The fifth metatarsal — the long bone on the outer edge of the foot — is one of the most commonly fractured bones in the foot and ankle, yet not all fifth metatarsal fractures are the same. The location of the fracture along the fifth metatarsal determines blood supply, healing potential, and the appropriate treatment — the difference between a fracture that heals readily in a boot and one that requires surgical fixation to prevent non-union can come down to millimeters of fracture location.
Types of Fifth Metatarsal Fractures
Zone 1: Avulsion Fracture (Pseudo-Jones Fracture)
The most common fifth metatarsal fracture — a small flake of bone pulled off the base of the fifth metatarsal by the peroneus brevis tendon or plantar fascia during an ankle inversion injury. The fracture line runs perpendicular to the metatarsal shaft, at the very tip of the tuberosity. Despite the dramatic-sounding mechanism, Zone 1 fractures have an excellent blood supply and heal reliably with conservative management in 4–6 weeks in a stiff-soled shoe or boot. Surgery is rarely needed.
Zone 2: Jones Fracture
The most clinically important fifth metatarsal fracture — occurring at the metaphyseal-diaphyseal junction, in the “watershed zone” where arterial blood supply is poorest. The Jones fracture was first described by orthopedic surgeon Sir Robert Jones in 1902 (he sustained the injury himself while dancing). Because of the tenuous blood supply at this location, Jones fractures have a high rate of non-union (failure to heal) and refracture with conservative treatment. Athletic patients, high-demand patients, and anyone requiring rapid return to full activity are typically recommended surgical fixation.
Zone 3: Diaphyseal (Shaft) Stress Fracture
Fatigue fracture of the fifth metatarsal shaft from repetitive loading — seen in runners, basketball players, and military recruits. May present as chronic outer foot pain rather than a single acute injury event. Stress fractures in Zone 3 have even poorer healing potential than Jones fractures and almost always require surgical fixation in athletes.
Symptoms
- Pain at the outer border of the foot at or near the base of the fifth metatarsal
- Tenderness to palpation directly over the fracture site
- Swelling and bruising on the outer foot
- Difficulty weight-bearing
- Often mistaken for “just a sprain” — X-ray is required to confirm
Diagnosis
Weight-bearing foot X-rays confirm the fracture and precisely locate it within the three zones. Dr. Biernacki obtains digital X-rays at the first visit at Balance Foot & Ankle. When X-rays appear normal but clinical suspicion is high (particularly for stress fractures), MRI reveals bone marrow edema before a fracture line is visible.
Treatment by Fracture Type
Zone 1 (Avulsion)
Weight-bearing in a stiff-soled shoe or walking boot for 4–6 weeks. No surgery in the vast majority of cases. Ice, elevation, and NSAIDs acutely. Return to sport at 4–6 weeks when pain-free with impact activities.
Zone 2 (Jones Fracture)
- Conservative — non-weight-bearing cast for 6–8 weeks; appropriate for non-athletes, elderly patients, and patients who cannot tolerate surgery; non-union rate 25–30%
- Surgical (recommended for athletes) — intramedullary screw fixation; a single large-diameter intramedullary screw down the medullary canal of the fifth metatarsal provides rigid fixation that allows weight-bearing in 2–3 weeks; dramatically reduces non-union rate to under 5% and accelerates return to sport by 8–12 weeks compared to cast treatment
Zone 3 (Stress Fracture)
Surgical intramedullary screw fixation is the standard of care for athletes and active patients. Non-operative treatment has unacceptably high refracture rates in this zone.
Rehabilitation and Return to Sport
After Zone 2 or Zone 3 surgery, progressive weight-bearing begins at 2–3 weeks, and return to sport occurs at 8–12 weeks when radiographic union is confirmed. A custom orthotic with lateral heel wedge reduces fifth metatarsal stress after healing and during the return-to-sport phase.
Outer Foot Fracture Evaluation and Treatment
Dr. Biernacki evaluates fifth metatarsal fractures with on-site X-ray at the first visit and provides appropriate conservative or surgical management. Same-week appointments at Bloomfield Hills and Howell.
