Os Trigonum Syndrome
Os trigonum syndrome causes pain at the back of the ankle, especially when pointing the toes. It is common in dancers and athletes. Physiotherapy helps reduce pain, restore movement, and prevent recurrence.
What is Os Trigonum Syndrome?
Os trigonum syndrome is a condition where an extra small bone (called the os trigonum) at the back of the ankle causes pain and irritation.
This bone is present in about 10% of people and usually causes no problems. However, when it gets compressed between the ankle bones during movements like pointing the toes, it can lead to pain and inflammation.
If you are experiencing persistent back-of-ankle pain in Singapore, ACE Physio Sports can help assess and treat the condition effectively.
What Causes Os Trigonum Syndrome?
Os trigonum syndrome usually develops due to repeated stress or compression at the back of the ankle.
Common causes include:
- Repeated toe pointing (ballet, dance, gymnastics)
- Football kicking motions
- Sudden ankle injuries or sprains
- Poor ankle mobility or stiffness
- Tight calf muscles or Achilles tendon
Pain may occur because:
- The extra bone gets “pinched” between ankle bones
- It irritates nearby soft tissues
- It leads to inflammation in the joint
Symptoms of Os Trigonum Syndrome
Symptoms can vary, but most people notice pain at the back of the ankle, especially during movement.
Common symptoms include:
- Pain at the back of the ankle when pointing toes
- Pain when pushing off while walking or running
- Feeling like the ankle is “blocked” or stiff
- Swelling or tenderness near the Achilles tendon
- Difficulty going onto tiptoes
- A small lump felt at the back of the ankle
Real-life search phrases we commonly hear:
- “pain at back of ankle when pointing foot”
- “cannot push off foot properly”
- “ankle pain when dancing or kicking”
- “stiffness at back of ankle after activity”
What Should I Do?
If you suspect os trigonum syndrome, early management is important.
You should:
- Rest from painful activities
- Avoid excessive toe pointing
- Apply ice to reduce inflammation
- Elevate your foot when resting
- Reduce weight-bearing if painful
- Use light compression if swelling is present
If symptoms persist, it is important to seek physiotherapy assessment to confirm the diagnosis and avoid worsening the condition.
What Shouldn’t I Do?
Avoid these common mistakes:
- Ignoring pain and continuing activity
- Repeatedly pushing through ankle pain
- Returning to sports too early
- Overstretching aggressively without guidance
These can worsen irritation and delay recovery.

Recovery and Long-Term Effects
With proper physiotherapy, most people recover well without surgery.
Typical recovery timeline:
- Mild cases: 2–4 weeks
- Moderate cases: 4–8 weeks
- Chronic cases: may take longer
If symptoms persist or keep coming back, surgery may be considered.
Os Trigonum Surgery:
- Involves removal of the extra bone
- Helps relieve pain and improve ankle movement
After surgery:
- Physiotherapy is essential
- Focus on restoring mobility, strength, and function
- Gradual return to sport
Without proper rehab, stiffness after surgery and reduced ankle performance can occur.

Frequently Asked Questions
Why does my foot hurt most in the morning or when I first start walking?
First-step pain is a classic feature of many foot and ankle conditions, including Os Trigonum Syndrome. It occurs when irritated structures are suddenly loaded after a period of rest. Physiotherapy addresses the underlying cause and provides strategies to reduce this painful cycle.
Can I keep walking or exercising with Os Trigonum Syndrome?
In most cases, complete rest is counterproductive. Low-impact activity and physiotherapy-guided exercises maintain fitness while allowing healing. Your therapist will advise which activities are safe and how to progress load gradually through each stage of recovery.
How long does Os Trigonum Syndrome usually take to resolve with physiotherapy?
Recovery typically takes 6–12 weeks, though chronic cases may take longer. Physiotherapy accelerates healing through load management, manual therapy, and progressive strengthening of the foot and ankle musculature.
