Case in brief
A 50-year-old man presented with restricted forearm rotation due to radioulnar synostosis, which developed 15 months after an isolated undisplaced distal ulna fracture. Imaging confirmed a mature bony bridge between the radius and ulna. Surgical excision of the heterotopic bone was performed, resulting in near-complete restoration of forearm motion without recurrence at 2 years follow-up.
Diagnostic / clinical pearl
Clinicians should be aware that radioulnar synostosis can occur as a rare complication following isolated distal ulna fractures, leading to significant functional impairment.
Why it matters
Understanding this association is crucial for timely diagnosis and intervention, as surgical excision can restore forearm function effectively.
