Jones Fracture: Fracture of the proximal diaphysis of the 5th metatarsal, distal to the tuberosity, without joint involvement. Caused by foot inversion / twisting and repetitive stress
The term ‘Jones fracture’ is used inconsistently; some referring to fracture at the metaphyseal-diaphyseal junction and others define it as a fracture at the proximal diaphysis.
The ‘Zone I, II, III‘ method of description is more accurate, replicable and assists in determining immediate treatment and ongoing management.
1902 – Sir Robert Jones, general surgeon with a passion for orthopaedics and radiology, sustained this injury whilst dancing. In 1902 he wrote up a case report of five similar injuries specifically noting that the fracture is caused by ‘indirect violence’
‘Whilst dancing, I trod on the outer side of my foot, my heel at the moment being off the ground. Something gave way midway down my foot, and I at once suspected a rupture of the peroneus longus tendon…The following morning I carefully examined my foot and discovered that my tendon was intact. There was a slight swelling over the base of the fifth metatarsal bone… A finger on the spot gave exquisite pain…Extension of the ankle and flexion of the toes were immediately felt at the base of the fifth metatarsal. I hobbled down-stairs to my colleague…to X-ray my foot. This was done, and the fifth metatarsal was found fractured about three-fourths of an inch from its base.’ [Jones R, Ann Surg. 1902. p697]
1960 – Stewart differentiated an avulsion fracture of the tuberosity / styloid from fractures of the proximal diaphysis. He named the latter: ‘Jones fracture’.
1984 – Torg et al report fractures of proximal diaphysis are likely located at a site of pre-existing stress pressure.
1993 – Lawrence and Botte release a classification system distinguishing 3 zones
- Zone 1: Tuberosity avulsion fracture, with or without involvement of the tarsometatarsal articulation. Caused by forces by the peroneus brevis tendon or the lateral band of the plantar fascia during foot inversion.
- Zone 2: Jones fracture; metaphysis-diaphysis junction fracture, which extend into the fourth-fifth intermetatarsal facet. Caused by forced forefoot adduction with the hindfoot in plantar flexion.
- Zone 3: Diaphyseal stress fracture; proximal diaphyseal fractures, distal to the fourth and fifth metatarsal base articulation. Caused by acute excessive bearing of the region or chronic overloading as in stress fractures
