Midbody fracture of the proximal sesamoid bone - screw fixation

Placement of radiographic markers

If advanced imaging technologies are not available, 19 gauge 1.5 inch (3.8 cm) needles are used as radiographic markers to assist the surgeon with screw placement.
The needles are placed under arthroscopic supervision at the apex, base, and fracture line of the proximal sesamoid bone in both the frontal and sagittal planes.
