Pelvic Wedge Implant Segmentation for Balance Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for correcting spinal and pelvic imbalances are complex, expensive, and time-consuming, and existing implants do not effectively restore balance parameters of the spine and pelvis.
Innovation Solution
A surgical implant assembly comprising a surgical implant with a triangular shape, a bone plate, and fixation devices, designed to be securely attached to osseous tissue, featuring cavities for bone growth material and channels for fixation devices, which can be customized for specific anatomical needs and procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical procedures are used to correct spinal and pelvic imbalances, then the balance parameters can be corrected, but the procedure becomes complex, expensive, and time-consuming
Solution Approach 1:
The pelvic correction is divided into two independent stages: first inserting the surgical implant to establish proper pelvic orientation and balance parameters, then performing the osteotomy to permanently reshape the pelvis. This segmentation allows each stage to be optimized independently and reduces overall procedural complexity.
Solution Approach 2:
The surgical implant is inserted and positioned to achieve the desired pelvic balance parameters before the actual osteotomy procedure. This preliminary positioning allows the surgeon to verify correct alignment and balance correction before committing to the permanent bone reshaping, reducing the need for complex revisions.
2Reliability
If traditional surgical procedures are used to correct spinal and pelvic imbalances, then the balance parameters can be corrected, but the cost and recovery time increase
Solution Approach 1:
By separating the pelvic positioning function (surgical implant) from the permanent correction function (osteotomy), the procedure allows for more efficient surgical execution. The implant can be quickly inserted and adjusted, while the osteotomy is performed once optimal positioning is confirmed, reducing total surgical time and subsequent recovery requirements.
3Ease of manufacture
If existing implants are used, then spinal and pelvic imbalances can be addressed, but the balance parameters are not effectively restored
Solution Approach 1:
The surgical implant is designed with specific geometric features (triangular cross-section, angled surfaces) that directly correspond to the desired pelvic balance parameters. The implant's local geometry at the insertion site enables precise control over pelvic orientation, achieving balance restoration that generic implants cannot provide.
Solution Approach 2:
The surgical implant enables direct modification of key pelvic balance parameters (pelvic tilt, sacral slope, pelvic incidence) through its specific angular geometry and orientation. By changing the physical parameters of the implant design rather than relying on soft tissue or muscular adjustments, the procedure achieves more reliable and predictable balance parameter restoration.

AI summary
A surgical implant assembly includes a surgical implant, a bone plate, and fixation devices. The surgical implant includes a top surface, a bottom surface disposed in opposed relation relative to the top surface, first and second surfaces interconnecting the top and bottom surfaces, and a front surface. First ends of the first and second side surfaces define a back surface extending across a first end of the surgical implant, and the front surface extends across a second end of the surgical implant and interconnects second ends of the first and second side surfaces. At least one cavity is defined in the surgical implant. The bone plate includes an elongate body extending between first and second end portions. The elongate body is positionable adjacent the front surface of the surgical implant. The fixation devices are configured to secure the surgical implant or the bone plate to osseous tissue.
