Summary
Triangular fibrocartilage (TFC) tears are uncommon in children without trauma. This case highlights incidental TFC tears in a 12-year-old boy with negative ulnar variance, challenging typical understandings of TFC pathology.
Area of Science:
- Orthopedics
- Sports Medicine
- Radiology
Background:
- The triangular fibrocartilage complex (TFCC) stabilizes the distal radioulnar joint.
- Triangular fibrocartilage (TFC) tears are typically associated with positive ulnar variance and degenerative changes.
- TFC tears are rare in young individuals without a history of trauma.
Observation:
- A 12-year-old male presented with bilateral incidental findings of TFC tears.
- The patient had no history of traumatic injury to the wrists.
- Both wrists exhibited negative ulnar variance.
Findings:
- This case presents a rare occurrence of bilateral TFC tears in a pediatric patient.
- The absence of trauma and presence of negative ulnar variance are atypical for TFC tears.
- The findings suggest potential alternative mechanisms or etiologies for TFC tears in adolescents.
Implications:
- This case may prompt a re-evaluation of the typical associations with TFC tears.
- Further research is needed to understand the pathogenesis of TFC tears in young, non-traumatic populations.
- Clinical awareness should be heightened for TFC pathology in pediatric patients, even without typical risk factors.
