Formus Hip offers automated, patient-specific 3D pre-operative planning for total hip arthroplasty, significantly reducing planning time to under an hour. This allows for more efficient workflow and personalized implant selection and placement. Surgeons can interactively review and adjust the AI-generated plans, providing a thorough understanding of each patient's unique anatomy and potentially improving surgical outcomes and reducing revision rates. The detailed reports generated are valuable for surgical execution.

Formus Hip is a cloud-based software that integrates by importing patient CT imaging studies from existing PACS systems. It includes an integrated database of orthopedic hip implant geometries to facilitate planning. Future developments aim to enable planning and post-operative assessment using 2D X-ray and fluoroscopy images.
