Jones fracture, 5th metatarsal base fracture — from boot immobilisation to intramedullary screw fixation.

The Jones fracture is a specific fracture at the metaphyseal–diaphyseal junction of the 5th metatarsal with a high non-union risk. Modern stratified care: boot immobilisation for select cases; intramedullary screw fixation for athletes and displaced fractures.

Key facts

Jones fracture at a glance.

The essentials, in plain English — what a Jones fracture is, why the blood supply matters, and when to reach for a screw rather than a boot.

  • Definition

    A Jones fracture is a specific fracture of the 5th metatarsal at the metaphyseal–diaphyseal junction — a narrow zone with fragile blood supply.

  • Not an avulsion

    Distinguish the true Jones fracture from a proximal tuberosity avulsion (pseudo-Jones) and from more distal diaphyseal stress fractures — they behave very differently.

  • Watershed blood supply

    A watershed zone at the metaphyseal–diaphyseal junction gives a high non-union rate — this is the single reason Jones fractures need respect.

  • How it is imaged

    Weight-bearing X-ray with dedicated oblique views is the initial standard — CT is added if the fracture pattern or union status is uncertain.

  • Torg classification

    For chronic and stress-related Jones fractures the Torg classification (I acute, II delayed union, III non-union) guides whether to boot or to fix.

  • Fixation is gold-standard

    Intramedullary screw fixation is the gold-standard for athletes, displaced fractures and any Torg II or III lesion — faster return, lower non-union.

Why this guide matters

Right fracture, right pathway.

Jones fractures are misclassified more often than any other 5th metatarsal injury — this guide sets out how the true Jones is identified and treated.

  • Not every 5th MT fracture is a Jones

    Proximal tuberosity avulsions and diaphyseal stress fractures look similar but behave very differently — accurate classification changes the plan.

  • Athletes need fixation, not a boot

    Displaced fractures, athletes and Torg II or III lesions do better with intramedullary screw fixation — faster return, lower non-union.

  • The follow-up X-ray is not optional

    Serial imaging catches delayed union early — the window where a small intervention avoids a much bigger one.

How the diagnosis is made

From lateral foot pain to a clear plan.

The steps an emergency clinician or GP will normally follow, in order — so you know what to expect and why.

  1. 01

    Recognising

    Mechanism of injury

    Classic story is a sudden inversion or forefoot-loading injury — often mid-run, mid-cut or a missed step down a kerb.

  2. 02

    Recognising

    Palpation of 5th metatarsal base

    Pinpoint tenderness at the base of the 5th metatarsal, at the metaphyseal–diaphyseal junction — not over the tuberosity.

  3. 03

    Recognising

    Weight-bearing X-ray

    A weight-bearing AP foot view is the initial standard — it confirms the fracture and shows any displacement under load.

  4. 04

    Confirming

    Oblique and lateral views

    Dedicated oblique and lateral foot views distinguish a true Jones fracture from a tuberosity avulsion or diaphyseal stress fracture.

  5. 05

    Confirming

    CT if uncertain

    CT is added when plain films are equivocal, when union is in doubt, or when planning intramedullary screw fixation.

  6. 06

    Managing

    Assess for cavus foot

    A high-arched cavus foot loads the lateral column and predisposes to Jones and stress fractures — worth spotting early.

  7. 07

    Managing

    Foot and ankle surgery consultation

    Displaced fractures, athletes, Torg II or III lesions and non-unions warrant early foot and ankle surgical review.

Typical timeline: 1–2 weeks from injury to a definitive treatment plan.

Symptoms

What a Jones fracture actually feels like.

The pattern is telling — sharp lateral foot pain, bruising and difficulty weight-bearing after an inversion or forefoot-loading injury.

  • Lateral foot pain

    Sharp pain along the outside of the foot, worst at the base of the 5th metatarsal — hard to ignore on weight-bearing.

  • Bruising over 5th MT

    Ecchymosis tracking along the lateral border of the foot within a day or two of the injury.

  • Difficulty weight-bearing

    Most people find it very difficult to bear full weight through the affected foot without a limp.

  • Local swelling

    Localised swelling over the base of the 5th metatarsal, sometimes with a palpable step in displaced fractures.

  • Non-union symptoms after 3 months

    Persistent lateral foot pain and tenderness beyond three months suggests delayed or non-union — needs re-imaging.

  • Recurrent symptoms

    Symptoms that settle then return with load raise concern for a stress-related Torg II or III lesion rather than a simple acute fracture.

  • Bony deformity

    Visible or palpable deformity at the lateral midfoot in higher-energy or displaced fractures — needs urgent review.

  • Red flag

    Open fracture or signs of compartment syndrome (severe pain, tense swelling, pain on passive stretch) — a surgical emergency.

Treatment

How a Jones fracture is treated in the UK.

A stratified approach — a non-weight-bearing boot for selected non-displaced acute cases, and intramedullary screw fixation for athletes, displaced fractures and delayed or non-union.

  • Non-weight-bearing boot immobilisation

    A non-weight-bearing walker boot for 4–8 weeks is the mainstay for non-displaced acute Jones fractures in non-athletes.

  • Serial X-rays to monitor healing

    Repeat X-rays at intervals through the boot period to confirm callus formation and detect delayed union early.

  • Bone stimulator for non-union

    Low-intensity pulsed ultrasound or an external bone stimulator can be added when healing is slow — an adjunct, not a substitute.

  • Intramedullary screw fixation

    The gold-standard for athletes, displaced fractures and Torg II or III lesions — a percutaneous cannulated screw down the medullary canal.

  • Percutaneous screw fixation

    A minimally invasive fixation technique that shortens recovery and lets many athletes weight-bear early with a lower non-union rate.

  • Bone grafting for non-union

    Established non-unions may need open debridement and autologous bone grafting alongside fixation to achieve solid union.

  • Structured rehab and orthoses

    Graded return-to-load, calf and peroneal strengthening, and orthoses to offload the lateral column — critical after any Jones fracture.

  • Cavus foot correction (specific cases)

    In selected recurrent cases, addressing an underlying cavus foot with orthoses or, rarely, surgery reduces future stress on the 5th metatarsal.

Red flags

When lateral foot pain is more than a simple fracture.

Most Jones fractures heal well with the right pathway. These are the situations that change the plan, or need urgent review.

  • Non-union of Jones fracture

    Persistent pain and tenderness beyond three months with no radiographic union — needs surgical review for fixation and possible grafting.

  • Refracture after fixation

    A repeat fracture through the same site after apparent healing — may indicate hardware failure, incomplete union or persistent lateral overload.

  • Compartment syndrome

    Severe out-of-proportion pain, tense swelling and pain on passive toe movement — a surgical emergency, needs same-hour review.

  • Post-op infection

    Increasing pain, redness, warmth, wound discharge or fever after screw fixation — contact the surgical team the same day.

  • Sural nerve injury (screw path)

    Numbness or burning along the lateral border of the foot after fixation suggests sural nerve irritation from the screw path.

  • Cavus foot with recurrent stress

    Repeated 5th metatarsal stress reactions in a cavus foot needs biomechanical assessment and structured offloading, not just another boot.

  • Open fracture

    Any break in the skin overlying the fracture is an open injury — needs urgent orthopaedic assessment and antibiotics.

  • Delayed union in smokers

    Smoking substantially raises non-union rates in Jones fractures — a clear indication to stop and to consider early fixation.

  • Screw prominence

    Persistent lateral foot pain over the screw head after fixation may reflect a prominent implant — sometimes requires hardware removal.

Living with it

A slow bone, but a very predictable recovery.

Four things that make the biggest difference day to day — respecting the boot, rebuilding the lateral column, sensible footwear and disciplined follow-up.

A quiet reminder

Discipline early beats surgery late.

A few weeks of properly protected weight-bearing is nearly always cheaper than a delayed union that needs a screw and a graft.

  1. 01 Load

    Respect the boot period

    Non-weight-bearing means non-weight-bearing — a few weeks of discipline saves months of chasing a non-union.

  2. 02 Rehab

    Rebuild the lateral column

    A structured programme of calf and peroneal strengthening restores confident push-off and cutting.

  3. 03 Footwear

    Offload with the right shoes

    Supportive shoes and, where indicated, orthoses reduce lateral column load — especially in cavus feet.

  4. 04 Reviews

    Do not skip the follow-up X-rays

    Serial imaging catches delayed union early, when it is still fixable without major surgery.

Frequently asked

Everything we get asked about Jones fractures.

Quick answers on classification, boot versus screw, return to sport and the red flags to watch for.

  • What is a Jones fracture, exactly?

    A Jones fracture is a fracture of the 5th metatarsal at the metaphyseal–diaphyseal junction — a narrow watershed zone at the base of the little-toe bone. It is not the same as a proximal tuberosity avulsion (pseudo-Jones) or a more distal diaphyseal stress fracture.

  • Why is the non-union rate so high?

    The metaphyseal–diaphyseal junction has a watershed blood supply — two vascular territories meet there with limited overlap. That anatomy is the single biggest reason Jones fractures heal slowly, and why smoking, weight-bearing too early or missing the diagnosis all matter more than they would elsewhere.

  • Boot or screw — how is that decided?

    Non-displaced acute Jones fractures in non-athletes are usually treated in a non-weight-bearing boot for 4–8 weeks with serial X-rays. Athletes, displaced fractures and Torg II or III (delayed and non-union) lesions are offered intramedullary screw fixation — faster return to sport and lower non-union rates.

  • What is the Torg classification?

    Torg I is an acute fracture with a sharp line and no intramedullary sclerosis. Torg II shows a widened fracture line and early intramedullary sclerosis — a delayed union. Torg III is an established non-union with obliteration of the medullary canal. II and III generally need fixation rather than more boot.

  • How long until I can run again?

    After boot immobilisation, most people are walking normally by 8–12 weeks and return to running progressively over the following weeks. After intramedullary screw fixation, athletes commonly return to sport within 8–12 weeks, guided by clinical and radiographic union.

  • What is the red flag I should not ignore?

    Severe out-of-proportion pain with tense swelling and pain on passive toe movement suggests compartment syndrome — a surgical emergency. Open wounds over the fracture, new numbness after surgery, or signs of infection after fixation also need same-day review.
