Finally, the system includes instrumentation for a cannulated technique to facilitate the surgeons preferred method of implanting with a cannulated or solid screw for fixation. This Nitinol K-wire is designed to flex and follow the curvature of the intramedullary canal while limiting the chance of broaching the surrounding cortex. The patent pending PRECISION® Jones Curved K-wire Guide positions a Nitinol K-wire into the center of the intramedullary canal simplifying placement which may reduce intraoperative fluoroscopy time.
The system includes instrumentation designed to facilitate placement of a K-wire high and inside the proximal portion of the 5th metatarsal. All screws have a low-profile head to minimize prominence and avoid cuboid impingement. A Jones fracture is a broken bone in a specific part of the fifth metatarsal of the foot between the base and middle part that is known for its high rate of. However, certain situations may require surgical treatment.
The majority of fifth metatarsal fractures are treated without surgery. CLINICAL ANATOMY The fifth metatarsal is located on the lateral side of the foot ( figure 1A-C ). Proximal fifth metatarsal fractures that are distal to the tuberosity have a. The fifth metatarsal is the last bone at the outside of the foot, and most breaks of the fifth metatarsal occur at the base. All screws have a short thread and blunt tip to minimize disruption to the cortical bone and remain within the intramedullary canal of the 5th metatarsal. Avulsion fractures of the proximal fifth metatarsal tuberosity can usually be managed with a soft dressing. The screws are constructed from Titanium Alloy that is Type II Anodized for improved fatigue strength. The system is made up of 4.0 mm, 4.5 mm, 5.5 mm and 6.2 mm, solid and cannulated screws. Using ice, keeping weight off your foot and elevating your foot can help decrease recovery time. The fifth metatarsal is the bone that runs from the midfoot to the base of the small toe on the outside of the foot.

Avulsion fracture Jones fracture Dancers fracture (also known as a mid-shaft or diaphyseal fracture). The PRECISION® Jones Fracture Screw System offers surgeons 120 unique screw options to address Zone 2 (Jones) fractures at the base of the 5th metatarsal. A fifth metatarsal fracture is a common injury where the bone connecting your ankle to your little toe breaks.
