Dataset for "Anatomical Feasibility of Using Shark Screw® Tendon for Humeral Ligament

This dataset contains the complete anatomical and biomechanical raw data generated in an exploratory cadaveric feasibility study evaluating the use of the Shark Screw® Tendon for humeral fixation in medial ulnar collateral ligament (UCL) and lateral ulnar collateral ligament (LUCL) reconstruction of the elbow.
The study was performed on 16 unfixed upper extremity specimens from adult body donors. After anatomical preparation, triceps tendon grafts (approx. 70 × 5 mm) were harvested and used for ligament reconstruction. Ulnar fixation was performed using an Endobutton technique, while humeral fixation was achieved using the Shark Screw® Tendon (5.0 mm diameter, 15 mm length). In selected specimens, fixation using a biocomposite interference screw (Swivelock 4.75 mm) was performed for comparison.
The dataset includes:
Demographic specimen dataDocumentation of surgical feasibility Drilling orientationTunnel dimensions and implant specificationsQuantitative measurements of graft elongationafter cyclic flexion–extension testingafter cyclic pronation–supination testingAxial load-to-failure measurements assessing humeral fixation strengthDocumentation of failure modeMeasurement protocols and surgical workflow documentationFor primary stability assessment, graft position at the humeral entry point was marked and displacement was measured after cyclic loading. Subsequently, a linearly increasing axial force was applied until fixation failure occurred, and maximum load-to-failure was recorded.
All specimens were pseudonymized prior to data acquisition and analysis. No identifiable personal data are included.
The dataset enables reproducibility of the reported results and allows independent verification of anatomical feasibility and primary biomechanical stability of humeral fixation using the Shark Screw® Tendon.
