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. They happen when you break your fifth metatarsal the bone that joins your pinkie toe to the base of your foot. What is a Jones fracture Jones fractures are a type of broken bone. It can either be a stress fracture (a small. 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. A Jones fracture is a break in the bone that connects your smallest toe to your foot (the fifth metatarsal). Jones fracture: involves fracture in a small area of the fifth metatarsal that receives limited blood supply. Jones fracture surgery is recommended when the fracture is not healing well or re-fracture. The system includes instrumentation designed to facilitate placement of a K-wire high and inside the proximal portion of the 5th metatarsal. 5th Metatarsal Base Fracture (Jones) What should I expect and what can I do to help my foot to heal The pain, tenderness and swelling you are experiencing in. Surgical Treatment of 5th Metatarsal Jones and Stress Fractures. All screws have a low-profile head to minimize prominence and avoid cuboid impingement. 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. Jones fractures occur in a small area of the fifth metatarsal that receives less blood and is therefore more. Tuberosity avulsion fractures represent zone one (Figure (Figure3 3)3-5. What is a Jones fracture A transverse fracture of the metaphyseal diaphyseal. Proximal fifth metatarsal fractures can be classified into three zones as described by Lawrence et al and Dameron4,5.

Jones fractures are caused by sudden force on the outside of the foot when twisted, usually with the heel off the ground. The screws are constructed from Titanium Alloy that is Type II Anodized for improved fatigue strength. As a result, proximal fifth metatarsal fractures were re-classified to avoid the confusing term of Jones fractures. A Jones fracture is a break in the long bone outside the foot ( fifth metatarsal) that connects to the pinky toe. The system is made up of 4.0 mm, 4.5 mm, 5.5 mm and 6.2 mm, solid and cannulated screws. 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.
