Methods
olecranon fractures, bony deformities, fractures, rupture
Institutional review board approval was obtained prior to commencement of this study (2022–436-S-SR). Eighteen fresh-frozen cadaver elbows with no gross evidence of tendon injuries, ligament tears, fractures or bony deformities were used in the present study after two specimens had to be excluded due to large olecranon fractures occurring in pilot testing due to poor bone quality. The specimens were thawed for 24 h preceding dissection and testing. Specimens were dissected free of skin and subcutaneous tissue. All soft tissue was removed except for the distal triceps tendon and the triceps brachii muscle. The elbows were exarticulated and only the ulna with the triceps attached were used for testing. The specimens were then randomized to an intact tendon group and a partially ruptured tendon group. For the partially ruptured tendon group, the bony insertion points of the distal triceps tendon were measured using calipers. The size of the footprint was then calculated and 50% of the tendon was cut laterally with a scalpel at the bony attachment including both superficial and deep tendon fibers (Fig. The incision of the distal triceps tendon was cut laterally to simulate a partial tendon rupture of 50% (marked area). Both superficial as well as deep tendon fibres were severed
