Methods: Using 12 unmatched fresh human upper limbs, we evaluated the trajectory of percutaneous transverse K-wire placement relative to the sagittal profile of the fifth metacarpal in order to develop a targeting strategy for treatment of fifth metacarpal fractures. The midpoint of the small and ring finger metacarpals in the sagittal plane was identified at 3 points. At each point, a K-wire was inserted from the small finger metacarpal into the midpoint of the ring finger metacarpal (¡°center-center¡± position). Results: The angle of the transverse K-wire relative to the table needed to achieve a center-center position averaged 20.8¡ă, 18.9¡ă, and 16.7¡ă for the proximal diaphysis, middiaphysis, and the collateral recess, respectively. Approximately 80% of transversely placed K-wires obtained purchase in the long finger metacarpal. Conclusions: These results can serve as a guide to help surgeons in the accurate placement of percutaneous K-wires for small finger metacarpal fractures and may aid in surgeon training %K metacarpal fractures %K transverse percutaneous K-wire fixation %K trauma %K cadaver %U https://journals.sagepub.com/doi/full/10.1177/1558944717691128
