Presentation
Presented with a history of recurrent right wrist dorsal region swelling and pain for the last 1 to 2 years. Intramedullary nail fixation was done across the right radius fracture about 18 years before the presentation.
Patient Data
There is nail fixation across the healed fracture of the distal radius shaft. The distal end of the nail projects beyond radius. The 4th metacarpus shows an old malunited fracture. There is no bone lesion/ dislocation.
There is tenosynovitis involving 2nd and 3rd extensor compartments. There is effusion, synovial hypertrophy without hypervascularity. Tendons of both compartments are intact and show normal fibrillary echopattern. The distal end of the radius nail is about 6 mm outside the bone. It is localized by a reverberation artifact. With wrist flexion, the nail touches the extensor carpi radialis longus tendon. There is also wrist joint effusion.
Case Discussion
The case shows wrist extensor compartments tenosynovitis due to the radius nail.
