Method For Reproducible Production Of Defined Bone Fractures

Patent No. EP3491635 (titled "Method For Reproducible Production Of Defined Bone Fractures") was filed by Rimasys on Jul 29, 2016. The application was issued on Jul 26, 2023.

Patent Summary

This method produces a reproducible distal humerus fracture with accompanying soft tissue injuries in a specimen (e.g., a human arm) using a specialized apparatus. The apparatus comprises guide columns, a base plate, a crossmember with a die punch, damping adjustment means, clamping plates, a releasable holding mechanism, and a defined mass (with optional additional weights). To execute the method, a mass of 20.2–27.2 kg is set and dropped from a height of 68–81 cm. The specimen is oriented with the humerus cut surface centrally under the force point and the ulna/olecranon facing upwards, supported by an oblique adapter. Impact parameters are tuned to a compression of 26–37 mm and a damped portion of 0–15 mm to simulate realistic accident mechanisms.
