Understanding.
The sesamoid bones are two small bones located under the head of the first metatarsal bone. A fracture can be traumatic or related to overuse.
The assessment.
X-rays, sometimes supplemented by an MRI or CT scan, distinguish a sesamoid fracture from one that is naturally multi-part.
Treatments.
Weight-bearing and immobilization protect healing. Surgery may be considered if the fracture is displaced or fails to heal.
Follow-up.
Weight-bearing should be resumed according to instructions and progress.
Healing is sometimes slow.
A protective shoe or immobilization will limit stress. Weight-bearing will be adjusted based on the assessment; discomfort may last for several months. Persistent pain may warrant a follow-up appointment to assess bone healing.
If treatment is insufficient
A displaced fracture or failure to heal may lead to discussions about fixation or excision. Preserving the balance of the big toe is a factor in the decision.
Your questions.
Can I continue running?+
The impacts must be suspended until reassessment.
Is a bone in two parts necessarily broken?+
No. A bipartite sesamoid can be an anatomical variant; imaging and symptoms allow for differentiation.
When to resume impact activities?+
After reassessment of pain and healing, according to the surgeon's instructions.
