Presentation
History of intramedullary nail fixation across a left radius-ulna fracture about 2 years ago. Complaining of dorsal wrist pain and swelling for the last few weeks. No recent trauma.
Patient Data
There is intramedullary nail fixation across healed fracture of radius and ulna shaft. There is no dislocation or recent fracture. There is no bone lesion.
About 10 mm length of the radial nail is outside the distal end of the radius at the wrist dorsum. This nail is impinging extensor carpi radialis longus tendon with wrist flexion. There is no impingement with the neutral position of the wrist. There is an effusion with echoes in the 2nd and 3rd extensor compartment synovial sheaths without tendon tear. The nail is causing reverberation artifact.
Case Discussion
Findings favor soft tissue impingement at the wrist due to an intramedullary nail in the radius with extraosseous extension. There is tenosynovitis involving the 2nd and 3rd extensor compartments.
