Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Sports Medicine

Background:

  • Os trigonum syndrome involves pain from the lateral tubercle of the posterior talar process.
  • Causes include synchondrosis disruption, fracture, tenosynovitis, and impingement.
  • It presents diagnostic challenges in clinical practice.

Purpose of the Study:

  • To explore the role of imaging modalities in diagnosing os trigonum syndrome.
  • To discuss the diagnostic challenges associated with this condition.
  • To provide a pictorial essay on the imaging findings.

Main Methods:

  • Review of imaging techniques used for os trigonum syndrome.
  • Analysis of cases presenting with posterior ankle pain.
  • Correlation of imaging findings with clinical symptoms.

Main Results:

  • Imaging modalities are essential for identifying the specific pathologies causing os trigonum syndrome.
  • Different imaging findings correspond to various etiologies like synchondrosis disruption and flexor hallucis longus tenosynovitis.
  • Radiographic and advanced imaging aid in differentiating os trigonum syndrome from other posterior ankle pathologies.

Conclusions:

  • Accurate diagnosis of os trigonum syndrome relies heavily on appropriate imaging.
  • Understanding imaging features is key to effective management and treatment planning.
  • This essay highlights the diagnostic utility of various imaging modalities for os trigonum syndrome.
