What Is a Fifth Metatarsal Fracture?
A fifth metatarsal fracture is a break in the long bone on the outer (lateral) side of the foot that connects the midfoot to the little toe. It is one of the most common foot fractures seen in emergency departments and sports clinics, often described by patients as a “broken metatarsal” or simply a “broken foot”.
The fifth metatarsal is anatomically vulnerable. It has a prominent base (tuberosity) where the peroneus brevis tendon attaches, a narrow neck region with a relatively poor blood supply, and a long shaft that takes much of the load when the foot pushes off the ground during running, cutting and jumping. These features explain why fifth metatarsal fractures behave very differently depending on exactly where the break occurs.
Because outcomes — and the right treatment — depend almost entirely on the precise location of the fracture, specialist assessment by a Consultant Foot & Ankle Surgeon is strongly recommended, particularly for athletes and active patients. Mr Matthew Welck is a Consultant Foot & Ankle Surgeon at the Royal National Orthopaedic Hospital (RNOH) Stanmore and UCL, and offers private assessment for fifth metatarsal and other foot and ankle sports injuries across London and North London.
