Screw Length Associated With Fracture Gapping of Fifth Metatarsal Base Fracture With Intramedullary Screw Fixation: A Cadaveric Study.

Intramedullary screw fixation is a well-established surgical treatment for fifth metatarsal Jones fractures, due to its minimally invasive nature, and potential early return to activity. Due to the curvature of the fifth metatarsal, optimal length of the screw is needed to prevent gapping at the fracture site. The placement of a straight screw induces straightening of a naturally curved bone.
