Pediatric trans-olecranon fracture dislocation of the elbow associated with fracture of the radial head and with medial collateral ligament lesion: A case report and review of the literature

"TRASH" Transolecranon Fracture-Dislocation with Occult Osteochondral Coronoid Fracture: A Case Report

CASE

A 7-year-old girl sustained a radiographic appearance seemed harmless (TRASH) elbow lesion after falling from play equipment. Initial radiographs demonstrated a transolecranon fracture-dislocation. Additional injury was suspected, given valgus instability after reduction. Subsequent magnetic resonance imaging (MRI) revealed a large osteochondral coronoid fragment only partially visible on initial radiographs and computed tomography (CT). Successful outcomes were achieved by ulnar nerve decompression, open reduction, and fixation.

CONCLUSION

TRASH lesions, including this osteochondral coronoid injury, may be overlooked in younger children because of an abundance of unossified cartilage. A high index of suspicion and early MRI can lead to successful diagnosis and treatment.
