Jones fracture
A specific type of fifth metatarsal fracture occurring at the metaphyseal-diaphyseal junction. Notable for poor healing potential in athletes.
Full Definition
A Jones fracture is a fracture of the fifth metatarsal bone at the junction between the metaphysis and diaphysis, approximately 1.5-3 cm distal to the tuberosity. Named after orthopedic surgeon Robert Jones, this injury is particularly problematic in athletes due to the poor blood supply in this region, leading to delayed union or nonunion. It differs from the more common avulsion fracture of the fifth metatarsal base and often requires surgical fixation in competitive athletes to ensure proper healing and timely return to sport.
Usage
Usage note: Distinguish from pseudo-Jones fractures and dancer's fractures in documentation.
