Fifth metatarsal fractures are a common bone injury, especially in athletes and active individuals, and are classified based on their location along the bone. The fifth metatarsal is the outermost long bone of the foot, articulating with the cuboid and the fifth toe. It serves as an attachment site for the peroneus brevis tendon laterally and the plantar fascia medially, making it vulnerable to both avulsion and stress-related injuries. Its unique anatomy—including a watershed area with limited blood supply contributes to variable healing outcomes.
Fractures are typically divided into three zones:
Treatment will vary between fractures with considerations in displacement, patient activity level, and healing potential needed, but all treatment plans are commenced by a GP, Sports Physician and/or the fracture clinic at the local hospital. Zone 1 fractures usually respond well to conservative management with protected weight-bearing. Zone 2 and 3 fractures, due to poor vascularity and mechanical stress, may require surgical fixation, especially in high-demand individuals.
Accurate diagnosis via imaging and clinical assessment is essential, so early intervention with our team of physiotherapists is important to prevent chronic dysfunction. Differential diagnoses include peroneal tendon injuries, midfoot sprains, and stress reactions, and this is cleared with objective clinical testing and imaging.
If you believe you have a fifth metatarsal fracture, it is important to consult your OHL physiotherapist as soon as possible so an accurate diagnosis and appropriate referral can be given. You can do this by calling 9431 5955 or you can book online via the Client Portal on the website.
