Understanding.
Impingement is a painful contact between bony structures or soft tissues. It can be aggravated by certain repetitive movements, particularly those involving the toes. A trigone can contribute to posterior impingement, though it is not always the cause.
The assessment.
The examination locates the pain and also looks for damage to nearby tendons. X-rays, ultrasound, MRI, or CT scan are chosen depending on the suspected structure.
Treatments.
Activity adjustments and rehabilitation are often the first approach. If a specific cause is identified and the discomfort persists, an arthroscopic or endoscopic procedure may be considered.
Follow-up.
Resumption depends on the treated tissue and functional recovery.
Identifying the cause of the conflict
Pain in the toes can originate from a bony prominence or soft tissue. It is also necessary to distinguish between involvement of the peroneal tendons or other nearby structures. A targeted injection can sometimes help to determine the origin and provide relief.
If intervention is deemed appropriate
The procedure treats the responsible structure; an os trigonum is only removed if it contributes to the symptoms. Recovery depends on the associated procedures. Stiffness, residual pain, and nerve irritation are among the risks to be discussed.
Your questions.
Does a visible os trigonum require surgery?+
No. Imaging must correspond to the symptoms and the clinical examination.
Are all external pains caused by impingement?+
No. The examination must locate the pain before attributing the symptoms to a bone lesion.
Can I continue dancing or playing sports with pointe work?+
Triggering movements are temporarily modified; resumption of activity is gradual, depending on tolerance and treatment.
