Overview
A Jones fracture is a specific break at the base of the fifth metatarsal — the outer bone of the foot — in a watershed blood-supply zone. Because the blood supply is sparse, these fractures are prone to delayed union and nonunion, especially in athletes and in patients with high activity demands.
Operative fixation is often preferred in active patients and athletes who want a quicker, more predictable return to sport. Non-operative treatment with strict non-weight-bearing casting remains an option, particularly in less active patients, but takes longer and carries a higher nonunion risk.
Why it's done
Fifth metatarsal (Jones) ORIF is typically considered when imaging and the clinical picture together indicate that the fracture will not reliably heal or function without surgical stabilization. Common indications include:
Active or athletic patient
A more predictable return to cutting and running sports.
Displaced fracture
Displacement lowers the already-marginal healing rate.
Delayed or nonunion from prior non-operative care
A screw plus biologic augmentation often salvages a stalled fracture.
Chronic stress reaction at the Jones site
Prophylactic fixation may be appropriate in an in-season athlete.
How it works
Through a small incision at the base of the fifth metatarsal, a cannulated solid screw is driven down the medullary canal of the bone under fluoroscopic guidance. The screw compresses the fracture and acts as an internal splint.
In high-risk patients or in nonunion cases, bone graft or biologic augmentation may be added.
Recovery
Patients are typically non-weight-bearing in a boot during early recovery, then allowed to progress weight-bearing in the boot. Return to running and cutting activity is held until X-rays confirm union. Screws are left unless symptomatic. Re-fracture through or around the screw is a known risk, particularly if the patient returns to sport before full radiographic union.

Weight-Bearing After Repair
Controlled load is part of how bone heals. Once the fracture is stabilized with hardware, gentle weight through the limb stimulates the biology that builds callus and remodels bone — completely offloading a fixed fracture for too long can actually slow healing and stiffen the joint above and below. Full body weight right away, however, can overload the construct before bone has caught up. The right answer sits in between: a partial weight-bearing progression decided by your surgeon based on your fracture pattern, the strength of the fixation, your bone quality, and how the repair looks on post-op imaging. We tell you exactly how much weight the limb can take, when to advance, and what to watch for.
Risks & Why We Still Recommend It
Every operation carries risk. The reason we offer this procedure is that the condition, left untreated, causes a non-union at the base of the fifth metatarsal — this zone has notoriously poor blood supply and frequently fails to heal in a cast. That is the trade we are managing — not eliminating risk, but choosing the smaller of two unfavorable trajectories.
The risks we discuss with patients before fifth metatarsal (jones) orif include:
- bleeding and infection
- anesthesia risk
- sural nerve irritation
- non-union or re-fracture despite fixation
- hardware irritation requiring later removal
- stiffness
The indication to proceed is a true Jones (fifth metatarsal metaphyseal-diaphyseal) fracture in an athlete or a patient who cannot accept the non-union rate of cast treatment. Patients who don't need this operation don't get it.
