Rolled your ankle months ago, and the ankle itself is fine, but the outside of your foot still aches every time you push off? Or you are a dancer or a runner with stubborn pain along the outer edge of your midfoot that nobody has been able to name?
There is a commonly missed diagnosis that fits that description well. It is called cuboid syndrome, and one of the reasons it gets missed is that scans often look normal.
In this article
What is cuboid syndrome?
The cuboid is a small, cube-shaped bone sitting on the outer side of your midfoot, between your heel bone and the bases of the fourth and fifth toes. It sits at a busy junction and plays a role in how your foot transfers load as you push off.
Cuboid syndrome describes irritation and disturbed movement at the cuboid and the joint it forms with the heel bone. It is often described in connection with a rolling ankle injury, or with repetitive loading in dancers and runners.
How common is it?
More common than its low profile suggests, particularly in sport.
Often missed because scans look normal
It is largely a clinical diagnosis and imaging is often unremarkable, which is why people can be told nothing is wrong while the foot keeps hurting.
If you rolled an ankle and the outside of your foot never quite came right, those numbers are worth knowing.
What does it feel like?
The pattern is fairly distinctive once you know it:
- Pain along the outside of the midfoot, roughly midway between the heel and the little toe
- Worse on push-off, on uneven ground, and often worse barefoot
- Tenderness that is clearly not the ankle ligaments and clearly not the heel
- Sometimes a vague sense of weakness or the foot not feeling right
- Frequently a history of a rolled ankle, a spike in training, or repetitive work on the toes
Why does it get missed?
Because it is largely a clinical diagnosis. Imaging is often unremarkable, and a normal scan is easy to read as "nothing is wrong". For a patient who is still sore, that is a frustrating place to be left.
It is also easy to lump in with the original ankle sprain, or to blame footwear, so it can drift for months without anyone putting a name to it.
What helps cuboid syndrome?
It is generally considered to respond well to conservative management, and the plan is usually straightforward:
- An assessment to localise the pain and rule out other causes of outer foot pain, including bone stress
- Manual techniques directed at the cuboid and surrounding joints where appropriate
- Padding, taping or in-shoe changes to support the outer midfoot while it settles
- Load management, adjusting running volume, dance hours or standing time rather than stopping altogether
- Foot, calf and ankle strength work, particularly if it followed an ankle sprain
- A graded return to running, jumping or dancing
Our podiatry team in Mount Gravatt assesses outer foot pain for runners, dancers and active people across Brisbane's southside.
When should you seek help?
Consider getting assessed if
Consider getting assessed if outer midfoot pain has lasted more than a couple of weeks, if it followed a rolled ankle and has not settled, or if it consistently limits push-off, running or dancing. Get it looked at promptly if you cannot bear weight, if there is significant swelling or bruising, or if the pain is focal and worsening with activity, so a bone injury can be ruled out.
