Area of Science:

  • Orthopedics
  • Sports Medicine
  • Anatomy

Background:

  • The os trigonum is a common accessory bone located dorsal to the talus.
  • Os trigonum syndrome involves pain in the back of the foot due to this ossicle.

Observation:

  • This condition frequently affects athletes engaged in activities causing intense foot stress, such as ballet dancers (en-pointe position) and soccer players (plantarflexion).
  • The flexor hallucis tendon is notably under maximal tension in these scenarios.

Findings:

  • The abstract details typical complaints, clinical findings, and various therapeutic strategies for os trigonum syndrome.
  • Two case studies are presented to illustrate these aspects.

Implications:

  • Non-operative treatments are the initial approach.
  • Surgical excision of the os trigonum is the primary treatment when non-operative methods are ineffective.
