Current classification systems of coronoid fractures are based on plain radiographic and/or CT measurements where cartilage is radiolucent and therefore not taken into account. Hence, during surgery, coronoid fracture fragments are much larger than anticipated for when viewed on CT. The main goal of this research is to determine the ulnar coronoid cartilage thickness in order to aid surgeons and clinicians in the proper classification and operation of coronoid bone fractures. Thirty ulnas have been dissected from embalmed cadaveric upper extremities and placed into a 30% diluted hypaque cartilage contrasting agent prior to CT. Using OsiriX (3.6–64 bit), 3‐D models for each ulna were constructed. Using the OsiriX point tool, 12 identifiable landmarks were placed onto the ulnar coronoid process, and then translated onto 2D orientation slices. This serves the purpose of measuring cartilage thickness from coronal, sagittal, and axial coronoid CT slices. Knowing the cartilage thickness will not only allow for proper classification of ulnar coronoid fractures by surgeons/clinicians, but will also allow for the accurate engineering of coronoid head prostheses in cases of irreparable coronoid process fractures. Moreover, discrepancies between biomechanical/anatomical studies and clinical outcome studies could then be resolved. Grant Funding Source : Internal
