Foot Fracture Plating Systems for Complex Anatomies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved plate styles and plating systems that can effectively treat a wide array of fracture patterns and accommodate multiple deformities, particularly in complex three-dimensional geometries of the foot and ankle.
Innovation Solution
The development of a comprehensive range of bone stabilization plates and systems, including 5th metatarsal hook plates, coupled Lisfranc tarsometatarsal plates, flower plates, utility plates, and sinus tarsi wave plates, designed to accommodate various fracture patterns and anatomical regions. These plates can be cut and contoured to fit individual patient anatomy and come in a variety of sizes and styles to address multiple deformities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a comprehensive range of plate styles and sizes is developed to treat various fracture patterns and anatomical regions, then the adaptability and versatility of the plating system is improved, but the device complexity and number of components increases
Solution Approach 1:
The patent applies universality by designing plates with multiple functional features integrated into single components. For example, plates include both locking and non-locking screw holes, contoured surfaces for anatomical fitting, and options for both definitive and temporary fixation within the same plate design, reducing the need for multiple specialized plate types
Solution Approach 2:
The patent applies segmentation by offering plates in modular size variations and configurations that can be selected based on specific anatomical needs. The system divides the comprehensive solution into standardized plate sizes and styles (e.g., different lengths, widths, and contour profiles) that maintain design consistency while addressing various fracture patterns and anatomical regions
2Adaptability or versatility
If plates are designed to be cut and contoured to accommodate extreme patient anatomy, then the adaptability to individual patient needs is improved, but the ease of manufacture and standardization decreases
Solution Approach 1:
The patent applies local quality by incorporating pre-contoured surfaces and anatomical shaping in specific regions of the plates while maintaining straight or minimally contoured sections that are easier to manufacture. This allows selective adaptation to anatomical variations without requiring complete customization of each plate
3Reliability
If locking fasteners are used to connect the plate to the bone, then the stability and reliability of fixation is improved, but the ability to dynamically compress the bone and create interfragmental compression is reduced
Solution Approach 1:
The patent applies dynamics by incorporating both static locking mechanisms and dynamic compression capabilities into the fastening system. The plate includes specialized holes and slots that allow non-locking fasteners to provide dynamic compression while other holes accommodate locking fasteners for stable fixation, enabling the system to transition between rigid and flexible states as needed

AI summary
Devices, systems, and methods for promoting healing and stability for bone fractures. The bone stabilization system may include a variety trauma and/or reconstruction plates and one or more bone fasteners configured to secure the plate to bone. The bone plates may be used for the fixation of fractures and fragments in forefoot, midfoot, and hindfoot applications. The foot fracture plating may be used to create a rigid construct with permanent fixation to promote primary healing and stability.
