Summary
A rare case of concurrent os trigonum and soleus tertius anomaly causing chronic posteromedial ankle pain was successfully treated. Surgical resection of the os trigonum provided complete symptom relief, highlighting its therapeutic efficacy.
Area of Science:
- Orthopedic Surgery
- Anatomy
- Sports Medicine
Background:
- Chronic posteromedial ankle pain can significantly impact patient quality of life.
- Anatomical variations, such as os trigonum and soleus tertius, are potential sources of posterior ankle impingement.
- Accurate diagnosis is crucial for effective management of complex ankle pain.
Observation:
- A patient presented with persistent posteromedial ankle pain attributed to coexisting os trigonum and soleus tertius.
- Physical examination and imaging studies confirmed the presence of both anomalies.
- Conservative treatments failed to alleviate the patient's chronic symptoms.
Findings:
- Surgical resection of the os trigonum was performed.
- The patient experienced complete resolution of ankle pain following the procedure.
- The soleus tertius anomaly did not necessitate surgical intervention in this case.
Implications:
- Os trigonum syndrome is a treatable cause of posteromedial ankle pain.
- Surgical excision of os trigonum is an effective treatment for refractory cases.
- Concurrent anatomical anomalies should be considered in the differential diagnosis of chronic ankle pain.
