Its proximal portion is divided into three parts: the tuberosity (or styloid), intermetatarsal zone (metaphysis), and proximal diaphysis. by James McCormack Fitness Foot Pain Hip Pain 5th Metatarsal fracture: Where is it 5th Metatarsal fracture is a very common cause of foot pain. A Jones fracture can be a stress fracture, which is a small hairline break or crack. Metaphyseal arteries and diaphyseal nutrient arteries provide the blood supply to the fifth metatarsal base. CLINICAL ANATOMY The fifth metatarsal is located on the lateral side of the foot ( figure 1A-C ). A Jones fracture is a break in the fifth metatarsal, a bone of the foot. Additionally, a patient may sustain a shaft fracture greater than 1.5 cm distal to the tuberosity, a long spiral fracture extending into the distal metaphyseal area, the so-called dancer's fracture, or a stress fracture of the metatarsal.Ĭlassification of these fractures is crucial to making management decisions. Fractures through zone 1 are called pseudo-Jones fractures, and fractures through zone 2 are referred to as Jones fractures. Usually, a surgical procedure to treat a Jones fracture will involve the inserting of a screw into the metatarsal bone. Nevertheless, it is critical that the clinician recognizes all injury patterns of the fifth metatarsal and initiate the appropriate treatment plan or referral process to avoid potential complications.Ĭlassified by Lawrence and Bottle, the base, or proximal aspect, of the fifth metatarsal is broken up into three anatomical zones: zone 1, the tuberosity zone 2, the metaphyseal-diaphyseal junction and zone 3, the diaphyseal area within 1.5 cm of the tuberosity. Will RICE treatment be enough for this Jones/Pseudo Jones fracture lolorenee95 Fracture of 5th metatarsal, 6 weeks from date of injury. Since orthopedic surgeon Sir Robert Jones first described these fractures in 1902, there has been an abundance of literature focused on the proximal aspect of the fifth metacarpal due to its tendency towards poor bone healing. Jones fractures occur in a small area of the fifth metatarsal that receives less blood and is therefore more. Waking up in pain stopped after the first 7-10 days in my experience but a wrist is much smaller and less severe as a metatarsal fracture plus it’s further from the heart. ![]() ![]() Plain radiographs are usually adequate Must distinguish Jones fracture from diaphyseal stress freacture: Acute fracture will have narrow fracture line that appears sharp, normal thin cortex adjacent to fracture, and normal. ![]() Fractures of the fifth metatarsal are common injuries that must be recognized and treated appropriately to avoid poor clinical outcomes for the patient.
