Summary
SecureStrap (SS) mesh fixation devices demonstrated superior strength at acute angles (30°) compared to SorbaFix (SF), reducing immediate failures in hernia repair. Optimal fixation depends on device and angle, not loading direction.
Area of Science:
- Surgical Engineering
- Biomaterials Science
- Hernia Repair Devices
Background:
- Suboptimal mesh fixation is a cause of hernia repair failure.
- Mechanical construct design and deployment angle influence mesh-tissue fixation strength.
- Absorbable fixation devices are used to secure surgical mesh.
Purpose of the Study:
- To compare the acute fixation strengths of different absorbable mesh fixation devices.
- To evaluate the impact of deployment angles, loading directions, and construct orientations on fixation strength.
Main Methods:
- Porcine abdominal wall tissue was used for fixation testing.
- Absorbable fixation devices (Absorbatack™, SorbaFix™, SecureStrap™) were deployed at angles of 30°, 45°, 60°, and 90°.
- Lap-shear testing evaluated fixation strength under various loading directions and construct orientations; statistical analysis was performed.
Main Results:
- SecureStrap™ (SS) showed significantly greater fixation strength than SorbaFix™ (SF) at 30° and 45° angles.
- No significant differences in fixation strength were observed at 60° or 90° angles.
- SorbaFix™ (SF) and the 30° deployment angle were associated with increased immediate mesh failures.
Conclusions:
- Mesh-tissue fixation strength is angle-dependent, with acute angles (30°) favoring SecureStrap™ (SS) over SorbaFix™ (SF).
- The SecureStrap™ (SS) device and acute deployment angles enhance fixation strength and reduce immediate failures.
- Loading direction and construct orientation did not significantly impact the fixation strength of these devices.
