Reverse Shoulder Arthroplasty Planning via Virtual 3D Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current shoulder arthroplasty procedures face challenges in restoring a full range of motion, especially for surgeons less experienced, due to limitations in pre-operative planning and intra-operative selection of prosthetic components, leading to suboptimal patient outcomes.
Innovation Solution
The development of systems and methods that utilize virtual surgery and 3D modeling to pre-operatively plan reverse shoulder arthroplasty by segmenting patient images, performing virtual resections and reaming, selecting and positioning virtual implant components, and analyzing range of motion to create a personalized surgical plan, which can be adjusted based on desired outcomes and daily activity requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional pre-operative planning and intra-operative selection methods are used, then the surgical procedure can be performed, but the range of motion restoration is limited and outcomes are suboptimal
Solution Approach 1:
The system performs virtual surgery and range of motion analysis before the actual surgical procedure. Surgeons can plan implant positioning, resection angles, and component selection in advance using patient-specific 3D models, allowing optimization of expected range of motion outcomes before entering the operating room.
Solution Approach 2:
The system creates virtual copies of the patient's shoulder anatomy through 3D modeling from medical images. These digital replicas allow for virtual trial of different surgical approaches and implant configurations without affecting the actual patient, enabling precise prediction of functional outcomes.
2Measurement precision
If virtual surgery and 3D modeling are implemented, then pre-operative planning accuracy is enhanced, but system complexity and computational requirements increase
Solution Approach 1:
The system integrates multiple functions into a unified platform: 3D image processing, virtual surgery simulation, range of motion analysis, and surgical planning all within a single software environment. This multi-functionality reduces the need for separate tools and streamlines the workflow despite the advanced capabilities provided.
3Ease of operation
If virtual implant positioning and range of motion analysis are performed, then intra-operative decision complexity is reduced, but computational time and processing power are consumed
Solution Approach 1:
All complex computational analysis, including virtual implant positioning and range of motion simulation, is completed during the pre-operative planning phase. The results are presented to the surgeon before surgery, eliminating the need for time-consuming calculations during the actual procedure and allowing focused execution of the predetermined plan.

AI summary
A method of pre-operatively developing a reverse shoulder arthroplasty plan can include receiving an image of a patient shoulder comprising a humerus and a glenoid. The image can be segmented to develop a 3D shoulder model. Virtual surgery can be performed on the 3D shoulder model to generate a modified shoulder model. The virtual surgery can include resecting and reaming a virtual humerus of the 3D shoulder model, and reaming a virtual glenoid of the 3D shoulder model. Selection of a humeral implant and selection of a glenoid implant can be received. A virtual representation of the humeral implant can be implanted on the virtual humerus and a virtual representation of the glenoid implant on the virtual glenoid to virtually update the modified shoulder model. A range of motion of the patient shoulder can be determined and a reverse shoulder arthroplasty can be finalized based on the range of motion.
