Anterior Hip Joint Access via Pelvic Bone Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hip joint replacement surgeries often require penetrating the hip joint capsule, leading to prolonged recovery times, increased risk of infection, and strain on the joint, as well as removal of healthy femur bone and large blood vessels, which can result in complications such as blood clots.
Innovation Solution
A surgical and laparoscopic/arthroscopic method that accesses the hip joint through a hole in the pelvic bone, allowing for the placement of an artificial hip joint surface without damaging the joint capsule, using techniques like expandable reamers and resorbable materials, and flexible artificial components that can be inserted through smaller openings, reducing tissue disruption and promoting quicker recovery.

Engineering Contradiction Analysis
1Ease of operation
If conventional surgery penetrating the hip joint capsule is used to access the hip joint, then the hip joint can be accessed for surgery, but the hip joint capsule is damaged making it difficult to achieve a fully functional joint after surgery
Solution Approach 1:
Instead of accessing the hip joint from the lateral side through the hip joint capsule (conventional approach), the invention inverts the approach by accessing the hip joint from the anterior side through the pelvic bone. This reversal of the surgical pathway allows complete avoidance of the hip joint capsule, eliminating capsule damage while maintaining surgical accessibility to the hip joint surfaces.
2Ease of operation
If conventional hip joint surgery is performed through lateral incision, then the hip joint can be accessed, but the recovery time is prolonged (one week hospitalization and 6 weeks recovery)
Solution Approach 1:
The invention inverts the surgical approach from lateral capsule penetration to anterior bone access, which creates a minimally invasive pathway. This inverted approach avoids damaging the hip joint capsule and surrounding soft tissues, resulting in reduced postoperative pain, shorter hospitalization (one day), and faster recovery (two weeks) compared to conventional surgery.
3Ease of operation
If conventional surgery removes femur bone and affects large blood vessels, then the hip joint can be accessed, but the risk of blood clots increases
Solution Approach 1:
Instead of accessing the hip joint from the lateral side where large blood vessels and extensive soft tissue structures are encountered, the invention inverts the approach to access through the anterior pelvic bone. This pathway avoids disruption of large blood vessels and minimizes trauma to soft tissues, thereby significantly reducing the risk of postoperative blood clots and other complications.

AI summary
A method of treating a hip joint of a human is provided. The method comprises a step of dissecting an area of the pelvic bone, comprising at least one of the following: dissecting an area between peritoneum and the pelvic bone, dissecting an area between the pelvic bone and the surrounding tissue, dissecting an area of the pelvic region, and dissecting an area of the inguinal region, or, the method comprises at least two of the following steps: dissecting an area of the abdominal cavity, penetrating the hip joint capsule, dissecting an area between peritoneum and the pelvic bone, dissecting an area of the pelvic bone which comprises: dissecting an area between the pelvic bone and the surrounding tissue, or dissecting an area of the pelvic region, or dissecting an area of the inguinal region, and removing or penetrating the tissue surrounding the pelvic bone in the area opposite to acetabulum.
